159-536: The standard edition of the surviving fragments and testimonies is Leonardo Tarán's Speusippus of Athens: A Critical Study with a Collection of the Related Texts and Commentary (1982). Speusippus was a native of Athens , and the son of Eurymedon and Potone , a sister of Plato , he belonged to the deme of Myrrhinus . The pseudonymous Thirteenth Letter of Plato claims that Speusippus married his niece (his mother's granddaughter). We hear nothing of his life until

318-570: A gymnasium and a colonnade ( peripatos ), from which the school acquired the name Peripatetic . Aristotle conducted courses and research at the school for the next twelve years. He often lectured small groups of distinguished students and, along with some of them, such as Theophrastus , Eudemus , and Aristoxenus , Aristotle built a large library which included manuscripts, maps, and museum objects. While in Athens, his wife Pythias died and Aristotle became involved with Herpyllis of Stagira. They had

477-408: A national park . The Athens urban area spreads over 50 kilometres (31 mi) from Agios Stefanos in the north to Varkiza in the south. The city is located in the north temperate zone, 38 degrees north of the equator. Athens is built around a large number of hills. Lycabettus is one of the tallest hills of the city proper and provides a view of the entire Attica Basin. The meteorology of Athens

636-541: A "survival of the fittest" origin of living things and their organs, and ridiculed the idea that accidents could lead to orderly results. To put his views into modern terms, he nowhere says that different species can have a common ancestor , or that one kind can change into another , or that kinds can become extinct . Aristotle did not do experiments in the modern sense. He used the ancient Greek term pepeiramenoi to mean observations, or at most investigative procedures like dissection. In Generation of Animals , he finds

795-423: A complete definition who did not know all the differences by which a thing which was to be defined was separated from the rest. Like Plato, Speusippus distinguished between that which is the object of thought , and that which is the object of sensuous perception , between the cognition of the reason and sensuous perception. He tried, however, to show how perception can be taken up and transformed into knowledge, by

954-519: A complex synthesis of the various philosophies existing prior to him. His teachings and methods of inquiry have had a significant impact across the world, and remain a subject of contemporary philosophical discussion. Aristotle's views profoundly shaped medieval scholarship . The influence of his physical science extended from late antiquity and the Early Middle Ages into the Renaissance , and

1113-552: A daughter whom they also named Pythias. In 343/42 BC, Aristotle was invited to Pella by Philip II of Macedon in order to become the tutor to his thirteen-year-old son Alexander ; a choice perhaps influenced by the relationship of Aristotle's family with the Macedonian dynasty. Aristotle taught Alexander at the private school of Mieza , in the gardens of the Nymphs , the royal estate near Pella. Alexander's education probably included

1272-438: A fertilized hen's egg of a suitable stage and opens it to see the embryo's heart beating inside. Instead, he practiced a different style of science: systematically gathering data, discovering patterns common to whole groups of animals, and inferring possible causal explanations from these. This style is common in modern biology when large amounts of data become available in a new field, such as genomics . It does not result in

1431-497: A fluid such as air. In this system, heavy bodies in steady fall indeed travel faster than light ones (whether friction is ignored, or not ), and they do fall more slowly in a denser medium. Newton's "forced" motion corresponds to Aristotle's "violent" motion with its external agent, but Aristotle's assumption that the agent's effect stops immediately it stops acting (e.g., the ball leaves the thrower's hand) has awkward consequences: he has to suppose that surrounding fluid helps to push

1590-455: A house is the bricks, stones, timbers, etc., or whatever constitutes the potential house, while the form of the substance is the actual house, namely 'covering for bodies and chattels' or any other differentia that let us define something as a house. The formula that gives the components is the account of the matter, and the formula that gives the differentia is the account of the form. Like his teacher Plato, Aristotle's philosophy aims at

1749-427: A land area of 38.96 km (15.04 sq mi). Athens is one of the world's oldest cities , with its recorded history spanning over 3,400 years, and its earliest human presence beginning somewhere between the 11th and 7th millennia BC . According to Greek mythology the city was named after Athena , the ancient Greek goddess of wisdom, but modern scholars generally agree that the goddess took her name after

1908-546: A landmark new blue glass roof which was added to the main stadium. A second Olympic complex, next to the sea at the beach of Palaio Faliro, also features modern stadia, shops and an elevated esplanade. Work is underway to transform the grounds of the old Athens Airport – named Elliniko – in the southern suburbs, into one of the largest landscaped parks in Europe, to be named the Hellenikon Metropolitan Park . Many of

2067-597: A linear scale, and noted various exceptions, such as that sharks had a placenta like the tetrapods. To a modern biologist, the explanation, not available to Aristotle, is convergent evolution . Philosophers of science have generally concluded that Aristotle was not interested in taxonomy, but zoologists who studied this question in the early 21st century think otherwise. He believed that purposive final causes guided all natural processes; this teleological view justified his observed data as an expression of formal design. Aristotle's psychology , given in his treatise On

2226-485: A lingering paralytic illness, presumably a stroke . He was succeeded as the head of the school by Xenocrates . Diogenes Laërtius gives us a list of some of the titles of the many dialogues and commentaries of Speusippus, which is of little help in determining their contents, and the fragments provided by other writers provide us with only a little extra. Speusippus was interested in bringing together those things which were similar in their philosophical treatment, and in

2385-480: A number of subjects, such as ethics and politics , as well as standard literary texts, like Euripides and Homer . It is likely that during Aristotle's time in the Macedonian court, other prominent nobles, like Ptolemy and Cassander , would have occasionally attended his lectures. Aristotle encouraged Alexander toward eastern conquest, and his own attitude towards Persia was strongly ethnocentric . In one famous example, he counsels Alexander to be "a leader to

2544-435: A part of particular things. For example, it is possible that there is no particular good in existence, but "good" is still a proper universal form. Aristotle disagreed with Plato on this point, arguing that all universals are instantiated at some period of time, and that there are no universals that are unattached to existing things. In addition, Aristotle disagreed with Plato about the location of universals. Where Plato spoke of

2703-516: A population of 3,638,281 according to the 2021 census. Athens and Piraeus municipalities serve as the two metropolitan centres of the Athens Metropolitan Area. There are also some inter-municipal centres serving specific areas. For example, Kifissia and Glyfada serve as inter-municipal centres for northern and southern suburbs respectively. The Athens Metropolitan Area consists of 58 densely populated municipalities, sprawling around

2862-498: A priori principles. Aristotle's "natural philosophy" spans a wide range of natural phenomena including those now covered by physics, biology and other natural sciences. In Aristotle's terminology, "natural philosophy" is a branch of philosophy examining the phenomena of the natural world, and includes fields that would be regarded today as physics, biology and other natural sciences. Aristotle's work encompassed virtually all facets of intellectual inquiry. Aristotle makes philosophy in

3021-418: A property or a relation to other things. When one looks at an apple, for example, one sees an apple, and one can also analyse a form of an apple. In this distinction, there is a particular apple and a universal form of an apple. Moreover, one can place an apple next to a book, so that one can speak of both the book and apple as being next to each other. Plato argued that there are some universal forms that are not

3180-466: A rational perception of them. Speusippus rejected Plato's Theory of Forms ; whereas Plato distinguished between ideal numbers (i.e. the Platonic Forms of numbers) and mathematical numbers, Speusippus rejected the ideal numbers, and consequently the ideas . He tried to determine the idea of substance more distinctly by separating its types, the difference between which he considered would result from

3339-602: A set of six books called the Organon around 40 BC by Andronicus of Rhodes or others among his followers. The books are: The order of the books (or the teachings from which they are composed) is not certain, but this list was derived from analysis of Aristotle's writings. It goes from the basics, the analysis of simple terms in the Categories, the analysis of propositions and their elementary relations in On Interpretation , to

3498-537: A significant naval power with a large fleet, and helped the rebellion of the Ionian cities against Persian rule. In the ensuing Greco-Persian Wars Athens, together with Sparta, led the coalition of Greek states that would eventually repel the Persians, defeating them decisively at Marathon in 490 BC, and crucially at Salamis in 480 BC. However, this did not prevent Athens from being captured and sacked twice by

3657-549: A son whom Aristotle named after his father, Nicomachus . This period in Athens, between 335 and 323 BC, is when Aristotle is believed to have composed many of his philosophical works. He wrote many dialogues, of which only fragments have survived. Those works that have survived are in treatise form and were not, for the most part, intended for widespread publication; they are generally thought to be lecture aids for his students. His most important treatises include Physics , Metaphysics , Nicomachean Ethics , Politics , On

3816-549: A thrown stone, in the Physics (254b10), and "natural motion", such as of a falling object, in On the Heavens (300a20). In violent motion, as soon as the agent stops causing it, the motion stops also: in other words, the natural state of an object is to be at rest, since Aristotle does not address friction . With this understanding, it can be observed that, as Aristotle stated, heavy objects (on

3975-575: A triangle defined by the Acropolis, the ancient cemetery of Kerameikos and the new palace of the Bavarian king (now housing the Greek Parliament ), so as to highlight the continuity between modern and ancient Athens. Neoclassicism, the international style of this epoch, was the architectural style through which Bavarian, French and Greek architects such as Hansen, Klenze, Boulanger or Kaftantzoglou designed

4134-533: A very impure source: Athenaeus and Diogenes Laërtius can adduce as authority for them scarcely anything more than the abuse in some spurious letters of Dionysius the Younger , who was banished by Dion, with the cooperation of Speusippus. Having been selected by Plato as his successor as the leader ( scholarch ) of the Academy , he was at the head of the school for only eight years (348/7–339/8 BC). He died, it appears, of

4293-544: A woman with origins from Chalcis , Euboea . Nicomachus was said to have belonged to the medical guild of Asclepiadae and was likely responsible for Aristotle's early interest in biology and medicine. Ancient tradition held that Aristotle's family descended from the legendary physician Asclepius and his son Machaon . Both of Aristotle's parents died when he was still at a young age and Proxenus of Atarneus became his guardian. Although little information about Aristotle's childhood has survived, he probably spent some time in

4452-425: Is a change where the substrate of the thing that has undergone the change has itself changed. In that particular change he introduces the concept of potentiality ( dynamis ) and actuality ( entelecheia ) in association with the matter and the form. Referring to potentiality, this is what a thing is capable of doing or being acted upon if the conditions are right and it is not prevented by something else. For example,

4611-454: Is a historical accident: his works on botany have been lost, but two books on plants by his pupil Theophrastus have survived. Aristotle reports on the sea-life visible from observation on Lesbos and the catches of fishermen. He describes the catfish , electric ray , and frogfish in detail, as well as cephalopods such as the octopus and paper nautilus . His description of the hectocotyl arm of cephalopods, used in sexual reproduction,

4770-419: Is also a final cause or end. Then Aristotle proceeds and concludes that the actuality is prior to potentiality in formula, in time and in substantiality. With this definition of the particular substance (i.e., matter and form), Aristotle tries to solve the problem of the unity of the beings, for example, "what is it that makes a man one"? Since, according to Plato there are two Ideas: animal and biped, how then

4929-462: Is both the 2nd busiest passenger port in Europe, and the 13th largest container port in the world. The Athens metropolitan area or Greater Athens extends beyond its administrative municipal city limits as well as its urban agglomeration , with a population of 3,638,281 (2021) over an area of 2,928.717 km (1,131 sq mi). The heritage of the Classical Era is still evident in

5088-474: Is bounded by four large mountains: Mount Aigaleo to the west, Mount Parnitha to the north, Mount Pentelicus to the northeast and Mount Hymettus to the east. Beyond Mount Aegaleo lies the Thriasian plain , which forms an extension of the central plain to the west. The Saronic Gulf lies to the southwest. Mount Parnitha is the tallest of the four mountains (1,413 m (4,636 ft)), and has been declared

5247-449: Is connected another which takes a wider range. As the ultimate principle , Speusippus would not, with Plato, recognise the Good , but, with others (who doubtless were also Platonists), going back to the older Theologi , maintained that the principles of the universe were to be set down as causes of the good and perfect, but were not the good and perfect itself, which must rather be regarded as

5406-484: Is deemed to be one of the most complex in the world because its mountains cause a temperature inversion phenomenon which, along with the Greek government's difficulties controlling industrial pollution, was responsible for the air pollution problems the city has faced. This issue is not unique to Athens; for instance, Los Angeles and Mexico City also suffer from similar atmospheric inversion problems. The Cephissus river,

5565-468: Is known about Aristotle's life. He was born in the city of Stagira in northern Greece during the Classical period . His father, Nicomachus , died when Aristotle was a child, and he was brought up by a guardian. At around eighteen years old, he joined Plato 's Academy in Athens and remained there until the age of thirty seven ( c.  347 BC ). Shortly after Plato died, Aristotle left Athens and, at

5724-541: Is man a unity? However, according to Aristotle, the potential being (matter) and the actual one (form) are one and the same. Aristotle's immanent realism means his epistemology is based on the study of things that exist or happen in the world, and rises to knowledge of the universal, whereas for Plato epistemology begins with knowledge of universal Forms (or ideas) and descends to knowledge of particular imitations of these. Aristotle uses induction from examples alongside deduction , whereas Plato relies on deduction from

5883-514: Is only the difficulties which led him to make this and similar deviations from the Platonist doctrine, of which we can get any clear idea, not the way in which he thought he had avoided those difficulties by distinguishing different kinds of principles . The criticism of Aristotle , directed apparently against Speusippus, shows how little satisfied he was with the modification of the original Platonist doctrine. With this deviation from Plato's doctrine

6042-661: Is the most populous in Greece , with a population of 643,452 people (in 2021) and an area of 38.96 km (15.04 sq mi), forming the core of the Athens Urban Area within the Attica Basin. The incumbent Mayor of Athens is Charis Doukas of PASOK. The municipality is divided into seven municipal districts which are mainly used for administrative purposes.

6201-492: Is the first city in Europe to appoint a chief heat officer to deal with severe heat waves . Temperatures of 47.5°C have been reported in several locations of the metropolitan area, including within the urban agglomeration. Metropolitan Athens was until 2021 the holder of the World Meteorological Organization record for the highest temperature ever recorded in Europe with 48.0 °C (118.4 °F) which

6360-413: Is the fulfilment of the end of the potentiality. Because the end ( telos ) is the principle of every change, and potentiality exists for the sake of the end, actuality, accordingly, is the end. Referring then to the previous example, it can be said that an actuality is when a plant does one of the activities that plants do. For that for the sake of which ( to hou heneka ) a thing is, is its principle, and

6519-536: The 2004 Summer Olympics , making it one of five cities to have hosted the Summer Olympics on multiple occasions. In Ancient Greek , the name of the city was Ἀθῆναι ( Athênai , pronounced [atʰɛ̂ːnai̯] in Classical Attic ), which is a plural word. In earlier Greek, such as Homeric Greek , the name had been current in the singular form though, as Ἀθήνη ( Athḗnē ). It was possibly rendered in

Athens is also home to several museums and cultural institutions, such as the National Archeological Museum , featuring the world's largest collection of ancient Greek antiquities, the Acropolis Museum , the Museum of Cycladic Art , the Benaki Museum , and the Byzantine and Christian Museum . Athens was the host city of the first modern-day Olympic Games in 1896, and 108 years later it hosted

6996-634: The Early Modern period. John Philoponus (in Late antiquity ) and Galileo (in Early modern period ) are said to have shown by experiment that Aristotle's claim that a heavier object falls faster than a lighter object is incorrect. A contrary opinion is given by Carlo Rovelli , who argues that Aristotle's physics of motion is correct within its domain of validity, that of objects in the Earth 's gravitational field immersed in

7155-515: The Great Comet of 371 BC . Aristotle was one of the first people to record any geological observations. He stated that geological change was too slow to be observed in one person's lifetime. The geologist Charles Lyell noted that Aristotle described such change, including "lakes that had dried up" and "deserts that had become watered by rivers", giving as examples the growth of the Nile delta since

7314-471: The History of Animals in a graded scale of perfection, a nonreligious version of the scala naturae , with man at the top. His system had eleven grades of animal, from highest potential to lowest, expressed in their form at birth: the highest gave live birth to hot and wet creatures, the lowest laid cold, dry mineral-like eggs. Animals came above plants , and these in turn were above minerals. He grouped what

7473-639: The Ilisos and the Eridanos stream are the historical rivers of Athens. By the late 1970s, the pollution of Athens had become so destructive that according to the then Greek Minister of Culture , Constantine Trypanis, "...the carved details on the five the caryatids of the Erechtheum had seriously degenerated, while the face of the horseman on the Parthenon's west side was all but obliterated."

By the sixth century BC, widespread social unrest led to the reforms of Solon . These would pave the way for the eventual introduction of democracy by Cleisthenes in 508 BC. Athens had by this time become

Along with rest of Byzantine Greece, Athens was part of the series of feudal fiefs , similar to the Crusader states established in Syria and on Cyprus after the First Crusade . This period is known as the Frankokratia . The first Ottoman attack on Athens, which involved a short-lived occupation of the town, came in 1397, under

7950-538: The Macedonian capital, making his first connections with the Macedonian monarchy . At the age of seventeen or eighteen, Aristotle moved to Athens to continue his education at Plato's Academy . He became distinguished as a researcher and lecturer, earning for himself the nickname "mind of the school" by his tutor Plato . In Athens, he probably experienced the Eleusinian Mysteries as he wrote when describing

He also wrote descriptions of comets, including

8268-881: The Municipality of Athens (the City Centre) in virtually all directions. For the Athenians, all the urban municipalities surrounding the City Centre are called suburbs. According to their geographic location in relation to the City of Athens , the suburbs are divided into four zones; the northern suburbs (including Agios Stefanos , Dionysos , Ekali , Nea Erythraia , Kifissia , Kryoneri , Maroussi , Pefki , Lykovrysi , Metamorfosi , Nea Ionia , Nea Filadelfeia , Irakleio , Vrilissia , Melissia , Penteli , Chalandri , Agia Paraskevi , Gerakas , Pallini , Galatsi , Psychiko and Filothei );

8427-655: The Mycenaean civilization, and the Acropolis was the site of a major Mycenaean fortress, whose remains can be recognised from sections of the characteristic Cyclopean walls. Unlike other Mycenaean centers, such as Mycenae and Pylos , it is not known whether Athens suffered destruction in about 1200 BC, an event often attributed to a Dorian invasion, and the Athenians always maintained that they were pure Ionians with no Dorian element. However, Athens, like many other Bronze Age settlements , went into economic decline for around 150 years afterwards. Iron Age burials, in

The zoo is home to around 2000 animals representing 400 species, and is open 365 days a year. Smaller zoos exist within public gardens or parks, such as the zoo within the National Garden of Athens. Athens has a hot-summer Mediterranean climate ( Köppen climate classification : Csa ). The climate in Athens can be considered warmer than some cities that are similar or even less distant from

8745-508: The Physics (215a25), Aristotle effectively states a quantitative law, that the speed, v, of a falling body is proportional (say, with constant c) to its weight, W, and inversely proportional to the density, ρ, of the fluid in which it is falling:; Aristotle implies that in a vacuum the speed of fall would become infinite, and concludes from this apparent absurdity that a vacuum is not possible. Opinions have varied on whether Aristotle intended to state quantitative laws. Henri Carteron held

A shot fired during the bombardment of the Acropolis caused a powder magazine in the Parthenon to explode (26 September), and the building was severely damaged, giving it largely the appearance it has today. The Venetian occupation of Athens lasted for six months, and both the Venetians and the Ottomans participated in

9381-412: The universal . Aristotle's ontology places the universal ( katholou ) in particulars ( kath' hekaston ), things in the world, whereas for Plato the universal is a separately existing form which actual things imitate. For Aristotle, "form" is still what phenomena are based on, but is "instantiated" in a particular substance. Plato argued that all things have a universal form , which could be either

9540-513: The "extreme view" that Aristotle's concept of force was basically qualitative, but other authors reject this. Archimedes corrected Aristotle's theory that bodies move towards their natural resting places; metal boats can float if they displace enough water ; floating depends in Archimedes' scheme on the mass and volume of the object, not, as Aristotle thought, its elementary composition. Aristotle's writings on motion remained influential until

9699-421: The Athenians the first domesticated olive tree . Cecrops accepted this gift and declared Athena the patron goddess of Athens. Eight different etymologies, now commonly rejected, have been proposed since the 17th century. Christian Lobeck proposed as the root of the name the word ἄθος ( áthos ) or ἄνθος ( ánthos ) meaning "flower", to denote Athens as the "flowering city". Ludwig von Döderlein proposed

The route in its entirety provides visitors with views of

10653-541: The Good aim at freedom from disturbance; and the virtues would be productive of happiness." This testimony suggests that Speusippus' ethics may have been an important background to ethical ideas of the Stoics (the will's conformity with nature) and Epicureans (compare "freedom from disturbance," aochlēsia , with the notion of ataraxia ). Modern scholars have detected a polemic between Speusippus and Eudoxus of Cnidus concerning

In the second century AD, the Roman emperor Hadrian, himself an Athenian citizen, ordered the construction of a library, a gymnasium, an aqueduct which is still in use, several temples and sanctuaries, a bridge and financed

11130-602: The Greeks and a despot to the barbarians". Alexander's education under the guardianship of Aristotle likely lasted for only a few years, as at around the age of sixteen he returned to Pella and was appointed regent of Macedon by his father Philip. During this time, Aristotle is said to have gifted Alexander an annotated copy of the Iliad , which reportedly became one of Alexander's most prized possessions. Scholars speculate that two of Aristotle's now lost works, On kingship and On behalf of

11766-599: The Persians within one year, after a heroic but ultimately failed resistance at Thermopylae by Spartans and other Greeks led by King Leonidas , after both Boeotia and Attica fell to the Persians. The decades that followed became known as the Golden Age of Athenian democracy , during which time Athens became the leading city of Ancient Greece , with its cultural achievements laying the foundations for Western civilization . The playwrights Aeschylus , Sophocles and Euripides flourished in Athens during this time, as did

11925-699: The Persians, and philosophical questions, like the definition of braveness. A widespread speculation in antiquity suggested that Aristotle played a role in Alexander's death, but the only evidence of this is an unlikely claim made some six years after the death. Following Alexander's death, anti-Macedonian sentiment in Athens was rekindled. In 322 BC, Demophilus and Eurymedon the Hierophant reportedly denounced Aristotle for impiety, prompting him to flee to his mother's family estate in Chalcis, Euboea , at which occasion he

12084-487: The Soul and Poetics . Aristotle studied and made significant contributions to "logic, metaphysics, mathematics, physics, biology, botany, ethics, politics, agriculture, medicine, dance, and theatre." While Alexander deeply admired Aristotle, near the end of his life, the two men became estranged having diverging opinions over issues, like the optimal administration of city-states, the treatment of conquered populations, such as

12243-617: The absolute One, but it was not to be regarded as an existing entity, since all entities can only be the result of development. When, however, with the Pythagoreans , he reckoned the One in the series of good things, he probably conceived it only in its opposition to the Many , and wished to indicate that it was from the One and not from the Many , that the good and perfect is to be derived. Nevertheless, Speusippus seems to have attributed vital activity to

12402-544: The ancient monuments suffered badly. The Ottoman forces remained in possession until March 1833, when they withdrew. Following the Greek War of Independence and the establishment of the Greek Kingdom , Athens was chosen to replace Nafplio as the second capital of the newly independent Greek state in 1834, largely because of historical and sentimental reasons. At the time, after the extensive destruction it had suffered during

12561-424: The assumption of a perception, which, by participation in rational truth, raises itself to the rank of knowledge. By this he seems to have understood an immediate (in the first instance aesthetic) mode of conception; since he appealed, in support of this view, to the consideration that artistic skill has its foundation, not in sensuous activity, but in an unerring power of distinguishing between its objects, that is, in

12720-431: The authorities of the city throughout the 1990s resulted in the improvement of air quality; the appearance of smog (or nefos as the Athenians used to call it) has become less common. Measures taken by the Greek authorities throughout the 1990s have improved the quality of air over the Attica Basin. Nevertheless, air pollution still remains an issue for Athens, particularly during the hottest summer days. In late June 2007,

12879-489: The ball along to make it continue to rise even though the hand is no longer acting on it, resulting in the Medieval theory of impetus . Aristotle suggested that the reason for anything coming about can be attributed to four different types of simultaneously active factors. His term aitia is traditionally translated as "cause", but it does not always refer to temporal sequence; it might be better translated as "explanation", but

13038-399: The becoming is for the sake of the end; and the actuality is the end, and it is for the sake of this that the potentiality is acquired. For animals do not see in order that they may have sight, but they have sight that they may see. In summary, the matter used to make a house has potentiality to be a house and both the activity of building and the form of the final house are actualities, which

13197-400: The better gift would become their patron and appointed Cecrops , the king of Athens, as the judge. According to the account given by Pseudo-Apollodorus , Poseidon struck the ground with his trident and a salt water spring welled up. In an alternative version of the myth from Vergil 's poem Georgics , Poseidon instead gave the Athenians the first horse. In both versions, Athena offered

13356-574: The broad sense coextensive with reasoning, which he also would describe as "science". However, his use of the term science carries a different meaning than that covered by the term "scientific method". For Aristotle, "all science ( dianoia ) is either practical, poetical or theoretical" ( Metaphysics 1025b25). His practical science includes ethics and politics; his poetical science means the study of fine arts including poetry; his theoretical science covers physics, mathematics and metaphysics. In his On Generation and Corruption , Aristotle related each of

13515-433: The cause of earthquakes was a gas or vapor ( anathymiaseis ) that was trapped inside the earth and trying to escape, following other Greek authors Anaxagoras , Empedocles and Democritus . Aristotle also made many observations about the hydrologic cycle. For example, he made some of the earliest observations about desalination: he observed early – and correctly – that when seawater is heated, freshwater evaporates and that

13674-497: The city is much debated, but is generally taken to mark the end of the ancient history of Athens. Athens was sacked by the Slavs in 582, but remained in imperial hands thereafter, as highlighted by the visit of the emperor Constans II ( r.  641–668 ) in 662/3 and its inclusion in the Theme of Hellas . The city was threatened by Saracen raids in the 8th–9th centuries—in 896, Athens

13833-575: The city was sometimes referred to as the City of the Violet Crown , first documented in Pindar's ἰοστέφανοι Ἀθᾶναι ( iostéphanoi Athânai ), or as τὸ κλεινὸν ἄστυ ( tò kleinòn ásty , "the glorious city"). During the medieval period, the name of the city was rendered once again in the singular as Ἀθήνα . Variant names included Setines, Satine, and Astines, all derivations involving false splitting of prepositional phrases. King Alphonse X of Castile gives

13992-732: The city's infrastructure (including the Attiki Odos motorway, the expansion of the Athens Metro , and the new Athens International Airport ), considerably alleviated pollution and transformed Athens into a much more functional city. In 2004, Athens hosted the 2004 Summer Olympics . Athens sprawls across the central plain of Attica that is often referred to as the Athens Basin or the Attica Basin ( Greek : Λεκανοπέδιο Αθηνών/Αττικής , romanized :  Lekanopédio Athinón/Attikís ). The basin

14151-591: The city, in response of complaints of maladministration by the local governors. After her death, Athens came under the purview of the Kizlar Agha. The Turks began a practice of storing gunpowder and explosives in the Parthenon and Propylaea . In 1640, a lightning bolt struck the Propylaea, causing its destruction. In 1687, during the Morean War , the Acropolis was besieged by the Venetians under Francesco Morosini , and

14310-453: The city, represented by ancient monuments , and works of art, the most famous of all being the Parthenon , considered a key landmark of early Western culture . The city also retains Roman , Byzantine and a smaller number of Ottoman monuments, while its historical urban core features elements of continuity through its millennia of history. Athens is home to two UNESCO World Heritage Sites ,

14469-418: The city, where blizzards occur on a somewhat more regular basis. The most recent examples include the snowstorms of 16 February 2021 and 24 January 2022, when the entire urban area was blanketed in snow. Athens may get particularly hot in the summer, owing partly to the strong urban heat island effect characterizing the city. In fact, Athens is considered to be the hottest city in mainland Europe , and

14628-545: The city. Under Ottoman rule, Athens was denuded of any importance and its population severely declined, leaving it as a "small country town" ( Franz Babinger ). From the early 17th century, Athens came under the jurisdiction of the Kizlar Agha , the chief black eunuch of the Sultan's harem . The city had originally been granted by Sultan Ahmed I ( r.  1603–1617 ) to Basilica, one of his favourite concubines, who hailed from

14787-512: The city. Classical Athens was one of the most powerful city-states in ancient Greece . It was a centre for democracy, the arts, education and philosophy, and was highly influential throughout the European continent, particularly in Ancient Rome . For this reason, it is often regarded as the cradle of Western civilization and the birthplace of democracy in its own right independently from

14946-502: The city. Modern scholars now generally agree that the goddess takes her name from the city, because the ending - ene is common in names of locations, but rare for personal names. According to the ancient Athenian founding myth , Athena, the goddess of wisdom and war, competed against Poseidon , the God of the Seas, for patronage of the yet-unnamed city; they agreed that whoever gave the Athenians

15105-537: The city. The National Garden of Athens was completed in 1840 and is a green refuge of 15.5 hectares in the centre of the Greek capital. It is to be found between the Parliament and Zappeion buildings, the latter of which maintains its own garden of seven hectares. Parts of the City Centre have been redeveloped under a masterplan called the Unification of Archeological Sites of Athens , which has also gathered funding from

15264-492: The colder half of the year with the remaining rainfall falling sparsely, mainly during thunderstorms. Fog is rare in the city center, but somewhat more frequent in areas to the east, close to mount Hymettus . The southern section of the Athens metropolitan area (i.e., Elliniko , Athens Riviera ) lies in the transitional zone between Mediterranean ( Csa ) and hot semi-arid climate ( BSh ), with its port-city of Piraeus being

15423-560: The completion of the Temple of Olympian Zeus . In the early 4th century AD, the Eastern Roman Empire began to be governed from Constantinople , and with the construction and expansion of the imperial city, many of Athens's works of art were taken by the emperors to adorn it. The Empire became Christianized, and the use of Latin declined in favour of exclusive use of Greek ; in the Roman imperial period , both languages had been used. In

15582-410: The composite natural ones, the study of nature would be the primary kind of knowledge; but if there is some motionless independent thing, the knowledge of this precedes it and is first philosophy, and it is universal in just this way , because it is first. And it belongs to this sort of philosophy to study being as being, both what it is and what belongs to it just by virtue of being. Aristotle examines

15741-406: The concepts of substance ( ousia ) and essence ( to ti ên einai , "the what it was to be") in his Metaphysics (Book VII), and he concludes that a particular substance is a combination of both matter and form, a philosophical theory called hylomorphism . In Book VIII, he distinguishes the matter of the substance as the substratum , or the stuff of which it is composed. For example, the matter of

15900-399: The data to come to the theory of evolution . Aristotle's writings can seem to modern readers close to implying evolution, but while Aristotle was aware that new mutations or hybridizations could occur, he saw these as rare accidents. For Aristotle, accidents, like heat waves in winter, must be considered distinct from natural causes. He was thus critical of Empedocles's materialist theory of

16059-446: The derivation, and laying down, of the ideas of genera and species : for he was interested in what the various sciences had in common, and how they might be connected. Thus he furthered the threefold division of philosophy into Dialectics , Ethics , and Physics , for which Plato had laid the foundation, without losing sight of the mutual connection of these three branches of philosophy. Speusippus maintained that no one could arrive at

16218-450: The details of Aristotle's life are not well-established. The biographies written in ancient times are often speculative and historians only agree on a few salient points. Aristotle was born in 384 BC in Stagira , Chalcidice , about 55 km (34 miles) east of modern-day Thessaloniki . He was the son of Nicomachus , the personal physician of King Amyntas of Macedon , and Phaestis,

16377-458: The difference between the principles ( archai ) on which they are based. Thus he distinguished substances of number , of size, of soul , while Plato had referred them, as separate entities, to the ideal numbers. Speusippus made still more kinds of substance, beginning with the One, and assuming principles for each kind of substance, one for numbers, another for spatial magnitudes, and then another for

16536-480: The doctrine of numbers which we can see in the extracts of his treatise on the Pythagorean numbers. Diogenes Laertius' list of Speusippus' works includes titles on justice, friendship, pleasure, and wealth. Clement of Alexandria (fr. 77 Tarán) reports that Speusippus considered happiness to be "a state that is complete in those things that are in accordance with nature, a condition desired by all human beings, while

16695-486: The earliest study of formal logic, and his conception of it was the dominant form of Western logic until 19th-century advances in mathematical logic . Kant stated in the Critique of Pure Reason that with Aristotle, logic reached its completion. Most of Aristotle's work is probably not in its original form, because it was most likely edited by students and later lecturers. The logical works of Aristotle were compiled into

16854-550: The early 5th century. The sack of the city by the Herules in 267 and by the Visigoths under their king Alaric I ( r.  395–410 ) in 396, however, dealt a heavy blow to the city's fabric and fortunes, and Athens was henceforth confined to a small fortified area that embraced a fraction of the ancient city. The emperor Justinian I ( r.  527–565 ) banned the teaching of philosophy by pagans in 529, an event whose impact on

17013-417: The empire became increasingly anti-pagan, Athens became a provincial town and experienced fluctuating fortunes. The city remained an important center of learning, especially of Neoplatonism —with notable pupils including Gregory of Nazianzus , Basil of Caesarea and emperor Julian ( r.  355–363 )—and consequently a center of paganism. Christian items do not appear in the archaeological record until

17172-624: The ending of the first period of Iconoclasm at the Second Council of Nicaea in 787. A few years later, another Athenian, Theophano , became empress as the wife of Staurakios (r. 811–812). Invasion of the empire by the Turks after the Battle of Manzikert in 1071, and the ensuing civil wars, largely passed the region by and Athens continued its provincial existence unharmed. When the Byzantine Empire

17331-600: The equator such as Seoul, Melbourne, Buenos Aires, Cape Town and Norfolk (Virgina, US). According to the meteorological station near the city center which is operated by the National Observatory of Athens , the downtown area has simple mean annual temperature of 19.2 °C (66.6 °F) while parts of the urban agglomeration may reach up to 19.8 °C (67.6 °F), being affected by the urban heat island effect. Athens receives about 433.1 millimetres (17.05 in) of precipitation per year, largely concentrated during

17490-532: The fight against the Persians, the league soon turned into a vehicle for Athens's own imperial ambitions. The resulting tensions brought about the Peloponnesian War (431–404 BC), in which Athens was defeated by its rival Sparta. By the mid-4th century BC, the northern Greek kingdom of Macedon was becoming dominant in Athenian affairs. In 338 BC the armies of Philip II defeated an alliance of some of

17649-442: The first century AD editor who assembled various small selections of Aristotle's works to create the treatise we know by the name Metaphysics . Aristotle called it "first philosophy", and distinguished it from mathematics and natural science (physics) as the contemplative ( theoretikē ) philosophy which is "theological" and studies the divine. He wrote in his Metaphysics (1026a16): If there were no other independent things besides

17808-458: The first important public buildings of the new capital. In 1896, Athens hosted the first modern Olympic Games . During the 1920s a number of Greek refugees , expelled from Asia Minor after the Greco-Turkish War and Population exchange between Greece and Turkey , swelled Athens's population; nevertheless it was most particularly following World War II , and from the 1950s and 1960s, that

17967-533: The following. Brood size decreases with (adult) body mass, so that an elephant has fewer young (usually just one) per brood than a mouse. Lifespan increases with gestation period , and also with body mass, so that elephants live longer than mice, have a longer period of gestation, and are heavier. As a final example, fecundity decreases with lifespan, so long-lived kinds like elephants have fewer young in total than short-lived kinds like mice. Aristotle distinguished about 500 species of animals , arranging these in

18126-531: The forms as existing separately from the things that participate in them, Aristotle maintained that universals exist within each thing on which each universal is predicated. So, according to Aristotle, the form of apple exists within each apple, rather than in the world of the forms. Concerning the nature of change ( kinesis ) and its causes, as he outlines in his Physics and On Generation and Corruption ( 319b–320a), he distinguishes coming-to-be ( genesis , also translated as 'generation') from: Coming-to-be

18285-509: The four elements proposed earlier by Empedocles , earth , water , air , and fire , to two of the four sensible qualities, hot, cold, wet, and dry. In the Empedoclean scheme, all matter was made of the four elements, in differing proportions. Aristotle's scheme added the heavenly aether , the divine substance of the heavenly spheres , stars and planets. Aristotle describes two kinds of motion: "violent" or "unnatural motion", such as that of

18444-541: The good. Eudoxus also accepts that the Good will be that at which all people aim, but identifies this as pleasure, as opposed to Speusippus' exclusive focus on moral goods. Texts of Aristotle and Aulus Gellius suggest that Speusippus insisted that pleasure was not a good, but that the Good was "in between the opposites of pleasure and pain." It is possible that the dispute between Speusippus and Eudoxus influenced Plato's Philebus (esp. 53c–55a). Speusippus also seems to have developed further Plato's ideas of justice and of

18603-428: The ground, say) require more force to make them move; and objects pushed with greater force move faster. This would imply the equation incorrect in modern physics. Natural motion depends on the element concerned: the aether naturally moves in a circle around the heavens, while the 4 Empedoclean elements move vertically up (like fire, as is observed) or down (like earth) towards their natural resting places. In

18762-675: The growth of the town in general. However, this medieval prosperity was not to last. In 1204, the Fourth Crusade conquered Athens and the city was not recovered from the Latins before it was taken by the Ottoman Turks . It did not become Greek in government again until the 19th century. From 1204 until 1458, Athens was ruled by Latins in three separate periods, following the Crusades . The "Latins", or " Franks ", were western Europeans and followers of

18921-618: The head of the Lyceum, who in turn passed them down to Neleus of Scepsis in Asia Minor. There, the papers remained hidden for protection until they were purchased by the collector Apellicon . In the meantime, many copies of Aristotle's major works had already begun to circulate and be used in the Lyceum of Athens, Alexandria , and later in Rome . With the Prior Analytics , Aristotle is credited with

19080-484: The historians Herodotus and Thucydides , the physician Hippocrates , and the philosopher Socrates . Guided by Pericles , who promoted the arts and fostered democracy, Athens embarked on an ambitious building program that saw the construction of the Acropolis of Athens (including the Parthenon ), as well as empire-building via the Delian League . Originally intended as an association of Greek city-states to continue

19239-440: The image. According to Aristotle, spontaneity and chance are causes of some things, distinguishable from other types of cause such as simple necessity. Chance as an incidental cause lies in the realm of accidental things , "from what is spontaneous". There is also more a specific kind of chance, which Aristotle names "luck", that only applies to people's moral choices. In astronomy , Aristotle refuted Democritus 's claim that

19398-487: The last decade (particularly the plant built on the small island of Psytalia) have greatly improved water quality in the Saronic Gulf, and the coastal waters of Athens are now accessible again to swimmers. Parnitha National Park is punctuated by well-marked paths, gorges, springs, torrents and caves dotting the protected area. Hiking and mountain-biking in all four mountains are popular outdoor activities for residents of

19557-535: The later Roman period, Athens was ruled by the emperors continuing until the 13th century, its citizens identifying themselves as citizens of the Roman Empire (" Rhomaioi "). The conversion of the empire from paganism to Christianity greatly affected Athens, resulting in reduced reverence for the city. Ancient monuments such as the Parthenon, Erechtheion and the Hephaisteion (Theseion) were converted into churches. As

19716-493: The looting of the Parthenon. One of its western pediments was removed, causing even more damage to the structure. During the Venetian occupation, the two mosques of the city were converted into Catholic and Protestant churches, but on 9 April 1688 the Venetians abandoned Athens again to the Ottomans. In 1822, a Greek insurgency captured the city, but it fell to the Ottomans again in 1826 (though Acropolis held till June 1827). Again

19875-568: The major commercial port of Piraeus to the southernmost suburb of Varkiza for some 25 km (20 mi), is also connected to the City Centre by tram. In the northern suburb of Maroussi, the upgraded main Olympic Complex (known by its Greek acronym OAKA) dominates the skyline. The area has been redeveloped according to a design by the Spanish architect Santiago Calatrava , with steel arches, landscaped gardens, fountains, futuristic glass, and

20034-468: The modern zoologist would call vertebrates as the hotter "animals with blood", and below them the colder invertebrates as "animals without blood". Those with blood were divided into the live-bearing ( mammals ), and the egg-laying ( birds , reptiles , fish ). Those without blood were insects, crustacea (non-shelled – cephalopods, and shelled ) and the hard-shelled molluscs ( bivalves and gastropods ). He recognised that animals did not exactly fit into

20193-458: The most extreme example, receiving just 331.9 millimetres (13.07 in) per year. The areas to the south generally see less extreme temperature variations as their climate is moderated by the Saronic gulf . The northern part of the city (i.e., Kifissia ), owing to its higher elevation, features moderately lower temperatures and slightly increased precipitation year-round. The generally dry climate of

20352-568: The nearby town of Loutraki (accessible by car via the Athens – Corinth National Highway, or the Athens Suburban Railway ). The concept of a partner city is used under different names in different countries, but they mean the same thing, that two cities in different countries assist each other as partners. Athens has quite a number of partners, whether as a "twin", a "sister", or a "partner." The Municipality of Athens has an official population of 643,452 people (in 2021). According to

20511-404: The oceans are then replenished by the cycle of rainfall and river runoff ("I have proved by experiment that salt water evaporated forms fresh and the vapor does not when it condenses condense into sea water again.") Aristotle was the first person to study biology systematically, and biology forms a large part of his writings. He spent two years observing and describing the zoology of Lesbos and

20670-488: The plural later on, like those of Θῆβαι ( Thêbai ) and Μυκῆναι ( Μukênai ). The root of the word is probably not of Greek or Indo-European origin, and is possibly a remnant of the Pre-Greek substrate of Attica. In antiquity, it was debated whether Athens took its name from its patron goddess Athena ( Attic Ἀθηνᾶ , Athēnâ , Ionic Ἀθήνη , Athḗnē , and Doric Ἀθάνα , Athā́nā ) or Athena took her name from

20829-407: The poet Dante called him "the master of those who know". His works contain the earliest known formal study of logic, and were studied by medieval scholars such as Peter Abelard and Jean Buridan . Aristotle's influence on logic continued well into the 19th century. In addition, his ethics , although always influential, gained renewed interest with the modern advent of virtue ethics . In general,

20988-425: The population of the city exploded, and Athens experienced a gradual expansion. In the 1980s, it became evident that smog from factories and an ever-increasing fleet of automobiles, as well as a lack of adequate free space due to congestion, had evolved into the city's most important challenge. A series of anti-pollution measures taken by the city's authorities in the 1990s, combined with a substantial improvement of

21147-464: The primordial Unity, as inseparably belonging to it, probably in order to explain how it could grow, by a process of self-development, into the good, spirit, etc.; for spirit also he distinguished from the one, as well as from the good; and the good from pleasure and pain. Less worthy of notice is the attempt by Speusippus to find a more suitable expression for the material principle , the indefinite duality of Plato; and his Pythagorizing mode of treating

21306-476: The pseudo-etymology 'the one without death/ignorance'. In Ottoman Turkish, it was called آتينا ‎ Ātīnā , and in modern Turkish, it is Atina . The oldest known human presence in Athens is the Cave of Schist, which has been dated to between the 11th and 7th millennia BC. Athens has been continuously inhabited for at least 5,000 years (3000 BC). By 1400 BC, the settlement had become an important centre of

21465-453: The request of Philip II of Macedon , tutored his son Alexander the Great beginning in 343 BC. He established a library in the Lyceum, which helped him to produce many of his hundreds of books on papyrus scrolls . Though Aristotle wrote many treatises and dialogues for publication, only around a third of his original output has survived , none of it intended for publication. Aristotle provided

21624-537: The rest of Greece. In modern times, Athens is a large cosmopolitan metropolis and central to economic, financial, industrial, maritime, political and cultural life in Greece. It is a Beta (+) - status global city according to the Globalization and World Cities Research Network , and is one of the biggest economic centers in Southeastern Europe. It also has a large financial sector, and its port Piraeus

21783-414: The result of generated existence, or development, just as the seeds of plants and animals are not the fully formed plants or animals themselves. Speusippus [supposes] that supreme beauty and goodness are not present in the beginning, because the beginnings both of plants and of animals are causes, but beauty and completeness are in the effects of these. The ultimate principle he designated, like Plato, as

21942-433: The same certainty as experimental science, but it sets out testable hypotheses and constructs a narrative explanation of what is observed. In this sense, Aristotle's biology is scientific. From the data he collected and documented, Aristotle inferred quite a number of rules relating the life-history features of the live-bearing tetrapods (terrestrial placental mammals) that he studied. Among these correct predictions are

22101-439: The seed of a plant in the soil is potentially ( dynamei ) a plant, and if it is not prevented by something, it will become a plant. Potentially, beings can either 'act' ( poiein ) or 'be acted upon' ( paschein ), which can be either innate or learned. For example, the eyes possess the potentiality of sight (innate – being acted upon), while the capability of playing the flute can be possessed by learning (exercise – acting). Actuality

22260-690: The sights one viewed at the Mysteries, "to experience is to learn" ( παθεĩν μαθεĩν ). Aristotle remained in Athens for nearly twenty years before leaving in 348/47 BC after Plato's death. The traditional story about his departure records that he was disappointed with the Academy's direction after control passed to Plato's nephew Speusippus , although it is possible that the anti-Macedonian sentiments in Athens could have also influenced his decision. Aristotle left with Xenocrates to Assos in Asia Minor , where he

22419-438: The soul; and by going on in this way he multiplies the kinds of substance. Nevertheless, Speusippus also must have recognised something common in those different kinds of substances, inasmuch as, firstly, he set out from the absolute One, and regarded it as a formal principle which they had in common, and, secondly, he appears to have assumed that multitude and multiformity was a common primary element in their composition. But it

22578-689: The southern suburbs (including Alimos , Nea Smyrni , Moschato , Tavros , Agios Ioannis Renti , Kallithea , Piraeus , Agios Dimitrios , Palaio Faliro , Elliniko , Glyfada , Lagonisi , Saronida , Argyroupoli , Ilioupoli , Varkiza , Voula , Vari and Vouliagmeni ); the eastern suburbs (including Zografou , Dafni , Vyronas , Kaisariani , Cholargos and Papagou ); and the western suburbs (including Peristeri , Ilion , Egaleo , Koridallos , Agia Varvara , Keratsini , Perama , Nikaia , Drapetsona , Chaidari , Petroupoli , Agioi Anargyroi , Ano Liosia , Aspropyrgos , Eleusina , Acharnes and Kamatero ). The Athens city coastline, extending from

22737-543: The southern suburbs (such as Alimos , Palaio Faliro , Elliniko , Glyfada , Voula , Vouliagmeni and Varkiza ) known as the Athens Riviera , host a number of sandy beaches, most of which are operated by the Greek National Tourism Organisation and require an entrance fee. Casinos operate on both Mount Parnitha, some 25 km (16 mi) from downtown Athens (accessible by car or cable car), and

22896-440: The stem of the verb θάω , stem θη- ( tháō , thē- , "to suck") to denote Athens as having fertile soil. Athenians were called cicada -wearers (Ancient Greek: Τεττιγοφόροι ) because they used to wear pins of golden cicadas. A symbol of being autochthonous (earth-born), because the legendary founder of Athens, Erechtheus was an autochthon or of being musicians, because the cicada is a "musician" insect. In classical literature,

23055-747: The study of more complex forms, namely, syllogisms (in the Analytics ) and dialectics (in the Topics and Sophistical Refutations ). The first three treatises form the core of the logical theory stricto sensu : the grammar of the language of logic and the correct rules of reasoning. The Rhetoric is not conventionally included, but it states that it relies on the Topics . What is today called Aristotelian logic with its types of syllogism (methods of logical argument), Aristotle himself would have labelled "analytics". The term "logic" he reserved to mean dialectics . The word "metaphysics" appears to have been coined by

23214-549: The surrounding seas, including in particular the Pyrrha lagoon in the centre of Lesbos. His data in History of Animals , Generation of Animals , Movement of Animals , and Parts of Animals are assembled from his own observations, statements given by people with specialized knowledge, such as beekeepers and fishermen, and less accurate accounts provided by travellers from overseas. His apparent emphasis on animals rather than plants

23373-470: The time of Homer , and "the upheaving of one of the Aeolian islands , previous to a volcanic eruption ."' Meteorologica lends its name to the modern study of meteorology, but its modern usage diverges from the content of Aristotle's ancient treatise on meteors . The ancient Greeks did use the term for a range of atmospheric phenomena, but also for earthquakes and volcanic eruptions. Aristotle proposed that

23532-416: The time when he accompanied his uncle Plato on his third journey to Syracuse (Italy), where he displayed considerable ability and prudence, especially in his amicable relations with Dion . His moral worth is recognised even by Timon , though only that he may heap the more unsparing ridicule on his intellect. The report about his sudden fits of anger, his greed, and his debauchery, are probably derived from

23691-664: The town became an important centre for the production of soaps and dyes. The growth of the town attracted the Venetians , and various other traders who frequented the ports of the Aegean, to Athens. This interest in trade appears to have further increased the economic prosperity of the town. The 11th and 12th centuries were the Golden Age of Byzantine art in Athens. Almost all of the most important Middle Byzantine churches in and around Athens were built during these two centuries, and this reflects

23850-473: The traditional rendering will be employed here. Aristotle describes experiments in optics using a camera obscura in Problems , book 15. The apparatus consisted of a dark chamber with a small aperture that let light in. With it, he saw that whatever shape he made the hole, the sun's image always remained circular. He also noted that increasing the distance between the aperture and the image surface magnified

24009-400: The war of independence, it was reduced to a town of about 4,000 people (less than half its earlier population) in a loose swarm of houses along the foot of the Acropolis. The first King of Greece , King Otto of Bavaria, commissioned the architects Stamatios Kleanthis and Eduard Schaubert to design a modern city plan fit for the capital of a state. The first modern city plan consisted of

24168-485: Was an Ancient Greek philosopher and polymath . His writings cover a broad range of subjects spanning the natural sciences , philosophy , linguistics , economics , politics , psychology , and the arts . As the founder of the Peripatetic school of philosophy in the Lyceum in Athens , he began the wider Aristotelian tradition that followed, which set the groundwork for the development of modern science . Little

24327-413: Was invited by his former fellow student Hermias of Atarneus ; he stayed there for a few years and left around the time of Hermias' death. While at Assos, Aristotle and his colleague Theophrastus did extensive research in botany and marine biology , which they later continued at the near-by island of Lesbos . During this time, Aristotle married Pythias , Hermias's adoptive daughter and niece, and had

24486-766: Was not replaced systematically until the Enlightenment and theories such as classical mechanics were developed. He influenced Judeo-Islamic philosophies during the Middle Ages, as well as Christian theology , especially the Neoplatonism of the Early Church and the scholastic tradition of the Catholic Church . Aristotle was revered among medieval Muslim scholars as "The First Teacher", and among medieval Christians like Thomas Aquinas as simply "The Philosopher", while

24645-420: Was raided and possibly occupied for a short period, an event which left some archaeological remains and elements of Arabic ornamentation in contemporary buildings —but there is also evidence of a mosque existing in the city at the time. In the great dispute over Byzantine Iconoclasm , Athens is commonly held to have supported the iconophile position, chiefly due to the role played by Empress Irene of Athens in

24804-511: Was recorded in the areas of Elefsina and Tatoi on 10 July 1977. Athens became the capital of Greece in 1834, following Nafplion , which was the provisional capital from 1829. The municipality (city) of Athens is also the capital of the Attica region. The term Athens can refer either to the municipality of Athens, to Greater Athens or urban area, or to the entire Athens Metropolitan Area. The large city centre ( Greek : Κέντρο της Αθήνας , romanized :  Kéntro tis Athínas ) of

24963-432: Was rescued by the resolute leadership of the three Komnenos emperors Alexios , John and Manuel , Attica and the rest of Greece prospered. Archaeological evidence tells us that the medieval town experienced a period of rapid and sustained growth, starting in the 11th century and continuing until the end of the 12th century. The Agora (marketplace) had been deserted since late antiquity, began to be built over, and soon

25122-461: Was said to have stated "I will not allow the Athenians to sin twice against philosophy" – a reference to Athens's trial and execution of Socrates . He died in Chalcis, Euboea of natural causes later that same year, having named his student Antipater as his chief executor and leaving a will in which he asked to be buried next to his wife. Aristotle left his works to Theophrastus, his successor as

25281-588: Was widely disbelieved until the 19th century. He gives accurate descriptions of the four-chambered fore-stomachs of ruminants , and of the ovoviviparous embryological development of the hound shark . He notes that an animal's structure is well matched to function so birds like the heron (which live in marshes with soft mud and live by catching fish) have a long neck, long legs, and a sharp spear-like beak, whereas ducks that swim have short legs and webbed feet. Darwin , too, noted these sorts of differences between similar kinds of animal, but unlike Aristotle used
