Eupalinos Vertical
Eupalinos () or Eupalinus of Megara was an ancient Greek engineer who built the Tunnel of Eupalinos on Samos Island in the late 6th century BC. Though the construction of the tunnel has been attributed to the tyrant Polycrates of Samos, it is now considered to be a later construction and having been built between 550 and 530 BC. In any case, the tunnel was, and is, regarded as a major feat of engineering. The tunnel long conveyed water from a spring near Mount Kastro through the mountain into the ancient city of Samos (modern Pythagoreio). It was the longest one of its time and it still exists. The tunnel was excavated from both ends, but it is not the first one known to be built in this manner -- a tunnel channeling water to Jerusalem was built from both ends at the same time earlier, in the 8th century BC. The route of the tunnel does not follow a direct line -- for several hundred meters on both ends, it does follow a straight line, but in the middle third, there are sever ...

Tunnel Of Eupalinos
The Tunnel of Eupalinos or Eupalinian aqueduct () is a tunnel of length running through Mount Kastro in Samos Island, Samos, Greece, built in the 6th century BC to serve as an Aqueduct (water supply), aqueduct. The tunnel is the second known tunnel in history which was excavated from both ends (, "having two openings"), and the first with a geometry-based approach in doing so. Today it is a popular tourist attraction. The tunnel is inscribed on the UNESCO World Heritage List along with the nearby Pythagoreion and Heraion of Samos, and it was designated as an List of Historic Civil Engineering Landmarks, International Historic Civil Engineering Landmark in 2017. Early history The Eupalinian aqueduct is described by Herodotus (''Histories'' 3.60): :I have dwelt longer upon the history of the Samians than I should otherwise have done, because they are responsible for three of the greatest building and engineering feats in the Greek world: the first is a tunnel nearly a mile long, ...

Geraneia
Geraneia Mountains or Yerania Ori () are a mountain range in Corinthia and West Attica, Greece. Its highest point is the peak ''Makryplagi'' (), elevation 1,351 m. It covers the northern part of the isthmus between the Gulf of Corinth and the Saronic Gulf. It spans 5–10 km from north to south and 30 km from east to west. The geography of Geraneia includes forests in the south, the west and the northern part at an elevation of under 900 to 1,000 m. Barren land is in the central part. The grasslands and some bushes lies to the northwest. Farmlands and some barren land lies to the south. The name of the mountain dates back to ancient times. During the Peloponnesian War, the Corinthians and their allies occupied the heights of Geraneia and marched to Megara with a large force. The wolf The wolf (''Canis lupus''; : wolves), also known as the grey wolf or gray wolf, is a Canis, canine native to Eurasia and North America. More than thirty subspecies of Canis lu ...

Ancient Megarians
Ancient history is a time period from the beginning of writing and recorded human history through late antiquity. The span of recorded history is roughly 5,000 years, beginning with the development of Sumerian cuneiform script. Ancient history covers all continents inhabited by humans in the period 3000 BCAD 500, ending with the expansion of Islam in late antiquity. The three-age system periodises ancient history into the Stone Age, the Bronze Age, and the Iron Age, with recorded history generally considered to begin with the Bronze Age. The start and end of the three ages vary between world regions. In many regions the Bronze Age is generally considered to begin a few centuries prior to 3000 BC, while the end of the Iron Age varies from the early first millennium BC in some regions to the late first millennium AD in others. During the time period of ancient history, the world population was exponentially increasing due to the Neolithic Revolution, which was in full prog ...

6th-century BC Greek People
The 6th century is the period from 501 through 600 in line with the Julian calendar. In the West, the century marks the end of Classical Antiquity and the beginning of the Middle Ages. The collapse of the Western Roman Empire late in the previous century left Europe fractured into many small Germanic kingdoms competing fiercely for land and wealth. From the upheaval the Franks rose to prominence and carved out a sizeable domain covering much of modern France and Germany. Meanwhile, the surviving Eastern Roman Empire began to expand under Emperor Justinian, who recaptured North Africa from the Vandals and attempted fully to recover Italy as well, in the hope of reinstating Roman control over the lands once ruled by the Western Roman Empire. Owing in part to the collapse of the Roman Empire along with its literature and civilization, the sixth century is generally considered to be the least known about in the Dark Ages. In its second golden age, the Sassanid Empire reached the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Corinthia
Corinthia (; ) is one of the regional units of Greece. It is part of the modern regions of Greece, region of Peloponnese (region), Peloponnese. It is situated around the city of Corinth, in the north-eastern part of the Peloponnese peninsula. Geography Corinthia borders on Achaea to the west and southwest, the Gulf of Corinth and Attica to the north, the Saronic Gulf to the east, Argolis to the south and Arcadia (regional unit), Arcadia to the southwest. The Corinth Canal, carrying ship traffic between the Ionian Sea, Ionian and the Aegean Sea, Aegean seas, is about east of Corinth, cutting through the Isthmus of Corinth. Corinthia is increasingly seen as part of the wider metropolitan area of Athens, with municipalities, such as Agioi Theodoroi in the easternmost part of the regional unit, being considered suburbs of Athens. The area around Corinth and the western Saronic Gulf, Saronic including the southeastern part are made up of fault lines including the Corinth Fault, the P ...

Hydraulic Engineering
Hydraulic engineering as a sub-discipline of civil engineering is concerned with the flow and conveyance of fluids, principally water and sewage. One feature of these systems is the extensive use of gravity as the motive force to cause the movement of the fluids. This area of civil engineering is intimately related to the design of bridges, dams, channels, canals, and levees, and to both sanitary and environmental engineering. Hydraulic engineering is the application of the principles of fluid mechanics to problems dealing with the collection, storage, control, transport, regulation, measurement, and use of water.Prasuhn, Alan L. ''Fundamentals of Hydraulic Engineering''. Holt, Rinehart, and Winston: New York, 1987. Before beginning a hydraulic engineering project, one must figure out how much water is involved. The hydraulic engineer is concerned with the transport of sediment by the river, the interaction of the water with its alluvial boundary, and the occurrence of scour a ...

Pythagoreio
Pythagoreio () is a town and municipal unit on the island of Samos, North Aegean, Greece. Before the 2011 local government reform, Pythagoreio was a municipality.

The archaeological remains in the town, known collectively as Pythagoreion, has designated a joint UNESCO World Heritage Site with nearby Heraion. The seat of the municipality was the town of Pythagorio, formerly known as Tigani. The town was renamed in 1955 to honour the locally born mathematician and philosopher Pythagoras. The port of the town is considered to be the oldest man-made port of the Mediterranean Sea. History Pythagorio is built on the ancient city of Samos.
