Accordingly, they shaped their entire lives in accordance with their interpretations of astral configurations and phenomena. The Hellenistic schools of philosophical skepticism criticized the rationality of astrology. Criticism of astrology by academic skeptics such as Cicero , Carneades , and Favorinus ; and Pyrrhonists such as Sextus Empiricus has been preserved. Carneades argued that belief in fate denies free will and morality ; that people born at different times can all die in

The inventions employ innovative engineering ideas, such as automatic one-way and two-way valves , mechanical memories, devices capable of responding to feedback , and delay mechanisms. Most of them were operated by water pressure . The trick vessels are unimportant in themselves; their significance for historians of engineering

11625-474: The Persian settlers that were moved from Hyrcania . Similarly near Sardis, there was the plain of Cyrus, which further signified the presence of numerous Persian settlements in the area. In all these centuries, Lydia and Pontus were reportedly the chief centers for the worship of the Persian gods in Asia Minor. According to Pausanias , as late as the second century AD, one could witness rituals which resembled
11780-459: The Persians is eclectic and has included contributions from both the east and the west. Due to the central location of Iran, Persian art has served as a fusion point between eastern and western traditions. Persians have contributed to various forms of art, including calligraphy , carpet weaving , glasswork , lacquerware , marquetry ( khatam ), metalwork , miniature illustration , mosaic , pottery , and textile design . The Persian language
11935-500: The Persians and the Kurds . They speak various dialects of the Luri language , which is considered to be a descendant of Middle Persian . The Hazaras , making up the third largest ethnic group in Afghanistan, speak a variety of Persian by the name of Hazaragi , which is more precisely a part of the Dari dialect continuum. The Aimaqs , a semi-nomadic people native to Afghanistan, speak
12090-552: The Persians took the name. Apparently, the Persians themselves knew the story, as Xerxes I tried to use it to suborn the Argives during his invasion of Greece, but ultimately failed to do so. Although Persis (Persia proper) was only one of the provinces of ancient Iran, varieties of this term (e.g., Persia ) were adopted through Greek sources and used as an exonym for all of the Persian Empire for many years. Thus, especially in
12245-940: The Sasanian Empire includes, among others, castle fortifications such as the Fortifications of Derbent (located in North Caucasus , now part of Russia ), the Rudkhan Castle and the Shapur-Khwast Castle , palaces such as the Palace of Ardashir and the Sarvestan Palace , bridges such as the Shahrestan Bridge and the Shapuri Bridge , the Archway of Ctesiphon , and the reliefs at Taq-e Bostan . Architectural elements from
12400-624: The Western esoteric tradition. Tanya Luhrmann has said that "all magicians know something about astrology," and refers to a table of correspondences in Starhawk's The Spiral Dance , organised by planet , as an example of the astrological lore studied by magicians. The earliest Vedic text on astronomy is the Vedanga Jyotisha ; Vedic thought later came to include astrology as well. Hindu natal astrology originated with Hellenistic astrology by
12555-457: The Will of God can be known and predicted. For example, Avicenna's 'Refutation against astrology', Risāla fī ibṭāl aḥkām al-nojūm , argues against the practice of astrology while supporting the principle that planets may act as agents of divine causation. Avicenna considered that the movement of the planets influenced life on earth in a deterministic way, but argued against the possibility of determining
12710-406: The apparent positions of celestial objects . Different cultures have employed forms of astrology since at least the 2nd millennium BCE, these practices having originated in calendrical systems used to predict seasonal shifts and to interpret celestial cycles as signs of divine communications. Most, if not all, cultures have attached importance to what they observed in the sky, and some—such as
12865-446: The caliphs for different civil engineering projects, including their involvement in the building of the city of al-D̲j̲aʿfariyya for al-Mutawakki, led to them becoming involved in court politics. In 860, the Banū Mūsā and Mutawakkil’s architects were involved in obtaining land for a new city. The caliph’s advisor suggested that Muhammed and Ahmad bin Musa should be forced to contribute towards
13020-404: The carpet production in the city of Sardis, stating that the locals take pride in their carpet production. A special mention of Persian carpets is also made by Athenaeus of Naucratis in his Deipnosophistae , as he describes a "delightfully embroidered" Persian carpet with "preposterous shapes of griffins ". The Pazyryk carpet, a Scythian pile-carpet dating back to the 4th century BC that
13175-427: The city of Samarra . To calculate the difference in latitude between Samarra and Nishapur , they organized simultaneous observations of a lunar eclipse . Whilst working for al-Ma’mun, the Banū Mūsā travelled to a desert near Sanjar , in northern Mesopotamia , with the aim of measuring the length of a degree of latitude along a meridian , and from that verifying a value of 25,000 miles (40,000 km) obtained by
13330-498: The concepts of area and circumference , giving them numerical values rather than considering them in terms of ratios . The most important of the works produced by the Banū Mūsā was the Kitāb maʻrifat masāḥat al-ashkāl al-basīṭah wa-al-kurīyah (" Book on the Measurement of Plane and Spherical Figures "), of which a commentary was made by the persian polymath Naṣīr al-Dīn al-Ṭūsī in
13485-564: The death of her husband, king Henry II of France made by her astrologer Lucus Gauricus. Major astronomers who practised as court astrologers included Tycho Brahe in the royal court of Denmark, Johannes Kepler to the Habsburgs , Galileo Galilei to the Medici , and Giordano Bruno who was burnt at the stake for heresy in Rome in 1600. The distinction between astrology and astronomy was not entirely clear. Advances in astronomy were often motivated by
13640-493: The desire to improve the accuracy of astrology. Kepler, for example, was driven by a belief in harmonies between Earthly and celestial affairs, yet he disparaged the activities of most astrologers as "evil-smelling dung". Ephemerides with complex astrological calculations, and almanacs interpreting celestial events for use in medicine and for choosing times to plant crops, were popular in Elizabethan England. In 1597,
13795-546: The development of psychological astrology . Advocates have defined astrology as a symbolic language, an art form, a science , and a method of divination. Though most cultural astrology systems share common roots in ancient philosophies that influenced each other, many use methods that differ from those in the West. These include Hindu astrology (also known as "Indian astrology" and in modern times referred to as "Vedic astrology") and Chinese astrology, both of which have influenced
13950-474: The earliest scholars to adopt Greek mathematics , but innovative in their approach to the concepts of area and circumference by expressing them using numerical values instead of ratios . They made geodesic measurements to determine the length of a degree of latitude , and so obtained a relatively accurate value for the circumference of the Earth . The Banū Mūsā wrote almost 20 books, all but three of which are now lost. The most important of all their works
14105-431: The exact influence of the stars. Essentially, Avicenna did not deny the core dogma of astrology, but denied our ability to understand it to the extent that precise and fatalistic predictions could be made from it. Ibn Qayyim al-Jawziyya (1292–1350), in his Miftah Dar al-SaCadah , also used physical arguments in astronomy to question the practice of judicial astrology. He recognised that the stars are much larger than
14260-601: The expansion of the Persianate societies , particularly those of Turco-Persian and Indo-Persian blends. After over eight centuries of foreign rule within the region, the Iranian hegemony was reestablished by the emergence of the Safavid Empire in the 16th century. Under the Safavid Empire, focus on Persian language and identity was further revived, and the political evolution of the empire once again maintained Persian as
14415-405: The expense of a new palace nearby. The peak of Muhammad's political activity came towards the end of his life, when Turkish commanders were starting to take control of the state. After the death of al-Mutawakkil, Muhammad helped al-Mustaʿīn to become nominated as caliph. Denied the throne, Al-Mustaʿīn's brother besieged Baghdad, and Muhammad was sent to estimate the size of the attacking army. After
14570-454: The failure of astrology to explain twins who behave differently although conceived at the same moment and born at approximately the same time. Some of the practices of astrology were contested on theological grounds by medieval Muslim astronomers such as Al-Farabi (Alpharabius), Ibn al-Haytham (Alhazen) and Avicenna . They said that the methods of astrologers conflicted with orthodox religious views of Islamic scholars , by suggesting that
14725-559: The fall of the Sassanian Empire . They have had a significant role in the development of India , Pakistan and Sri Lanka , and also played a role in the development of Iranian nationalism during the late Qajar years and Pahlavi dynasty. They are primarily located in the western regions of India principally the states of Gujarat and Maharashtra , with smaller communities in other parts of India and in South and Southeast Asia. They speak
14880-643: The fall of the Achaemenid Persian Empire, records only traces of Persians in western Asia Minor; however, he considered Cappadocia "almost a living part of Persia". The Iranian dominance collapsed in 330 BC following the conquest of the Achaemenid Empire by Alexander the Great , but reemerged shortly after through the establishment of the Parthian Empire in 247 BC, which was founded by a group of ancient Iranian people rising from Parthia . Until
15035-542: The familiar elements of traditional Chinese culture – the Yin-Yang philosophy, theory of the five elements, Heaven and Earth, Confucian morality – were brought together to formalise the philosophical principles of Chinese medicine and divination, astrology, and alchemy . The ancient Arabs that inhabited the Arabian Peninsula before the advent of Islam used to profess a widespread belief in fatalism ( ḳadar ) alongside
15190-484: The famous works of medieval Persian literature. A thriving contemporary Persian literature has also been formed by the works of writers such as Ahmad Shamlou , Forough Farrokhzad , Mehdi Akhavan-Sales , Parvin E'tesami , Sadegh Hedayat , and Simin Daneshvar , among others. Not all Persian literature is written in Persian, as works written by Persians in other languages—such as Arabic and Greek—might also be included. At
15345-534: The fifteenth century. In Paradiso , the final part of the Divine Comedy , the Italian poet Dante Alighieri referred "in countless details" to the astrological planets, though he adapted traditional astrology to suit his Christian viewpoint, for example using astrological thinking in his prophecies of the reform of Christendom . John Gower in the fourteenth century defined astrology as essentially limited to
15500-562: The first day of the fifth month in the Thai lunar calendar , or during the Songkran festival (now celebrated every 13–15 April), depending on the purpose of the use. Augustine (354–430) believed that the determinism of astrology conflicted with the Christian doctrines of man's free will and responsibility, and God not being the cause of evil, but he also grounded his opposition philosophically, citing
15655-692: The first time after two centuries of no attestation of the language, now having received the Arabic script and a large Arabic vocabulary. Persian language and culture continued to prevail after the invasions and conquests by the Mongols and the Turks (including the Ilkhanate , Ghaznavids , Seljuks , Khwarazmians , and Timurids ), who were themselves significantly Persianized , further developing in Asia Minor , Central Asia , and South Asia , where Persian culture flourished by
15810-536: The gods revealed to him in a dream the constellations that would be most favourable for the planned construction of a temple. However, there is controversy about whether these were genuinely recorded at the time or merely ascribed to ancient rulers by posterity. The oldest undisputed evidence of the use of astrology as an integrated system of knowledge is therefore attributed to the records of the first dynasty of Babylon (1950–1651 BCE). This astrology had some parallels with Hellenistic Greek (western) astrology, including
15965-428: The good and beautiful things that the soil produce." The Persian garden , the earliest examples of which were found throughout the Achaemenid Empire, has an integral position in Persian architecture. Gardens assumed an important place for the Achaemenid monarchs, and utilized the advanced Achaemenid knowledge of water technologies, including aqueducts , earliest recorded gravity-fed water rills, and basins arranged in
16120-525: The human body adherents believed were governed by the planets and signs. While Hood's presentation was innovative, his astrological information was largely standard and was taken from Gerard Mercator's astrological disc made in 1551, or a source used by Mercator. Despite its popularity, Renaissance astrology had what historian Gabor Almasi calls "elite debate", exemplified by the polemical letters of Swiss physician Thomas Erastus who fought against astrology, calling it "vanity" and "superstition." Then around
16275-469: The languages that are closely related to Persian . The ancient Persians were originally an ancient Iranian people who had migrated to the region of Persis (corresponding to the modern-day Iranian province of Fars ) by the 9th century BCE. Together with their compatriot allies, they established and ruled some of the world's most powerful empires that are well-recognized for their massive cultural, political, and social influence, which covered much of
16430-406: The last Wednesday of the preceding year in the Iranian calendar and last on the 13th day of the new year. Islamic festivals are also widely celebrated by Muslim Persians. Astrologer Astrology is a range of divinatory practices, recognized as pseudoscientific since the 18th century, that propose that information about human affairs and terrestrial events may be discerned by studying
16585-598: The main language of the country. During the times of the Safavids and subsequent modern Iranian dynasties such as the Qajars , architectural and iconographic elements from the time of the Sasanian Persian Empire were reincorporated, linking the modern country with its ancient past. Contemporary embracement of the legacy of Iran's ancient empires, with an emphasis on the Achaemenid Persian Empire, developed particularly under
16740-503: The making of predictions. The influence of the stars was in turn divided into natural astrology, with for example effects on tides and the growth of plants, and judicial astrology, with supposedly predictable effects on people. The fourteenth-century sceptic Nicole Oresme however included astronomy as a part of astrology in his Livre de divinacions . Oresme argued that current approaches to prediction of events such as plagues, wars, and weather were inappropriate, but that such prediction
16895-522: The mathematician and translator Hunayn ibn Ishaq , who became a close friend of one of the brothers, Muhammad. Of the translators, three were paid about 500 dinars a month. None of the brothers were medically trained, and relied upon Ishaq bin Hunayn and Thabit bin Qurra to translate Greek medical works. They exchanged ideas with other experts, including the astrologer Abu Ma'shar al-Balkhi , with whom Muhammed
17050-488: The modern period. One of those inventions includes an automatic flute player that may have been the first programmable machine or computer. Moḥammad, Aḥmad, and Ḥasan were the three sons of Mūsā ibn Shākir . They are always listed in sources in what is assumed by scholars to be their order of seniority. Musa was A Persian from Khorasan and a well-known Astronomer, al-Ma'mun , a son of the Abbasid caliph Harun al-Rashid who
17205-441: The neighboring Greek city states and the kingdom of Macedon , and later throughout the medieval Islamic world , all the way to modern Iran and others parts of Eurasia , Persian culture has been extended, celebrated, and incorporated. This is due mainly to its geopolitical conditions, and its intricate relationship with the ever-changing political arena once as dominant as the Achaemenid Empire. The artistic heritage of
17360-426: The occupation by Alexander the Great in 332 BCE, Egypt became Hellenistic . The city of Alexandria was founded by Alexander after the conquest, becoming the place where Babylonian astrology was mixed with Egyptian Decanic astrology to create Horoscopic astrology . This contained the Babylonian zodiac with its system of planetary exaltations , the triplicities of the signs and the importance of eclipses. It used
17515-560: The pervasive influence of Chaldeans, saying, "Still more trusted are the Chaldaeans; every word uttered by the astrologer they will believe has come from Hammon's fountain." One of the first astrologers to bring Hermetic astrology to Rome was Thrasyllus , astrologer to the emperor Tiberius , the first emperor to have had a court astrologer, though his predecessor Augustus had used astrology to help legitimise his Imperial rights. The main texts upon which classical Indian astrology
17670-421: The primary language of the subject peoples throughout their empire, sometimes by force, further confirming the new political reality over the region. The Arabic term ʿAjam , denoting "people unable to speak properly", was adopted as a designation for non-Arabs (or non-Arabic speakers), especially the Persians. Although the term had developed a derogatory meaning and implied cultural and ethnic inferiority, it
17825-531: The publication of sermons that depicted astrology as a legitimate biblical pursuit for Christians. They commissioned sermons that argued Astrology was divine, Hebraic, and scripturally supported by Bible passages about the Magi and the sons of Seth . According to historian Michelle Pfeffer, "The society's public relations campaign ultimately failed." Modern historians have mostly neglected the Society of Astrologers in favor of
17980-437: The reign of al-Mutawakkil, who was interested in mechanics, and asked the Banū Mūsā to write on this subject. A son of al-Mu'tasim was educated by Ahmad, but the brothers' relations with the caliph are otherwise unknown. When close to death, al-Mu'tasim's successor al-Wathiq called together his astrologers, including Muhammed, who erroneously pronounced that the caliph would live for another 50 years. The Banū Mūsā's employment by
18135-484: The reign of the Pahlavi dynasty , providing the motive of a modern nationalistic pride. Iran's modern architecture was then inspired by that of the country's classical eras, particularly with the adoption of details from the ancient monuments in the Achaemenid capitals Persepolis and Pasargadae and the Sasanian capital Ctesiphon . Fars, corresponding to the ancient province of Persia, with its modern capital Shiraz , became
18290-591: The rest of Asia Minor were cut off from their co-religionists in Iran proper, but they continued to practice the Iranian faith of their forefathers. Strabo, who observed them in the Cappadocian Kingdom in the first century BC, records (XV.3.15) that these "fire kindlers" possessed many "holy places of the Persian Gods", as well as fire temples. Strabo, who wrote during the time of Augustus ( r. 27 BC – AD 14 ), almost three hundred years after
18445-529: The same accident or battle; and that contrary to uniform influences from the stars, tribes and cultures are all different. Cicero , in De Divinatione , leveled a critique of astrology that some modern philosophers consider to be the first working definition of pseudoscience and the answer to the demarcation problem . Philosopher of Science Massimo Pigliucci , building on the work of Historian of Science, Damien Fernandez-Beanato, argues that Cicero outlined
18600-426: The same time, not all literature written in Persian is written by ethnic Persians or Iranians, as Turkic, Caucasian, and Indic authors have also used Persian literature in the environment of Persianate cultures . The most notable examples of ancient Persian architecture are the works of the Achaemenids hailing from Persis . Achaemenid architecture , dating from the expansion of the empire around 550 BC, flourished in
18755-415: The same time. Luther also compared astrologers to those who say their dice will always land on a certain number. Although the dice may roll on the number a couple of times, the predictor is silent for all the times the dice fails to land on that number. What is done by God, ought not to be ascribed to the stars. The upright and true Christian religion opposes and confutes all such fables. The Catechism of
18910-520: The second half of the 17th century, the Society of Astrologers (1647–1684), a trade, educational, and social organization, sought to unite London's often fractious astrologers in the task of revitalizing astrology. Following the template of the popular "Feasts of Mathematicians" they endeavored to defend their art in the face of growing religious criticism. The Society hosted banquets, exchanged "instruments and manuscripts", proposed research projects, and funded
19065-450: The siege, he was sent to find out the terms for al-Mustaʿīn to abdicate. It was during the reigns of al-Wathiq and al-Mutawakkil that internal rivalries arose between the scholars there. The Banū Mūsā became enemies of al-Kindi, and assisted in his persecution by al-Mutawakkil. They criticized and ridiculed his treatise on the astrolabe , and caused al-Mutawakkil to have him beaten, removed from court, and his library confiscated. The library
19220-508: The soul. The thirteenth century mathematician Campanus of Novara is said to have devised a system of astrological houses that divides the prime vertical into 'houses' of equal 30° arcs, though the system was used earlier in the East. The thirteenth century astronomer Guido Bonatti wrote a textbook, the Liber Astronomicus , a copy of which King Henry VII of England owned at the end of
19375-521: The stars. Scattered evidence suggests that the oldest known astrological references are copies of texts made in the ancient world. The Venus tablet of Ammisaduqa is thought to have been compiled in Babylon around 1700 BCE. A scroll documenting an early use of electional astrology is doubtfully ascribed to the reign of the Sumerian ruler Gudea of Lagash ( c. 2144 – 2124 BCE). This describes how
19530-733: The stars. The Korean zodiac is identical to the Chinese one. The Vietnamese zodiac is almost identical to the Chinese, except for second animal being the Water Buffalo instead of the Ox , and the fourth animal the Cat instead of the Rabbit . The Japanese have since 1873 celebrated the beginning of the new year on 1 January as per the Gregorian calendar . The Thai zodiac begins, not at Chinese New Year , but either on
19685-443: The still extant Royal Society (1660), even though both organizations initially had some of the same members. Astrology saw a popular revival starting in the 19th century, as part of a general revival of spiritualism and—later, New Age philosophy, and through the influence of mass media such as newspaper horoscopes. Early in the 20th century the psychiatrist Carl Jung developed some concepts concerning astrology, which led to
19840-508: The territory and population of the ancient world . Throughout history, the Persian people have contributed greatly to art and science . Persian literature is one of the world's most prominent literary traditions. In contemporary terminology, people from Afghanistan , Tajikistan , and Uzbekistan who natively speak the Persian language are known as Tajiks , with the former two countries having their own dialects of Persian known as Dari and Tajiki , respectively; whereas those in
19995-544: The three brothers studied geometry , mechanics , music, mathematics and astronomy , trained by a senior court astrologer , Yaḥyā bin Abī Manṣūr . The Banū Mūsā assisted al-Ma'mun's in his obsession to obtain and translate works from Greek into Arabic . They sent for Greek texts from the Byzantines , or travelled themselves to Byzantium to acquire them. During their working lives they used their wealth and energy towards
20150-458: The three orphaned children were cared for at the court of al-Maʾmūn, who made the senior Baghdad official Ishaq ibn Ibrahim al-Mus'abi their guardian. Al-Ma’mun recognized their abilities, and enrolled them in the House of Wisdom , an institution created by him as a centre for collecting, translating and studying books from other lands. In Baghdad, where they apparently lived for the rest of their lives,
20305-549: The time of Iran's ancient Persian empires have been adopted and incorporated in later period. They were used especially during the modernization of Iran under the reign of the Pahlavi dynasty to contribute to the characterization of the modern country with its ancient history. Xenophon , in his Oeconomicus , states: "The Great King [Cyrus II]...in all the districts he resides in and visits, takes care that there are parádeisos ("paradise") as they [Persians] call them, full of
20460-479: The time of the new star of 1572 and the comet of 1577 there began what Almasi calls an "extended epistemological reform" which began the process of excluding religion, astrology and anthropocentrism from scientific debate. By 1679, the yearly publication La Connoissance des temps eschewed astrology as a legitimate topic. During the Enlightenment , intellectual sympathy for astrology fell away, leaving only
20615-439: The total chart. The horoscope visually expresses the set of relationships for the time and place of the chosen event. These relationships are between the seven 'planets', signifying tendencies such as war and love; the twelve signs of the zodiac; and the twelve houses. Each planet is in a particular sign and a particular house at the chosen time, when observed from the chosen place, creating two kinds of relationship. A third kind
20770-406: The translation of these works. On his way home to Baghdad from Byzantium, Muhammad met and recruited Thābit ibn Qurra , a money changer from Harran . Thābit went on to make important discoveries in algebra, geometry, and astronomy. Under the direction of al-Ma'mun, the Banū Mūsā worked with the most talented men available, including al-Khwarizmi , al-Kindi , Al-Ḥajjāj ibn Yūsuf ibn Maṭar , and
20925-471: The west to the Indus Valley in the east, making it the largest empire the world had yet seen. The Achaemenids developed the infrastructure to support their growing influence, including the establishment of the cities of Pasargadae and Persepolis . The empire extended as far as the limits of the Greek city states in modern-day mainland Greece , where the Persians and Athenians influenced each other in what
21080-525: The western world, and common belief in it largely declined, until a continuing resurgence starting in the 1960s. The word astrology comes from the early Latin word astrologia , which derives from the Greek ἀστρολογία —from ἄστρον astron ("star") and -λογία -logia , ("study of"—"account of the stars"). The word entered the English language via Latin and medieval French , and its use overlapped considerably with that of astronomy (derived from
21235-448: The work to Fargftani. The caliph discovered that, due to an engineering error, once built, the water in the canal would drain away. He decreed that the brothers would be crucified beside the canal if this happened. Sanad bin Ah', who was the caliph's consultant engineer , agreed to proclaim—four months before the truth was to be revealed, and knowing that astrologers had predicted that the caliph
21390-692: The works of poets such as Dante Alighieri and Geoffrey Chaucer , and of playwrights such as Christopher Marlowe and William Shakespeare . Throughout most of its history, astrology was considered a scholarly tradition. It was accepted in political and academic contexts, and was connected with other studies, such as astronomy , alchemy , meteorology , and medicine. At the end of the 17th century, new scientific concepts in astronomy and physics (such as heliocentrism and Newtonian mechanics ) called astrology into question. Astrology thus lost its academic and theoretical standing, and common belief in astrology has largely declined. Astrology, in its broadest sense,
21545-426: The world's cultural history. Western astrology is a form of divination based on the construction of a horoscope for an exact moment, such as a person's birth. It uses the tropical zodiac, which is aligned to the equinoctial points . Western astrology is founded on the movements and relative positions of celestial bodies such as the Sun, Moon and planets, which are analysed by their movement through signs of
21700-731: Was a treatise on geometry , Kitāb Maʿrifah masāḥat al-ashkāl al-basīṭah wa-al-kuriyyah (" Book on the Measurement of Plane and Spherical Figures "), which was used extensively by medieval mathematicians. Their most famous extant work (of which the oldest and most reliable copy is in the Topkapi Sarayi in Istanbul ) is Kitab al-Hiyal al-Naficah (" Book of Ingenious Devices "). It describes 100 inventions, many of which were pouring vessels, intended to entertain party guests. Some of their innovations, such as those that involved fluid pressure variations and valves , remained unsurpassed until
21855-415: Was a valid field of inquiry. However, he attacked the use of astrology to choose the timing of actions (so-called interrogation and election) as wholly false, and rejected the determination of human action by the stars on grounds of free will. The friar Laurens Pignon (c. 1368–1449) similarly rejected all forms of divination and determinism, including by the stars, in his 1411 Contre les Devineurs . This
22010-440: Was a well-known Astronomer of al-Ma'mun , a son of the Abbasid caliph Harun al-Rashid . After their father's death, the brothers received an education under al-Ma'mun’s direction, and were enrolled at the House of Wisdom in Baghdad. There they undertook the translation of ancient Greek works acquired from Byzantium , which they used to develop their own technological, mathematical and astronomical ideas. They were some of
22165-530: Was absurd to link human attributes with myths about the signs of the zodiac, and wrote an entire book, Against the Astrologers (Πρὸς ἀστρολόγους, Pros astrologous ), compiling arguments against astrology. Against the Astrologers was the fifth section of a larger work arguing against philosophical and scientific inquiry in general, Against the Professors (Πρὸς μαθηματικούς, Pros mathematikous ). Plotinus ,
22320-694: Was an expert on mathematics and astronomy, Ahmad excelled in technology, and al-Hasan on mathematics. Muhammed knew the works of both Euclid and Ptolemy, and was considered by contemporaries to be an expert mathematician, astronomer, and philosopher . All but three of the books attributed by scholars to the Banū Mūsā are now lost. Many of the lost works are named in the Book of Ingenious Devices , their most famous work. The Banū Mūsā are known to have made many astronomical observations in Baghdad. Kitāb bayyana fīhī bi-ṭarīq taʿlīmī wa-madhhab handasī annahū laysa fī khārij kurat al-kawākib al-thābitah kurah tāsiʿah ("Book on
22475-406: Was close to death—that no error had been made. The brothers were saved from execution when the caliph was assassinated shortly afterwards. Of the three brothers, only the year that Mohammed died—January 873—is known. The Banū Mūsā wrote almost 20 books. Moḥammad was the most productive of the brothers; of his many works, one still exists. They worked together as well as separately: Jafar Muhammad
22630-530: Was gradually accepted as a synonym for "Persian" and still remains today as a designation for the Persian-speaking communities native to the modern Arab states of the Middle East. A series of Muslim Iranian kingdoms were later established on the fringes of the declining Abbasid Caliphate , including that of the ninth-century Samanids , under the reign of whom the Persian language was used officially for
22785-461: Was in continuous contact. The brothers are likely to have used portable instruments such as armillary spheres or dials when making their observations, which were recorded from around 847 to 869. From their Baghdad home, they observed stars in the constellation Ursa Major In 847–848, and measured the maximum and minimum altitudes of the Sun in 868–869. They also observed the September equinox in
22940-604: Was in opposition to the tradition carried by the Arab astronomer Albumasar (787–886) whose Introductorium in Astronomiam and De Magnis Coniunctionibus argued the view that both individual actions and larger scale history are determined by the stars. In the late 15th century, Giovanni Pico della Mirandola forcefully attacked astrology in Disputationes contra Astrologos , arguing that the heavens neither caused, nor heralded earthly events.
