Bematist
Bematist (), plural bematists or bematistae (), meaning 'step measurer' (from βῆμα ''bema'', meaning 'step, pace'), were specialists in ancient Greece and ancient Egypt who measured distances by pacing. Measurements of Alexander's bematists Bematists accompanied Alexander the Great on his campaign in Asia. Their measurements of the distances traveled by Alexander's army show a high degree of accuracy to the point that it had been suggested that they must have used an odometer, although there is no direct mentioning of such a device: The table below lists distances of the routes as measured by two of Alexander's bematists, Diognetus and Baeton. They were recorded in Pliny's Naturalis Historia (''NH'' 6.61–62). Another similar set of measurements is given by Strabo (11.8.9) following Eratosthenes. Eratosthenes calculated the circumference of the Earth based on work of Egyptian bematists. Notes: 1) 1 mille passus = 2) 1 Attic stadion = 3) The route is not reco ...

Circumference Of The Earth
Earth's circumference is the distance around Earth. Measured around the equator, it is . Measured passing through the poles, the circumference is . Treating the Earth as a sphere, its circumference would be its single most important measurement. The first known scientific measurement and calculation was done by Eratosthenes, by comparing altitudes of the mid-day sun at two places a known north–south distance apart. He achieved a great degree of precision in his computation. The Earth's shape deviates from spherical by flattening, but by only about 0.3%. Measurement of Earth's circumference has been important to navigation since ancient times. In modern times, Earth's circumference has been used to define fundamental units of measurement of length: the nautical mile in the seventeenth century and the metre in the eighteenth. Earth's polar circumference is very near to 21,600 nautical miles because the nautical mile was intended to express one minute of latitude (see meridia ...

Eratosthenes
Eratosthenes of Cyrene (; ; – ) was an Ancient Greek polymath: a Greek mathematics, mathematician, geographer, poet, astronomer, and music theory, music theorist. He was a man of learning, becoming the chief librarian at the Library of Alexandria. His work is comparable to the study of geography, and he introduced some of the terminology, even coining the terms geography and geographer. He is best known for being the first person known to calculate the Earth's circumference, which he did by using the extensive survey results he could access in his role at the Library. His calculation was remarkably accurate (his error margin turned out to be less than 1%). He was the first to calculate Earth's axial tilt, which similarly proved to have remarkable accuracy. He created the Eratosthenes' Map of the World, first global projection of the world, incorporating Circle of latitude, parallels and Longitude, meridians based on the available geographic knowledge of his era.

Strabo
Strabo''Strabo'' (meaning "squinty", as in strabismus) was a term employed by the Romans for anyone whose eyes were distorted or deformed. The father of Pompey was called "Gnaeus Pompeius Strabo, Pompeius Strabo". A native of Sicily so clear-sighted that he could see things at great distance as if they were nearby was also called "Strabo". (; ''Strábōn''; 64 or 63 BC) was an ancient Greece, ancient Greek geographer who lived in Anatolia, Asia Minor during the transitional period of the Roman Republic into the Roman Empire. He is best known for his work ''Geographica'', which presented a descriptive history of people and places from different regions of the world known during his lifetime. Additionally, Strabo authored historical works, but only fragments and quotations of these survive in the writings of other authors. Early life Strabo was born to an affluent family from Amasya, Amaseia in Kingdom of Pontus, Pontus in around 64BC. His family had been involved in politics s ...

Ancient Greek Technology
Ancient Greek technology developed during the 5th century BC, continuing up to and including the Roman period, and beyond. Inventions that are credited to the ancient Greeks include the gear, screw, rotary mills, bronze casting techniques, water clock, water organ, the torsion catapult, the use of steam to operate some experimental machines and toys, and a chart to find prime numbers. Many of these inventions occurred late in the Greek period, often inspired by the need to improve weapons and tactics in war. However, peaceful uses are shown by their early development of the watermill, a device which pointed to further exploitation on a large scale under the Romans. They developed surveying and mathematics to an advanced state, and many of their technical advances were published by philosophers, like Archimedes and Heron. Water technology Some fields that were encompassed in the area of water resources (mainly for urban use) included groundwater exploitation, construction of aqued ...

Military Personnel Of Alexander The Great
A military, also known collectively as armed forces, is a heavily armed, highly organized force primarily intended for warfare. Militaries are typically authorized and maintained by a sovereign state, with their members identifiable by a distinct military uniform. They may consist of one or more military branches such as an army, navy, air force, space force, marines, or coast guard. The main task of a military is usually defined as defence of their state and its interests against external armed threats. In broad usage, the terms "armed forces" and "military" are often synonymous, although in technical usage a distinction is sometimes made in which a country's armed forces may include other paramilitary forces such as armed police. Beyond warfare, the military may be employed in additional sanctioned and non-sanctioned functions within the state, including internal security threats, crowd control, promotion of political agendas, emergency services and reconstruction, prot ...

Gromatici
''Gromatici'' (from Latin '' groma'' or ''gruma'', a surveyor's pole) or ''agrimensores'' was the name for land surveyors amongst the ancient Romans. The "gromatic writers" were technical writers who codified their techniques of surveying, most of whose preserved writings are found in the '' Corpus Agrimensorum Romanorum''. History Roman Republic At the foundation of a colony and the assignation of lands the auspices were taken, for which purpose the presence of the augur was necessary. But the business of the augur did not extend beyond the religious part of the ceremony: the division and measurement of the land were made by professional measurers. These were the ''finitores'' mentioned by the early writers, who in the later periods were called ''mensores'' and ''agrimensores''. The business of a ''finitor'' could only be done by a free man, and the honourable nature of his office is indicated by the rule that there was no bargain for his services, but he received his ...

Ancient Greek Units Of Measurement
Ancient Greek units of measurement varied according to location and epoch. Systems of ancient weights and measures evolved as needs changed; Solon and other lawgivers also reformed them ''en bloc''. Some units of measurement were found to be convenient for trade within the Mediterranean region and these units became increasingly common to different city states. The calibration and use of measuring devices became more sophisticated. By about 500 BC, Athens had a central depository of official weights and measures, the '' Tholos'', where merchants were required to test their measuring devices against official standards. Length Some Greek measures of length were named after parts of the body, such as the (''daktylos'', plural: ''daktyloi'') or finger (having the size of a thumb), and the ('' pous'', plural: ''podes'') or foot (having the size of a shoe). The values of the units varied according to location and epoch (e.g., in Aegina a ''pous'' was approximately , whereas in Athen ...

Olympia, Greece
Olympia ( ; ), officially Archaia Olympia ( ), is a small town in Elis (regional unit), Elis on the Peloponnese peninsula in Greece, famous for the nearby archaeological site of the same name. The site was a major Panhellenic sanctuary, Panhellenic religious sanctuary of ancient Greece, where the ancient Olympic Games were held every Olympiad, four years throughout classical antiquity, from the 8th century BC to the 4th century AD. They were Olympic Games, restored on a global basis in 1894 in honor of the ideal of peaceful international contention for excellence. The sacred precinct, named the Altis, was primarily dedicated to Zeus, although other gods were worshipped there. The games conducted in his name drew visitors from all over the Greek world as one of a group of such "Panhellenic" centres, which helped to build the identity of the ancient Greeks as a nation. Despite the name, it is nowhere near Mount Olympus in northern Greece, where the twelve Olympians, the major deit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Elis (city)
Elis (, , in the local dialect: Ϝᾶλις, Modern ) was the capital city of the ancient polis (city-state) of Elis, in ancient Greece. It was situated in the northwest of the Peloponnese, to the west of Arcadia. Just before the Peneius emerges from the hills into the plain, the valley of the river is contracted on the south by a projecting hill of a peaked form, and nearly in height. This hill was the acropolis of Elis, and commanded as well the narrow valley of the Peneius as the open plain beyond. The ancient city lay at the foot of the hill, and extended across the river, as Strabo says that the Peneius flowed through the city; but since no remains are now found on the right or northern bank, it is probable that all the public buildings were on the left bank of the river, more especially as Pausanias does not make any allusion to the river in his description of the city. Elis is mentioned as a town of the Epeii by Homer in the Catalogue of Ships in the ''Iliad''; but in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chersonissos
Hersonissos (, meaning “peninsula”, ''Chersónisos'', ), also transliterated as ''Chersonissos'' and ''Hersónisos'', is a town and a local government unit in the north of Crete, bordering the Mediterranean / Aegean Sea. The town is about 25 kilometers east of Heraklion and west of Agios Nikolaos. What is usually called Hersonissos is in fact its peninsula and harbour. It is part of the Heraklion regional unit.
