Aqueduct (watercourse)
An aqueduct is a watercourse constructed to carry water from a source to a distribution point far away. In modern engineering, the term ''aqueduct'' is used for any system of pipes, ditches, canals, tunnels, and other structures used for this purpose. The term ''aqueduct'' also often refers specifically to a bridge carrying an artificial watercourse. Aqueducts were used in ancient Greece, ancient Egypt, and ancient Rome. The simplest aqueducts are small ditches cut into the earth. Much larger channels may be used in modern aqueducts. Aqueducts sometimes run for some or all of their path through tunnels constructed underground. Modern aqueducts may also use pipelines. Historically, agricultural societies have constructed aqueducts to irrigate crops and supply large cities with drinking water. Etymology The word ''aqueduct'' is derived from the Latin words (''water'') and (''led'' or ''guided''). Ancient aqueducts Although particularly associated with the Romans, aqueducts we ...

Hampi Aqueduct
Hampi or Hampe, also referred to as the Group of Monuments at Hampi, is a UNESCO World Heritage Site located in Hampi town, Vijayanagara district, east-central Karnataka, India. Hampi was the capital of the Vijayanagara Empire in the 14th century. It was a fortified city. Chronicles left by Persian and European travellers, particularly the Portuguese, say that Hampi was a prosperous, wealthy and grand city near the Tungabhadra River, with numerous temples, farms and trading markets. By 1500 CE, Hampi-Vijayanagara was the world's second-largest medieval-era city after Beijing, and probably India's richest at that time, attracting traders from Persia and Portugal. The Vijayanagara Empire was defeated by a coalition of Muslim sultanates; its capital was conquered, pillaged and destroyed by sultanate armies in 1565, after which Hampi remained in ruins. Located in Karnataka near the modern-era city of Hosapete, Hampi's ruins are spread over and it has been described by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polycrates
Polycrates (; grc-gre, Πολυκράτης), son of Aeaces, was the tyrant of Samos from the 540s BC to 522 BC. He had a reputation as both a fierce warrior and an enlightened tyrant. Sources The main source for Polycrates' life and activities is the historian Herodotus, who devotes a large section of book 3 of his '' Histories'' to the rise and fall of Polycrates (3.39-60, 3.120-126). His account was written in the third quarter of the 5th century BC, nearly a century after Polycrates' death, was based mostly on oral traditions and incorporates many folk-tale elements. Furthermore, Herodotus creatively shaped his account of Polycrates in order to make general moral points and to comment on the imperialism of the Athenian empire in his own day. Some poetry from Polycrates' time comments on him in passing and there is a smattering of references to Polycrates in other literary sources ranging in date from the 4th century BC to the Roman Imperial period. These sources preserve u ... [...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 ...

Samos
Samos (, also ; el, Σάμος ) is a Greek island in the eastern Aegean Sea, south of Chios, north of Patmos and the Dodecanese, and off the coast of western Turkey, from which it is separated by the -wide Mycale Strait. It is also a separate regional unit of the North Aegean region. In ancient times, Samos was an especially rich and powerful city-state, particularly known for its vineyards and wine production. It is home to Pythagoreion and the Heraion of Samos, a UNESCO World Heritage Site that includes the Eupalinian aqueduct, a marvel of ancient engineering. Samos is the birthplace of the Greek philosopher and mathematician Pythagoras, after whom the Pythagorean theorem is named, the philosophers Melissus of Samos and Epicurus, and the astronomer Aristarchus of Samos, the first known individual to propose that the Earth revolves around the sun. Samian wine was well known in antiquity and is still produced on the island. The island was governed by the semi-autonomous ...

Nabataean
The Nabataeans or Nabateans (; Nabataean Aramaic: , , vocalized as ; Arabic: , , singular , ; compare grc, Ναβαταῖος, translit=Nabataîos; la, Nabataeus) were an ancient Arab people who inhabited northern Arabia and the southern Levant. Their settlements—most prominently the assumed capital city of Raqmu (present-day Petra, Jordan)—gave the name ''Nabatene'' ( grc, Ναβατηνή, translit=Nabatēnḗ) to the Arabian borderland that stretched from the Euphrates to the Red Sea. The Nabateans emerged as a distinct civilization and political entity between the 4th and 2nd centuries BCE,Taylor, Jane (2001). ''Petra and the Lost Kingdom of the Nabataeans''. London: I.B.Tauris. pp. 14, 17, 30, 31. . Retrieved 8 July 2016. with their kingdom centered around a loosely controlled trading network that brought considerable wealth and influence across the ancient world.

Petra
Petra ( ar, ٱلْبَتْرَاء, Al-Batrāʾ; grc, Πέτρα, "Rock", Nabataean Aramaic, Nabataean: ), originally known to its inhabitants as Raqmu or Raqēmō, is an historic and archaeological city in southern Jordan. It is adjacent to the mountain of Jebel al-Madhbah, Jabal Al-Madbah, in a Depression (geology), basin surrounded by mountains forming the eastern flank of the Arabah valley running from the Dead Sea to the Gulf of Aqaba. The area around Petra has been inhabited from as early as 7000 BC, and the Nabataeans might have settled in what would become the capital city of Nabataean Kingdom, their kingdom as early as the 4th century BC. Archaeological work has only discovered evidence of Nabataean presence dating back to the second century BC, by which time Petra had become their capital. The Nabataeans were nomadic Arabs who invested in Petra's proximity to the incense trade routes by establishing it as a major regional trading hub. The trading business gained ...

Qanāt
A qanat or kārīz is a system for transporting water from an aquifer or water well to the surface, through an underground aqueduct; the system originated approximately 3,000 BC in what is now Iran. The function is essentially the same across North Africa and the Middle East but the system operates under a variety of regional names: ''qanat'' or kārīz in Iran, ''foggara'' in Algeria, ''khettara'' in Morocco, ''falaj'' in Oman, ''karez'' in Afghanistan, ''auyoun'' in Saudi Arabia, et al. The largest extant and functional qanat systems are located in Iran, Afghanistan, Oman, the oases of Turfan region of China, Algeria, and Pakistan. This is a system of water supply that allows water to be transported over long distances in hot dry climates without loss of much of the water to evaporation. The system has the advantage of being resistant to natural disasters such as earthquakes and floods, and to deliberate destruction in war. Furthermore, it is almost insensitive to the level ...
