130-444: Bark mills , also known as Catskill's mills , are water , steam , horse , ox or wind -powered edge mills used to process the bark, roots, and branches of various tree species into a fine powder known as tanbark , used for tanning leather . This powdering allowed the tannin to be extracted more efficiently from its woody source material. A barker would strip the bark from trees so that it might be ground in such mills, and

260-450: A forge , fulling stocks in a fulling mill and so on. However, in corn mills rotation about a vertical axis was required to drive its stones. The horizontal rotation was converted into the vertical rotation by means of gearing, which also enabled the runner stones to turn faster than the waterwheel. The usual arrangement in British and American corn mills has been for the waterwheel to turn

390-534: A Carthaginian army there. This was the first time a European force had invaded the region. After this war he controlled most of south-east Sicily and had himself proclaimed king, in imitation of the Hellenistic monarchs of the east. Agathocles then invaded Italy ( c.  300 BC ) in defense of Tarentum against the Bruttians and Romans , but was unsuccessful. Greeks in pre-Roman Gaul were mostly limited to

520-406: A Hellenistic period is a 19th-century concept, and did not exist in ancient Greece . Although words related in form or meaning, e.g. Hellenist ( Ancient Greek : Ἑλληνιστής , Hellēnistēs ), have been attested since ancient times, it has been attributed to the 19th century German historian Johann Gustav Droysen , who in his classic work Geschichte des Hellenismus ( History of Hellenism ), coined

650-648: A carefully neutral posture and acting to preserve the balance of power between the major Hellenistic kingdoms. Initially, Rhodes had very close ties with the Ptolemaic kingdom. Rhodes later became a Roman ally against the Seleucids, receiving some territory in Caria for their role in the Roman–Seleucid War (192–188 BC). Rome eventually turned on Rhodes and annexed the island as a Roman province. The west Balkan coast

780-562: A combined Theban and Athenian army at the Battle of Chaeronea after a decade of desultory conflict. In the aftermath, Philip formed the League of Corinth , effectively bringing the majority of Greece under his direct sway. He was elected Hegemon of the league, and a campaign against the Achaemenid Empire of Persia was planned. However in 336 BC, while this campaign was in its early stages, he

910-470: A common Attic -based Greek dialect, known as Koine Greek , which became the lingua franca throughout the ancient world. During the Hellenistic period, Greek cultural influence reached its peak in the Mediterranean and beyond. Prosperity and progress in the arts , literature , theatre , architecture , music , mathematics , philosophy , and science characterize the era. The Hellenistic period saw

1040-437: A dam on the river above the mill and a more elaborate millpond, sluice gate, mill race and spillway or tailrace. An inherent problem in the overshot mill is that it reverses the rotation of the wheel. If a miller wishes to convert a breastshot mill to an overshot wheel all the machinery in the mill has to be rebuilt to take account of the change in rotation. An alternative solution was the pitchback or backshot wheel. A launder

1170-718: A day. By 610 or 670 AD, the watermill was introduced to Japan via Korean Peninsula . It also became known in Tibet by at least 641 AD. According to Greek historical tradition, India received water-mills from the Roman Empire in the early 4th century AD when a certain Metrodoros introduced "water-mills and baths, unknown among them [the Brahmans] till then". Engineers under the Caliphates adopted watermill technology from former provinces of

1300-600: A fleet. Ptolemy invaded Syria and defeated Antigonus' son, Demetrius Poliorcetes , in the Battle of Gaza of 312 BC which allowed Seleucus to secure control of Babylonia , and the eastern satrapies. In 310 BC, Cassander had young King Alexander IV and his mother Roxana murdered, ending the Argead dynasty which had ruled Macedon for several centuries. Antigonus then sent his son Demetrius to regain control of Greece. In 307 BC he took Athens, expelling Demetrius of Phaleron , Cassander's governor, and proclaiming

1430-452: A horizontal shaft on which is also mounted a large pit wheel . This meshes with the wallower , mounted on a vertical shaft, which turns the (larger) great spur wheel (mounted on the same shaft). This large face wheel , set with pegs, in turn, turned a smaller wheel (such as a lantern gear ) known as a stone nut, which was attached to the shaft that drove the runner stone. The number of runner stones that could be turned depended directly upon

1560-427: A horizontal water wheel on a vertical axle, and the other with a vertical wheel on a horizontal axle. The oldest of these were horizontal mills in which the force of the water, striking a simple paddle wheel set horizontally in line with the flow turned a runner stone balanced on the rynd which is atop a shaft leading directly up from the wheel. The bedstone does not turn. The problem with this type of mill arose from

1690-499: A league against Cassander's Macedon. The decisive engagement of the war came when Lysimachus invaded and overran much of western Anatolia, but was soon isolated by Antigonus and Demetrius near Ipsus in Phrygia . Seleucus arrived in time to save Lysimachus and utterly crushed Antigonus at the Battle of Ipsus in 301 BC. Seleucus' war elephants proved decisive; Antigonus was killed, and Demetrius fled back to Greece to attempt to preserve

1820-501: A liberator than a conqueror. In addition, much of the area conquered would continue to be ruled by the Diadochi , Alexander's generals and successors. Initially, the whole empire was divided among them; however, some territories were lost relatively quickly or only remained nominally under Macedonian rule. After 200 years, only much reduced and rather degenerate states remained, until the conquest of Ptolemaic Egypt by Rome. When Alexander

1950-598: A mostly rural work process, than the ancient urban-centered literary class had been. By Carolingian times, references to watermills had become "innumerable" in Frankish records. The Domesday Book , compiled in 1086, records 5,624 watermills in England alone. Later research estimates a less conservative number of 6,082 that should be considered a minimum as the northern reaches of England were never properly recorded. In 1300, this number had risen to between 10,000 and 15,000. By

2080-618: A new agreement with Antipater at the Treaty of Triparadisus . Antipater was made regent of the Empire, and the two kings were moved to Macedon. Antigonus remained in charge of Asia Minor, Ptolemy retained Egypt, Lysimachus retained Thrace and Seleucus I controlled Babylon . The second Diadochi war began following the death of Antipater in 319 BC. Passing over his own son, Cassander , Antipater had declared Polyperchon his successor as Regent . Cassander rose in revolt against Polyperchon (who

2210-457: A shaft with a horizontal axis to one with a vertical axis. Although to date only a few dozen Roman mills are archaeologically traced, the widespread use of aqueducts in the period suggests that many remain to be discovered. Recent excavations in Roman London, for example, have uncovered what appears to be a tide mill together with a possible sequence of mills worked by an aqueduct running along

2340-420: A single waterwheel driving more than one set of stones was drawn by Henry Beighton in 1723 and published in 1744 by J. T. Desaguliers . The overshot wheel was a later innovation in waterwheels and was around two and a half times more efficient than the undershot. The undershot wheel, in which the main water wheel is simply set into the flow of the mill race, suffers from an inherent inefficiency stemming from

2470-472: A source of water, used to provide additional power to watermills and water-raising machines. Fulling mills, and steel mills may have spread from Al-Andalus to Christian Spain in the 12th century. Industrial watermills were also employed in large factory complexes built in al-Andalus between the 11th and 13th centuries. The engineers of the Islamic world used several solutions to achieve the maximum output from

2600-435: A standing army of mercenaries and a small core of Greco-Macedonian settlers. Promotion of immigration from Greece was important in the establishment of this system. Hellenistic monarchs ran their kingdoms as royal estates and most of the heavy tax revenues went into the military and paramilitary forces which preserved their rule from any kind of revolution. Macedonian and Hellenistic monarchs were expected to lead their armies on

2730-526: A summary of Arrian 's Events after Alexander , by Photios I of Constantinople . Lesser supplementary sources include Curtius Rufus , Pausanias , Pliny , and the Byzantine encyclopedia the Suda . In the field of philosophy, Diogenes Laërtius ' Lives and Opinions of Eminent Philosophers is the main source; works such as Cicero 's De Natura Deorum also provide some further detail of philosophical schools in

2860-408: A vertical-waterwheel via a gear mechanism, and the other equipped with a horizontal-waterwheel without such a mechanism. The former type can be further divided, depending on where the water hits the wheel paddles, into undershot, overshot, breastshot and reverse shot waterwheel mills. The Greeks invented the two main components of watermills, the waterwheel and toothed gearing, and used, along with

2990-581: A water-powered grain-mill to have existed near the palace of king Mithradates VI Eupator at Cabira , Asia Minor , before 71 BC. The Roman engineer Vitruvius has the first technical description of a watermill, dated to 40/10 BC; the device is fitted with an undershot wheel and power is transmitted via a gearing mechanism . He also seems to indicate the existence of water-powered kneading machines. The Greek epigrammatist Antipater of Thessalonica tells of an advanced overshot wheel mill around 20 BC/10 AD. He praised for its use in grinding grain and

3120-495: A watermill. One solution was to mount them to piers of bridges to take advantage of the increased flow. Another solution was the ship mill, a type of watermill powered by water wheels mounted on the sides of ships moored in midstream . This technique was employed along the Tigris and Euphrates rivers in 10th-century Iraq , where large ship mills made of teak and iron could produce 10 tons of flour from corn every day for

3250-565: Is Athens , which had been decisively defeated by Antipater in the Lamian war (323–322 BC) and had its port in the Piraeus garrisoned by Macedonian troops who supported a conservative oligarchy . After Demetrius Poliorcetes captured Athens in 307 BC and restored the democracy , the Athenians honored him and his father Antigonus by placing gold statues of them on the agora and granting them

3380-500: Is a structure that uses a water wheel or water turbine to drive a mechanical process such as milling (grinding) , rolling , or hammering . Such processes are needed in the production of many material goods, including flour , lumber , paper , textiles , and many metal products. These watermills may comprise gristmills , sawmills , paper mills , textile mills , hammermills , trip hammering mills, rolling mills , and wire drawing mills. One major way to classify watermills

3510-653: Is by an essential trait about their location: tide mills use the movement of the tide; ship mills are water mills onboard (and constituting) a ship. Watermills impact the river dynamics of the watercourses where they are installed. During the time watermills operate channels tend to sedimentate , particularly backwater . Also in the backwater area, inundation events and sedimentation of adjacent floodplains increase. Over time however these effects are cancelled by river banks becoming higher. Where mills have been removed, river incision increases and channels deepen. There are two basic types of watermills, one powered by

3640-420: Is by wheel orientation (vertical or horizontal), one powered by a vertical waterwheel through a gear mechanism, and the other equipped with a horizontal waterwheel without such a mechanism. The former type can be further subdivided, depending on where the water hits the wheel paddles, into undershot, overshot, breastshot and pitchback (backshot or reverse shot) waterwheel mills. Another way to classify water mills

3770-775: Is carried out in the UK at Daniels Mill , Little Salkeld Mill and Redbournbury Mill . This was boosted to overcome flour shortages during the Covid pandemic. Some old mills are being upgraded with modern hydropower technology, such as those worked on by the South Somerset Hydropower Group in the UK. In some developing countries, watermills are still widely used for processing grain. For example, there are thought to be 25,000 operating in Nepal, and 200,000 in India. Many of these are still of

3900-428: Is the tide mill . This mill might be of any kind, undershot, overshot or horizontal but it does not employ a river for its power source. Instead a mole or causeway is built across the mouth of a small bay. At low tide, gates in the mole are opened allowing the bay to fill with the incoming tide. At high tide the gates are closed, trapping the water inside. At a certain point a sluice gate in the mole can be opened allowing

4030-498: Is the preeminent role of France in the introduction of new innovative uses of waterpower. However, he has drawn attention to the dearth of studies of the subject in several other countries. The waterwheel was found in China from 30 AD onwards, when it was used to power trip hammers , the bellows in smelting iron , and in one case, to mechanically rotate an armillary sphere for astronomical observation (see Zhang Heng ). Although

4160-759: The Venus de Milo . A form of Hellenistic architecture arose which especially emphasized the building of grand monuments and ornate decorations, as exemplified by structures such as the Pergamon Altar . The religious sphere of Greek religion expanded through syncretic facets to include new gods such as the Greco-Egyptian Serapis , eastern deities such as Attis and Cybele , and a syncretism between Hellenistic culture and Buddhism in Bactria and Northwest India . Scholars and historians are divided as to which event signals

4290-469: The Aurelian walls in the late 3rd century. A breastshot wheel mill dating to the late 2nd century AD was excavated at Les Martres-de-Veyre , France. The 3rd century AD Hierapolis water-powered stone sawmill is the earliest known machine to incorporate the mechanism of a crank and connecting rod . Further sawmills, also powered by crank and connecting rod mechanisms, are archaeologically attested for

The industrial uses of watermills in the Islamic world date back to the 7th century, while horizontal-wheeled and vertical-wheeled watermills were both in widespread use by

4550-526: The Diadochi wars broke out when Perdiccas planned to marry Alexander's sister Cleopatra and began to question Antigonus I Monophthalmus ' leadership in Asia Minor . Antigonus fled for Greece, and then, together with Antipater and Craterus (the satrap of Cilicia who had been in Greece fighting the Lamian war ) invaded Anatolia . The rebels were supported by Lysimachus , the satrap of Thrace and Ptolemy,

4680-633: The Greco-Bactrian kingdom ). It can be argued that some of the changes across the Macedonian Empire after Alexander's conquests and during the rule of the Diadochi would have occurred without the influence of Greek rule. As mentioned by Peter Green , numerous factors of conquest have been merged under the term Hellenistic period . Specific areas conquered by Alexander's invading army, including Egypt and areas of Asia Minor and Mesopotamia "fell" willingly to conquest and viewed Alexander as more of

4810-571: The Greek colonies in Illyria. Illyrians imported weapons and armor from the ancient Greeks (such as the Illyrian type helmet , originally a Greek type) and also adopted the ornamentation of ancient Macedon on their shields and their war belts (a single one has been found, dated 3rd century BC at modern Selcë e Poshtme , a part of Macedon at the time under Philip V of Macedon ). The Odrysian Kingdom

This resulted in an influx of Greek colonists and

5070-464: The Mediterranean coast of Provence , France . The first Greek colony in the region was Massalia , which became one of the largest trading ports of Mediterranean by the 4th century BC with 6,000 inhabitants. Massalia was also the local hegemon , controlling various coastal Greek cities like Nice and Agde . The coins minted in Massalia have been found in all parts of Liguro-Celtic Gaul. Celtic coinage

5200-552: The Ptolemaic Kingdom , which might otherwise have been lost, has been preserved in papyrological documents. This is particularly noteworthy given the limited documentation available for their Seleucid counterparts. Ancient Greece had traditionally been a fractious collection of fiercely independent city-states. After the Peloponnesian War (431–404 BC), Greece had fallen under a Spartan hegemony , in which Sparta

5330-467: The Roman Empire . So-called 'Greek Mills' used water wheels with a horizontal wheel (and vertical shaft). A "Roman Mill" features a vertical wheel (on a horizontal shaft). Greek style mills are the older and simpler of the two designs, but only operate well with high water velocities and with small diameter millstones. Roman style mills are more complicated as they require gears to transmit the power from

5460-679: The Roman Republic against the Carthaginian Empire during the Second Punic War (218–201 BC). However, Emporion lost its political independence around 195 BC with the establishment of the Roman province of Hispania Citerior and by the 1st century BC had become fully Romanized in culture. The Hellenistic states of Asia and Egypt were run by an occupying imperial elite of Greco-Macedonian administrators and governors propped up by

5590-589: The Romans , undershot, overshot and breastshot waterwheel mills. The earliest evidence of a water-driven wheel appears in the technical treatises Pneumatica and Parasceuastica of the Greek engineer Philo of Byzantium (ca. 280−220 BC). The British historian of technology M.J.T. Lewis has shown that those portions of Philo of Byzantium's mechanical treatise which describe water wheels and which have been previously regarded as later Arabic interpolations, actually date back to

5720-539: The Sui dynasty (581–618 AD) was said to operate hundreds of them by the beginning of the 6th century. A source written in 612 AD mentions Buddhist monks arguing over the revenues gained from watermills. The Tang dynasty (618–907 AD) 'Ordinances of the Department of Waterways' written in 737 AD stated that watermills should not interrupt riverine transport and in some cases were restricted to use in certain seasons of

The capacity of the mills has been estimated at 4.5 tons of flour per day, sufficient to supply enough bread for the 12,500 inhabitants occupying the town of Arelate at that time. A similar mill complex existed on the Janiculum hill, whose supply of flour for Rome 's population was judged by emperor Aurelian important enough to be included in

5980-619: The granary in Baghdad . More than 300 watermills were at work in Iran till 1960. Now only a few are still working. One of the famous ones is the water mill of Askzar and the water mill of the Yazd city, still producing flour. Typically, water is diverted from a river or impoundment or mill pond to a turbine or water wheel, along a channel or pipe (variously known as a flume , head race, mill race , leat , leet, lade (Scots) or penstock ). The force of

6110-525: The " Nesiotic League " of the Cyclades . These federations involved a central government which controlled foreign policy and military affairs, while leaving most of the local governing to the city states , a system termed sympoliteia . In states such as the Achaean league, this also involved the admission of other ethnic groups into the federation with equal rights, in this case, non- Achaeans . The Achean league

6240-537: The 6th century AD water-powered stone sawmills at Gerasa and Ephesus . Literary references to water-powered marble saws in what is now Germany can be found in Ausonius 4th century AD poem Mosella . They also seem to be indicated about the same time by the Christian saint Gregory of Nyssa from Anatolia , demonstrating a diversified use of water-power in many parts of the Roman Empire . The earliest turbine mill

6370-608: The 9th century. A variety of industrial watermills were used in the Islamic world, including gristmills , hullers , sawmills , ship mills, stamp mills , steel mills , sugar mills , and tide mills . By the 11th century, every province throughout the Islamic world had these industrial watermills in operation, from al-Andalus and North Africa to the Middle East and Central Asia . Muslim and Middle Eastern Christian engineers also used crankshafts and water turbines , gears in watermills and water-raising machines , and dams as

6500-667: The Aegean (204–200 BC) and ignored Roman demands for non-intervention in Greece by invading Attica. In 198 BC, during the Second Macedonian War Philip was decisively defeated at Cynoscephalae by the Roman proconsul Titus Quinctius Flamininus and Macedon lost all its territories in Greece proper. Southern Greece was now thoroughly brought into the Roman sphere of influence , though it retained nominal autonomy. The end of Antigonid Macedon came when Philip V's son, Perseus,

Under the Antigonids, Macedonia was often short on funds, the Pangaeum mines were no longer as productive as under Philip II, the wealth from Alexander's campaigns had been used up and the countryside pillaged by the Gallic invasion . A large number of the Macedonian population had also been resettled abroad by Alexander or had chosen to emigrate to

6760-456: The British chemist and sinologist Joseph Needham speculates that the water-powered millstone could have existed in Han China by the 1st century AD, there is no sufficient literary evidence for it until the 5th century AD. In 488 AD, the mathematician and engineer Zu Chongzhi had a watermill erected which was inspected by Emperor Wu of Southern Qi (r. 482–493 AD). The engineer Yang Su of

6890-513: The Great of the capital of the Roman Empire to Constantinople in AD 330. Though this scope of suggested dates demonstrates a range of academic opinion, a generally accepted date by most of scholarship has been that of 31/30 BC. The word originated from ancient Greek Ἑλληνιστής ( Hellēnistḗs , "one who uses the Greek language"), from Ἑλλάς ( Hellás , "Greece"); as if "Hellenist" + "ic". The idea of

7020-416: The Great died (10 June 323 BC), he left behind a sprawling empire that was composed of many essentially autonomous territories called satrapies . Without a chosen successor, there were immediate disputes among his generals as to who should be king of Macedon. These generals became known as the Diadochi ( Ancient Greek : Διάδοχοι , Diadokhoi , meaning "Successors"). Meleager and the infantry supported

7150-532: The Greek 3rd century BC original. The sakia gear is, already fully developed, for the first time attested in a 2nd-century BC Hellenistic wall painting in Ptolemaic Egypt . Lewis assigns the date of the invention of the horizontal-wheeled mill to the Greek colony of Byzantium in the first half of the 3rd century BC, and that of the vertical-wheeled mill to Ptolemaic Alexandria around 240 BC. The Greek geographer Strabo reports in his Geography

7280-691: The Greek world, making the endless conflicts between the cities that had marked the 5th and 4th centuries BC seem petty and unimportant. It led to a steady emigration, particularly of the young and ambitious, to the new Greek empires in the east. Many Greeks migrated to Alexandria , Antioch , and the many other new Hellenistic cities founded in Alexander's wake, as far away as modern Afghanistan and Pakistan . Independent city states were unable to compete with Hellenistic kingdoms and were usually forced to ally themselves to one of them for defense, giving honors to Hellenistic rulers in return for protection. One example

7410-620: The Greeks during the 8th century BC. In 4th-century BC Sicily the leading Greek city and hegemon was Syracuse . During the Hellenistic period the leading figure in Sicily was Agathocles of Syracuse (361–289 BC) who seized the city with an army of mercenaries in 317 BC. Agathocles extended his power throughout most of the Greek cities in Sicily, fought a long war with the Carthaginians , at one point invading Tunisia in 310 BC and defeating

7540-577: The Hellenistic period breaks off after the battle of Ipsus (301 BC). Another important source, Plutarch 's ( c.  AD 50  – c.  120 ) Parallel Lives although more preoccupied with issues of personal character and morality, outlines the history of important Hellenistic figures. Appian of Alexandria (late 1st century AD–before 165) wrote a history of the Roman empire that includes information of some Hellenistic kingdoms. Other sources include Justin 's (2nd century AD) epitome of Pompeius Trogus ' Historiae Philipicae and

7670-488: The Hellenistic period is Polybius of Megalopolis (c. 200–118), a statesman of the Achaean League until 168 BC when he was forced to go to Rome as a hostage. His Histories eventually grew to a length of forty books, covering the years 220 to 167 BC. The most important source after Polybius is Diodorus Siculus who wrote his Bibliotheca historica between 60 and 30 BC and reproduced some important earlier sources such as Hieronymus, but his account of

7800-486: The Hellenistic period. Inscriptions on stone or metal were commonly erected throughout the Greek world for public display, a practice which originated well before the time of Alexander the Great, but saw substantial expansion during the Hellenistic Period. The majority of these inscriptions are located on the Greek mainland , the Greek islands , and western Asia Minor . While they become increasingly rare towards

8060-464: The Macedonians themselves were looked down upon as semi-barbaric by the rest of the Greeks. However, Macedon controlled a large area and had a relatively strong centralized government, in comparison to most Greek states. Philip II was a strong and expansionist king who took every opportunity to expand Macedonian territory. In 352 BC he annexed Thessaly and Magnesia . In 338 BC, Philip defeated

8190-460: The ancient Egyptian bureaucracy, highly centralized and focused on squeezing as much revenue out of the population as possible through tariffs, excise duties, fines, taxes, and so forth. A whole class of petty officials, tax farmers, clerks, and overseers made this possible. The Egyptian countryside was directly administered by this royal bureaucracy. External possessions such as Cyprus and Cyrene were run by strategoi , military commanders appointed by

8320-416: The buckets fill, the weight of the water starts to turn the wheel. The water spills out of the bucket on the down side into a spillway leading back to river. Since the wheel itself is set above the spillway, the water never impedes the speed of the wheel. The impulse of the water on the wheel is also harnessed in addition to the weight of the water once in the buckets. Overshot wheels require the construction of

8450-485: The candidacy of Alexander's half-brother, Philip Arrhidaeus , while Perdiccas , the leading cavalry commander, supported waiting until the birth of Alexander's child by Roxana . After the infantry stormed the palace of Babylon , a compromise was arranged – Arrhidaeus (as Philip III) should become king and should rule jointly with Roxana's child, assuming that it was a boy (as it was, becoming Alexander IV ). Perdiccas himself would become regent ( epimeletes ) of

8580-442: The city free again. Demetrius now turned his attention to Ptolemy, defeating his fleet at the Battle of Salamis and taking control of Cyprus. In the aftermath of this victory, Antigonus took the title of king ( basileus ) and bestowed it on his son Demetrius Poliorcetes , the rest of the Diadochi soon followed suit. Demetrius continued his campaigns by laying siege to Rhodes and conquering most of Greece in 302 BC, creating

8710-541: The country, especially in the region of the Faiyum . Alexandria , a major center of Greek culture and trade, became his capital city. As Egypt's first port city, it became the main grain exporter in the Mediterranean. The Egyptians begrudgingly accepted the Ptolemies as the successors to the pharaohs of independent Egypt, though the kingdom went through several native revolts. Ptolemy I began to order monetary contributions from

Ptolemy himself was eager to patronise the library, scientific research and individual scholars who lived on the grounds of the library. He and his successors also fought a series of wars with the Seleucids, known as

A twin flume horizontal-wheeled tide mill dating to c. 630 was excavated on Little Island . Alongside it, another tide mill was found which was powered by a vertical undershot wheel. The Nendrum Monastery mill from 787

9100-413: The death of Pyrrhus, Epirus remained a minor power. In 233 BC the Aeacid royal family was deposed and a federal state was set up called the Epirote League . The league was conquered by Rome in the Third Macedonian War (171–168 BC). Antigonus II , a student of Zeno of Citium , spent most of his rule defending Macedon against Epirus and cementing Macedonian power in Greece, first against

9230-435: The draining water to drive a mill wheel or wheels. This is particularly effective in places where the tidal differential is very great, such as the Bay of Fundy in Canada where the tides can rise fifty feet, or the now derelict village of Tide Mills, East Sussex . The last two examples in the United Kingdom which are restored to working conditions can be visited at Eling , Hampshire and at Woodbridge , Suffolk . Run of

9360-459: The dried bark was often stored in bark houses. Various machinery was used to chop, grind, riddle and pound the bark. These included Farcot ’s bark-cutting machine (used extensively in France), Weldon’s bark-grinding mill, and a device known as a Wiltze's mill or Catskill's mill (prevalent in 19th-century America). Watermill A watermill or water mill is a mill that uses hydropower . It

9490-453: The early 7th century, watermills were also well established in Ireland . A century later they began to spread across the former Roman Rhine and Danube frontier into the other parts of Germany . Ship mills and tide mills , both of which yet unattested for the ancient period, were introduced in the 6th century. In recent years, a number of new archaeological finds has consecutively pushed back

9620-487: The earth, we taste again the golden age . The Roman encyclopedist Pliny mentions in his Naturalis Historia of around 70 AD water-powered trip hammers operating in the greater part of Italy. There is evidence of a fulling mill in 73/74 AD in Antioch , Roman Syria . The 2nd century AD multiple mill complex of Barbegal in southern France has been described as "the greatest known concentration of mechanical power in

9750-488: The eastern regions, they are not entirely absent there, and they are most notably featured in public buildings and sanctuaries . The content of these inscriptions is diverse, encompassing royal correspondence addressed to cities or individuals, municipal and legal edicts, decrees commemorating rulers, officials, and individuals for their contributions, as well as laws, treaties, religious rulings, and dedications. Despite challenges in their interpretation, inscriptions are often

9880-417: The empire, and Meleager his lieutenant. Soon, however, Perdiccas had Meleager and the other infantry leaders murdered and assumed full control. The generals who had supported Perdiccas were rewarded in the partition of Babylon by becoming satraps of the various parts of the empire, but Perdiccas' position was shaky because, as Arrian writes, "everyone was suspicious of him, and he of them". The first of

10010-463: The end of the Hellenistic era. There is a wide chronological range of proposed dates that have included the final conquest of the Greek heartlands by the expansionist Roman Republic in 146 BC following the Achaean War , the final defeat of the Ptolemaic Kingdom at the Battle of Actium in 31 BC, the end of the reign of the Roman emperor Hadrian in AD 138, and the move by the emperor Constantine

10140-524: The export of Greek culture and language to these new realms, a breadth spanning as far as modern-day India. These new Greek kingdoms were also influenced by regional indigenous cultures, adopting local practices where deemed beneficial, necessary, or convenient. Hellenistic culture thus represents a fusion of the ancient Greek world with that of the Western Asian, Northeastern African, and Southwestern Asian worlds. The consequence of this mixture gave rise to

10270-421: The fact that the wheel itself, entering the water behind the main thrust of the flow driving the wheel, followed by the lift of the wheel out of the water ahead of the main thrust, actually impedes its own operation. The overshot wheel solves this problem by bringing the water flow to the top of the wheel. The water fills buckets built into the wheel, rather than the simple paddle wheel design of undershot wheels. As

10400-416: The field, along with a group of privileged aristocratic companions or friends ( hetairoi , philoi ) which dined and drank with the king and acted as his advisory council. The monarch was also expected to serve as a charitable patron of the people; this public philanthropy could mean building projects and handing out gifts but also promotion of Greek culture and religion. Ptolemy , a somatophylax , one of

10530-459: The growing power and ambition of Antigonus. He began removing and appointing satraps as if he were king and also raided the royal treasuries in Ecbatana , Persepolis and Susa , making off with 25,000 talents . Seleucus was forced to flee to Egypt and Antigonus was soon at war with Ptolemy, Lysimachus, and Cassander. He then invaded Phoenicia , laid siege to Tyre , stormed Gaza and began building

10660-400: The huge territories Alexander had conquered became subject to a strong Greek influence ( Hellenization ) for the next two or three centuries, until the rise of Rome in the west, and of Parthia in the east. As the Greek and Levantine cultures mingled, the development of a hybrid Hellenistic culture began, and persisted even when isolated from the main centres of Greek culture (for instance, in

10790-518: The lack of gearing; the speed of the water directly set the maximum speed of the runner stone which, in turn, set the rate of milling. Most watermills in Britain and the United States of America had a vertical waterwheel, one of four kinds: undershot, breast-shot, overshot and pitchback wheels. This vertical produced rotary motion around a horizontal axis, which could be used (with cams) to lift hammers in

10920-643: The language of administration and of the nobility. The nobility also adopted Greek fashions in dress , ornament, and military equipment, spreading it to the other tribes. Thracian kings were among the first to be Hellenized . After 278 BC the Odrysians had a strong competitor in the Celtic Kingdom of Tylis ruled by the kings Comontorius and Cavarus , but in 212 BC they conquered their enemies and destroyed their capital. Southern Italy ( Magna Graecia ) and south-eastern Sicily had been colonized by

11050-593: The latest war between Macedon and the Greek leagues ( the Social War of 220–217 BC) to an end, and at this time he controlled all of Greece except Athens, Rhodes and Pergamum. In 215 BC Philip, with his eye on Illyria , formed an alliance with Rome's enemy Hannibal of Carthage , which led to Roman alliances with the Achaean League , Rhodes and Pergamum. The First Macedonian War broke out in 212 BC, and ended inconclusively in 205 BC. Philip continued to wage war against Pergamum and Rhodes for control of

11180-554: The native population did not always mix; the Greeks moved and brought their own culture, but interaction did not always occur. While a few fragments exist, there are no complete surviving historical works that date to the hundred years following Alexander's death. The works of the major Hellenistic historians Hieronymus of Cardia (who worked under Alexander, Antigonus I and other successors), Duris of Samos and Phylarchus , which were used by surviving sources , are all lost. The earliest and most credible surviving source for

11310-430: The new eastern Greek cities. Up to two-thirds of the population emigrated, and the Macedonian army could only count on a levy of 25,000 men, a significantly smaller force than under Philip II. Antigonus II ruled until his death in 239 BC. His son Demetrius II soon died in 229 BC, leaving a child (Philip V) as king, with the general Antigonus Doson as regent. Doson led Macedon to victory in

11440-406: The only source available for understanding numerous events in Greek history. Papyrus served as the predominant medium for handwritten documents across the Hellenistic world, though its production was confined to Egypt . Due to Egypt's arid climate , papyrus manuscripts was almost exclusively preserved there as well. That being said, the different historical periods are not represented equally in

11570-569: The papyrological documents. Texts from the reign of Ptolemy I are notably scarce, while those from the reign of Ptolemy II are more frequently encountered, this is owing in part to the large quantities of papyri which were stuffed into human and animal mummies during his rule. Papyri have been classified into public and private documents, including literary texts, laws and regulations, official correspondence, petitions , records, and archives or collections of documents belonging to individuals of position and authority. Significant information about

11700-483: The people and, as a result, rewarded cities with high contributions with royal benefaction. This often resulted in the formation of a royal cult within the city. Reservations about this activity slowly dissipated as this worship of mortals was justified by the precedent of the worshipping of Greek heroes. The Ptolemies took on the traditions of the Egyptian Pharaohs , such as marrying their siblings ( Ptolemy II

11830-614: The power available for British grain milling. By the early 20th century, availability of cheap electrical energy made the watermill obsolete in developed countries although some smaller rural mills continued to operate commercially later throughout the century. A few historic mills such as the Water Mill , Newlin Mill and Yates Mill in the US and The Darley Mill Centre in the UK still operate for demonstration purposes. Small-scale commercial production

11960-604: The power from a toothed annular ring that is mounted near the outer edge of the wheel. This drives the machinery using a spur gear mounted on a shaft rather than taking power from the central axle . However, the basic mode of operation remains the same; gravity drives machinery through the motion of flowing water . Toward the end of the 19th century, the invention of the Pelton wheel encouraged some mill owners to replace over- and undershot wheels with Pelton wheel turbines driven through penstocks . A different type of watermill

12090-460: The reduction of human labour: Hold back your hand from the mill, you grinding girls; even if the cockcrow heralds the dawn, sleep on. For Demeter has imposed the labours of your hands on the nymphs , who leaping down upon the topmost part of the wheel, rotate its axle; with encircling cogs, it turns the hollow weight of the Nisyrian millstones . If we learn to feast toil-free on the fruits of

12220-428: The remnants of his rule, thereby recapturing a rebellious Athens. Meanwhile, Lysimachus took over Ionia , Seleucus took Cilicia , and Ptolemy captured Cyprus . After Cassander's death in c.  298 BC , however, Demetrius, who still maintained a sizable loyal army and fleet, invaded Macedon, seized the Macedonian throne (294 BC) and conquered Thessaly and most of central Greece (293–291 BC). He

12350-511: The rise of New Comedy , Alexandrian poetry , translation efforts such as the Septuagint , and the philosophies of Stoicism , Epicureanism , and Pyrrhonism . In science, the works of the mathematician Euclid and the polymath Archimedes are exemplary. Sculpture during this period was characterized by intense emotion and dynamic movement, as seen in sculptural works like the Dying Gaul and

12480-448: The river schemes do not divert water at all and usually involve undershot wheels the mills are mostly on the banks of sizeable rivers or fast flowing streams. Other watermills were set beneath large bridges where the flow of water between the stanchions was faster. At one point London bridge had so many water wheels beneath it that bargemen complained that passage through the bridge was impaired. In 1870 watermills still produced 2/3 of

12610-478: The satrap of Egypt. Although Eumenes , satrap of Cappadocia , defeated the rebels in Asia Minor, Perdiccas himself was murdered by his own generals Peithon , Seleucus , and Antigenes (possibly with Ptolemy's aid) during his invasion of Egypt ( c.  21 May to 19 June, 320 BC). Ptolemy came to terms with Perdiccas's murderers, making Peithon and Arrhidaeus regents in his place, but soon these came to

12740-420: The seven bodyguards who served as Alexander the Great 's generals and deputies, was appointed satrap of Egypt after Alexander's death in 323 BC. In 305 BC, he declared himself King Ptolemy I, later known as "Soter" (saviour) for his role in helping the Rhodians during the siege of Rhodes . Ptolemy built new cities such as Ptolemais Hermiou in upper Egypt and settled his veterans throughout

12870-621: The side of the River Fleet . In 537 AD, ship mills were ingeniously used by the East Roman general Belisarius , when the besieging Goths cut off the water supply for those mills. These floating mills had a wheel that was attached to a boat moored in a fast flowing river. The surviving evidence for watermills sharply increases with the emergence of documentary genres such as monastic charters , Christian hagiography and Germanic legal codes . These were more inclined to address watermilling,

13000-407: The spread of Greek culture was not the generalized phenomenon that the term implies. Some areas of the conquered world were more affected by Greek influences than others. The term Hellenistic also implies that the Greek populations were of majority in the areas in which they settled, but in many cases, the Greek settlers were actually the minority among the native populations. The Greek population and

13130-406: The supply of water available. As waterwheel technology improved mills became more efficient, and by the 19th century, it was common for the great spur wheel to drive several stone nuts, so that a single water wheel could drive as many as four stones. Each step in the process increased the gear ratio which increased the maximum speed of the runner stone. Adjusting the sluice gate and thus the flow of

13260-492: The term Hellenistic to refer to and define the period when Greek culture spread in the non-Greek world after Alexander's conquest. Following Droysen, Hellenistic and related terms, e.g. Hellenism , have been widely used in various contexts; a notable such use is in Culture and Anarchy by Matthew Arnold , where Hellenism is used in contrast with Hebraism . The major issue with the term Hellenistic lies in its convenience, as

13390-431: The title of king. Athens later allied itself to Ptolemaic Egypt to throw off Macedonian rule, eventually setting up a religious cult for the Ptolemaic kings and naming one of the city's phyles in honour of Ptolemy for his aid against Macedon. In spite of the Ptolemaic monies and fleets backing their endeavors, Athens and Sparta were defeated by Antigonus II during the Chremonidean War (267–261 BC). Athens

13520-583: The traditional style, but some have been upgraded by replacing wooden parts with better-designed metal ones to improve the efficiency. For example, the Centre for Rural Technology in Nepal upgraded 2,400 mills between 2003 and 2007. This is also the period when water-mills started to spread outside the former Empire. According to Cedrenus (Historiarum compendium), a certain Metrodoros who went to India in c. AD 325 "constructed water-mills and baths, unknown among them [the Brahmans] till then". Hellenistic After

13650-587: The tripartite territorial division of the Hellenistic age was in place, with the main Hellenistic powers being Macedon under Demetrius's son Antigonus II Gonatas , the Ptolemaic kingdom under Ptolemy 's son Ptolemy II and the Seleucid empire under Seleucus' son Antiochus I Soter . Epirus was a northwestern Greek kingdom in the western Balkans ruled by the Molossian Aeacidae dynasty. Epirus

13780-536: The war against the Spartan king Cleomenes III , and occupied Sparta . Philip V , who came to power when Doson died in 221 BC, was the last Macedonian ruler with both the talent and the opportunity to unite Greece and preserve its independence against the "cloud rising in the west": the ever-increasing power of Rome. He was known as "the darling of Hellas". Under his auspices the Peace of Naupactus (217 BC) brought

13910-486: The water past the main wheel allowed the miller to compensate for seasonal variations in the water supply. Finer speed adjustment was made during the milling process by tentering , that is, adjusting the gap between the stones according to the water flow, the type of grain being milled, and the grade of flour required. In many mills (including the earliest) the great spur wheel turned only one stone, but there might be several mills under one roof. The earliest illustration of

14040-596: The water's movement drives the blades of a wheel or turbine, which in turn rotates an axle that drives the mill's other machinery. Water leaving the wheel or turbine is drained through a tail race, but this channel may also be the head race of yet another wheel, turbine or mill. The passage of water is controlled by sluice gates that allow maintenance and some measure of flood control; large mill complexes may have dozens of sluices controlling complicated interconnected races that feed multiple buildings and industrial processes. Watermills can be divided into two kinds, one with

14170-456: The year. From other Tang-era sources of the 8th century, it is known that these ordinances were taken very seriously, as the government demolished many watermills owned by great families, merchants, and Buddhist abbeys that failed to acknowledge ordinances or meet government regulations. A eunuch serving Emperor Xuanzong of Tang (r. 712–756 AD) owned a watermill by 748 AD which employed five waterwheels that ground 300 bushels of wheat

14300-548: Was a union of Thracian tribes under the kings of the powerful Odrysian tribe. Various parts of Thrace were under Macedonian rule under Philip II of Macedon , Alexander the Great , Lysimachus , Ptolemy II , and Philip V but were also often ruled by their own kings. The Thracians and Agrianes were widely used by Alexander as peltasts and light cavalry , forming about one-fifth of his army. The Diadochi also used Thracian mercenaries in their armies and they were also used as colonists. The Odrysians used Greek as

14430-457: Was able to drive out the Macedonians from the Peloponnese and free Corinth, which duly joined the league. One of the few city states who managed to maintain full independence from the control of any Hellenistic kingdom was Rhodes . With a skilled navy to protect its trade fleets from pirates and an ideal strategic position covering the routes from the east into the Aegean, Rhodes prospered during

14560-483: Was also a center of education, where Celts went to learn Greek. A staunch ally of Rome, Massalia retained its independence until it sided with Pompey in 49 BC and was then taken by Caesar's forces . The city of Emporion (modern Empúries ), originally founded by Archaic-period settlers from Phocaea and Massalia in the 6th century BC near the village of Sant Martí d'Empúries (located on an offshore island that forms part of L'Escala , Catalonia , Spain ),

14690-474: Was an ally of Macedon during the reigns of Philip II and Alexander. In 281 Pyrrhus (nicknamed "the eagle", aetos ) invaded southern Italy to aid the city state of Tarentum . Pyrrhus defeated the Romans in the Battle of Heraclea and at the Battle of Asculum . Though victorious, he was forced to retreat due to heavy losses, hence the term " Pyrrhic victory ". Pyrrhus then turned south and invaded Sicily but

14820-528: Was assassinated by Ptolemy Ceraunus ("the thunderbolt"), who had taken refuge at the Seleucid court and then had himself acclaimed as king of Macedon. Ptolemy was killed when Macedon was invaded by Gauls in 279 BC —his head stuck on a spear—and the country fell into anarchy. Antigonus II Gonatas invaded Thrace in the summer of 277 and defeated a large force of 18,000 Gauls. He was quickly hailed as king of Macedon and went on to rule for 35 years. At this point

14950-628: Was assassinated. Succeeding his father, Alexander took over the Persian war himself. During a decade of campaigning, Alexander conquered the whole Persian Empire , overthrew the Persian king Darius III . The conquered lands included Asia Minor , Assyria , the Levant , Egypt , Mesopotamia , Media , Persia , and parts of modern-day Afghanistan , Pakistan , and the steppes of central Asia. The years of constant campaigning had taken their toll, however, and Alexander died in 323 BC. After his death,

15080-507: Was crushed at the Battle of Sellasia (222 BC) by the Achaean league and Macedon, who restored the power of the ephors . Other city states formed federated states in self-defense, such as the Aetolian League ( est. 370 BC), the Achaean League ( est. 280 BC), the Boeotian league , the "Northern League" ( Byzantium , Chalcedon , Heraclea Pontica and Tium ) and

15210-524: Was defeated and captured by the Romans in the Third Macedonian War (171–168 BC). During the Hellenistic period, the importance of Greece proper within the Greek-speaking world declined sharply. The great centers of Hellenistic culture were Alexandria and Antioch , capitals of Ptolemaic Egypt and Seleucid Syria respectively. The conquests of Alexander greatly widened the horizons of

15340-617: Was defeated in 288 BC when Lysimachus of Thrace and Pyrrhus of Epirus invaded Macedon on two fronts, and quickly carved up the kingdom for themselves. Demetrius fled to central Greece with his mercenaries and began to build support there and in the northern Peloponnese. He once again laid siege to Athens after they turned on him, but then struck a treaty with the Athenians and Ptolemy, which allowed him to cross over to Asia Minor and wage war on Lysimachus' holdings in Ionia , leaving his son Antigonus Gonatas in Greece. After initial successes, he

15470-449: Was forced to surrender to Seleucus in 285 BC and later died in captivity. Lysimachus, who had seized Macedon and Thessaly for himself, was forced into war when Seleucus invaded his territories in Asia Minor and was defeated and killed in 281 BC at the Battle of Corupedium , near Sardis . Seleucus then attempted to conquer Lysimachus' European territories in Thrace and Macedon, but he

15600-552: Was found in Chemtou and Testour , Roman North Africa , dating to the late 3rd or early 4th century AD. A possible water-powered furnace has been identified at Marseille , France. Mills were commonly used for grinding grain into flour (attested by Pliny the Elder ), but industrial uses as fulling and sawing marble were also applied. The Romans used both fixed and floating water wheels and introduced water power to other provinces of

15730-520: Was influenced by Greek designs, and Greek letters can be found on various Celtic coins, especially those of Southern France . Traders from Massalia ventured inland deep into France on the Rivers Durance and Rhône , and established overland trade routes deep into Gaul , and to Switzerland and Burgundy . The Hellenistic period saw the Greek alphabet spread into southern Gaul from Massalia (3rd and 2nd centuries BC) and according to Strabo , Massalia

15860-719: Was inhabited by various Illyrian tribes and kingdoms such as the kingdom of the Dalmatae and of the Ardiaei , who often engaged in piracy under Queen Teuta (reigned 231–227 BC). Further inland was the Illyrian Paeonian Kingdom and the tribe of the Agrianes . Illyrians on the coast of the Adriatic were under the effects and influence of Hellenisation and some tribes adopted Greek, becoming bilingual due to their proximity to

15990-426: Was joined by Eumenes) and was supported by Antigonus, Lysimachus and Ptolemy. In 317 BC, Cassander invaded Macedonia, attaining control of Macedon, sentencing Olympias to death and capturing the boy king Alexander IV , and his mother. In Asia, Eumenes was betrayed by his own men after years of campaign and was given up to Antigonus who had him executed. The third war of the Diadochi broke out because of

16120-436: Was placed at the end of the flume on the headrace, this turned the direction of the water without much loss of energy, and the direction of rotation was maintained. Daniels Mill near Bewdley , Worcestershire is an example of a flour mill that originally used a breastshot wheel, but was converted to use a pitchback wheel. Today it operates as a breastshot mill. Larger water wheels (usually overshot steel wheels) transmit

16250-468: Was pre-eminent but not all-powerful. Spartan hegemony was succeeded by a Theban hegemony after the Battle of Leuctra (371 BC), but after the Battle of Mantinea (362 BC) , all of Greece was so weakened that no one state could claim pre-eminence. It was against this backdrop that the ascendancy of Macedon began, under king Philip II . Macedon was located at the periphery of the Greek world, and although its royal family claimed Greek descent,

16380-511: Was reestablished in the 5th century BC with a new city ( neapolis ) on the Iberian mainland . Emporion contained a mixed population of Greek colonists and Iberian natives, and although Livy and Strabo assert that they lived in different quarters , these two groups were eventually integrated. The city became a dominant trading hub and center of Hellenistic civilization in Iberia, eventually siding with

16510-614: Was situated on an island in Strangford Lough in Northern Ireland . Its millstones are 830 mm in diameter and the horizontal wheel is estimated to have developed 7 ⁄ 8 horsepower (650 W) at its peak. Remains of an earlier mill dated at 619 were also found at the site. In a 2005 survey the scholar Adam Lucas identified the following first appearances of various industrial mill types in Western Europe. Noticeable

16640-508: Was the first to adopt this custom), having themselves portrayed on public monuments in Egyptian style and dress, and participating in Egyptian religious life. The Ptolemaic ruler cult portrayed the Ptolemies as gods, and temples to the Ptolemies were erected throughout the kingdom. Ptolemy I even created a new god, Serapis , who was a combination of two Egyptian gods: Apis and Osiris, with attributes of Greek gods . Ptolemaic administration was, like

16770-544: Was then occupied by Macedonian troops, and run by Macedonian officials. Sparta remained independent, but it was no longer the leading military power in the Peloponnese . The Spartan king Cleomenes III (235–222 BC) staged a military coup against the conservative ephors and pushed through radical social and land reforms in order to increase the size of the shrinking Spartan citizenry able to provide military service and restore Spartan power. Sparta's bid for supremacy

16900-404: Was unsuccessful and returned to Italy. After the Battle of Beneventum (275 BC) Pyrrhus lost all his Italian holdings and left for Epirus. Pyrrhus then went to war with Macedonia in 275 BC, deposing Antigonus II Gonatas and briefly ruling over Macedonia and Thessaly until 272. Afterwards, he invaded southern Greece and was killed in battle against Argos in 272 BC. After
