Eupalinos Horizontal
Eupalinos ( grc, Εὐπαλῖνος) or Eupalinus of Megara was an ancient Greek engineer who built the Tunnel of Eupalinos on Samos Island in the 6th century BC. The tunnel, presumably completed between 550 and 530 BC, is the second known tunnel in history which was excavated from both ends and the first with a methodical approach in doing so. Being also the longest tunnel of its time, the Tunnel of Eupalinos is regarded as a major feat of ancient engineering. It was constructed for the tyrant Polycrates of Samos, and was a remarkable long. It brought water to the city, passing through limestone at the base of a hill; this tunnel still exists. The Greek historian Herodotus describes the tunnel briefly in his '' Histories'' (3.60) and calls Eupalinos of Megara its architect: Eupalinos is considered the first hydraulic engineer in history whose name has been passed down. Apart from that, though, nothing more is known about him.Tom Apostol, p.33 A large road tunnel, named aft ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tunnel Of Eupalinos
The Tunnel of Eupalinos or Eupalinian aqueduct ( el, Ευπαλίνιον όρυγμα, translit=Efpalinion orygma) is a tunnel of length running through Mount Kastro in Samos, Greece, built in the 6th century BC to serve as an 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 International Historic Civil Engineering Landmark in 2017. Early history The Eupalinian aqueduct is described by Herodotus (''Histories'' 3.60), without whom it might not have been discovered: :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 i ...

Geraneia
Geraneia Mountains or Yerania Ori ( el, Γεράνεια Όρη) are a mountain range in Corinthia and West Attica, Greece. Its highest point is the peak ''Makryplagi'' ( el, Μακρυπλάγι), 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 pack of Geraneia Mountains is the southernmost in Greece, possibly in Europe, too. Nearest places * Agioi Theodoroi, south * Megara, e ...

Ancient Megarians
Ancient history is a time period from the beginning of writing and recorded human history to as far as late antiquity. The span of recorded history is roughly 5,000 years, beginning with the Sumerian cuneiform script. Ancient history covers all continents inhabited by humans in the period 3000 BCAD 500. The three-age system periodizes 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 varies 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 already exponentially increasing due to the Neolithic Revolution, which was in full progress.

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. In its second Golden Age, the Sassanid Empire reached the peak of its power under Khosrau I in the 6th century.Roberts, J: "History of the World.". Penguin, 1994.

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 Athens ...

Corinth
Corinth ( ; el, Κόρινθος, Kórinthos, ) is the successor to an ancient city, and is a former municipality in Corinthia, Peloponnese, which is located in south-central Greece. Since the 2011 local government reform, it has been part of the municipality of Corinth, of which it is the seat and a municipal unit. It is the capital of Corinthia. It was founded as Nea Korinthos (), or New Corinth, in 1858 after an earthquake destroyed the existing settlement of Corinth, which had developed in and around the site of ancient Corinth. Geography Located about west of Athens, Corinth is surrounded by the coastal townlets of (clockwise) Lechaio, Isthmia, Kechries, and the inland townlets of Examilia and the archaeological site and village of ancient Corinth. Natural features around the city include the narrow coastal plain of Vocha, the Corinthian Gulf, the Isthmus of Corinth cut by its canal, the Saronic Gulf, the Oneia Mountains, and the monolithic rock of Acrocorinth ...

Athens
Athens ( ; el, Αθήνα, Athína ; grc, Ἀθῆναι, Athênai (pl.) ) is both the capital and largest city of Greece. With a population close to four million, it is also the seventh largest city in the European Union. Athens dominates and is the capital of the Attica region and is one of the world's oldest cities, with its recorded history spanning over 3,400 years and its earliest human presence beginning somewhere between the 11th and 7th millennia BC. Classical Athens was a powerful city-state. It was a centre for the arts, learning and philosophy, and the home of Plato's Academy and Aristotle's Lyceum. It is widely referred to as the cradle of Western civilization and the birthplace of democracy, largely because of its cultural and political influence on the European continent—particularly Ancient Rome. In modern times, Athens is a large cosmopolitan metropolis and central to economic, financial, industrial, maritime, political and cultural life in Gre ...

Corinthia
Corinthia ( el, Κορινθία ''Korinthía'') is one of the regional units of Greece. It is part of the region of 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 to the southwest. The Corinth Canal, carrying ship traffic between the Ionian and the 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 including the southeastern part are made up of fault lines including the Corinth Fault, the Poseidon Fault and a fault running from Perahcora to Agioi Theodoroi.

Road Tunnel
A tunnel is an underground passageway, dug through surrounding soil, earth or rock, and enclosed except for the entrance and exit, commonly at each end. A pipeline is not a tunnel, though some recent tunnels have used immersed tube construction techniques rather than traditional tunnel boring methods. A tunnel may be for foot or vehicular road traffic, for rail traffic, or for a canal. The central portions of a rapid transit network are usually in the tunnel. Some tunnels are used as sewers or aqueducts to supply water for consumption or for hydroelectric stations. Utility tunnels are used for routing steam, chilled water, electrical power or telecommunication cables, as well as connecting buildings for convenient passage of people and equipment. Secret tunnels are built for military purposes, or by civilians for smuggling of weapons, contraband, or people. Special tunnels, such as wildlife crossings, are built to allow wildlife to cross human-made barriers safely. Tu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
