Zaghouan Aqueduct
The Zaghouan Aqueduct or Aqueduct of Carthage is an ancient Roman aqueduct, which supplied the city of Carthage, Tunisia with water. From its source in Zaghouan it flows a total of 132 km, making it among the longest aqueducts in the Roman Empire. Some of its length (40 ha area) is also classified as an Important Bird Area (TN013) as the cavities and holes in the aqueduct are used as nesting and roosting sites for falcons and other species. Date The date of the construction of the aqueduct is not entirely clear. Sources mention a visit by the Emperor Hadrian in 128, with which a five-year-long drought is meant to have come to an end. The water shortage resulting from the drought might have convinced him that the people should not rely only on rainwater anymore. A second event that might have inspired it was the opening of the Baths of Antonius in Carthage in 162. These facilities on the same scale as the Imperial baths in Rome demanded a steady supply of water, which cou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zaghouan
Zaghouan (or Zaghwan; , ) is a town in the northern half of Tunisia. Situated on a low ridge of the Dorsale Mountains, the town has a mild climate and presents a green aspect. Cold water from here was taken by the Zaghouan Aqueduct to Carthage. The town is famous for its roses, originally cultivated by Muslim refugees from Spain in the seventeenth century. The town is located around 60 km due south of Tunis and around 50 km inland (west) from the Gulf of Hammamet and has an estimated population of around 20,837 (2014). It is the capital of the Zaghouan Governorate. On the mountain south of the city is the Roman Water Temple Djebel Zaghouan (Temple de Eaux), source of an aqueduct which used to take water to the city of Carthage over 100 km away. The ruins here are illustrated in Fisher's Drawing Room Scrap Book, 1840, as 'Temple and Fountain of Zagwhan', the painting being by Sir Greenville Temple with a poetical illustration by Letitia Elizabeth Landon. ...

Sandstone
Sandstone is a Clastic rock#Sedimentary clastic rocks, clastic sedimentary rock composed mainly of grain size, sand-sized (0.0625 to 2 mm) silicate mineral, silicate grains, Cementation (geology), cemented together by another mineral. Sandstones comprise about 20–25% of all sedimentary rocks. Most sandstone is composed of quartz or feldspar, because they are the most resistant minerals to the weathering processes at the Earth's surface. Like uncemented sand, sandstone may be imparted any color by impurities within the minerals, but the most common colors are tan, brown, yellow, red, grey, pink, white, and black. Because sandstone beds can form highly visible cliffs and other topography, topographic features, certain colors of sandstone have become strongly identified with certain regions, such as the red rock deserts of Arches National Park and other areas of the Southwestern United States, American Southwest. Rock formations composed of sandstone usually allow the p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Battle Of Carthage (439)
Carthage was captured by the Vandals from the Western Roman Empire on 19 October 439. Under their leader Genseric, the Vandals crossed the Strait of Gibraltar into Africa and captured Hippo Regius in August 431, which they made the capital of their kingdom. Despite an uneasy peace with the Romans, Genseric made a surprise attack against Carthage in October 439. After capturing Carthage, the Vandals put the city to the sack and made it the new capital of their kingdom. Background In Gaul In 406, the Vandals advanced from Pannonia travelling west along the Danube without much difficulty, but when they reached the Rhine, they met resistance from the Franks, who populated and controlled Romanized regions in northern Gaul. Twenty thousand Vandals, including Godigisel, died in the resulting battle, but then with the help of the Alans they managed to defeat the Franks, and on December 31, 406 the Vandals crossed the Rhine to invade Gaul, which they devastated terribly.

Vandal
The Vandals were a Germanic people who were first reported in the written records as inhabitants of what is now Poland, during the period of the Roman Empire. Much later, in the fifth century, a group of Vandals led by kings established Vandal Kingdom, Vandal kingdoms first within the Iberian Peninsula, and then in the western Mediterranean islands, and North Africa. Archaeologists associate the early Vandals with the Przeworsk culture, which has led to some authors equating them to the Lugii, who were another group of Germanic peoples associated with that same archaeological culture and region. Expanding into Roman Dacia, Dacia during the Marcomannic Wars and to Pannonia during the Crisis of the Third Century, the Vandals were confined to Pannonia by the Goths around 330 AD, where they received permission to settle from Constantine the Great. Around 400, raids by the Huns from the east forced many Germanic tribes to migrate west into the territory of the Roman Empire and, fear ...

Mortar (masonry)
Mortar is a workable paste which hardens to bind building blocks such as stones, bricks, and concrete masonry units, to fill and seal the irregular gaps between them, spread the weight of them evenly, and sometimes to add decorative colours or patterns to masonry walls. In its broadest sense, mortar includes pitch, asphalt, and soft clay, as those used between bricks, as well as cement mortar. The word "mortar" comes from the Old French word ''mortier'', "builder's mortar, plaster; bowl for mixing." (13c.). Cement mortar becomes hard when it cures, resulting in a rigid aggregate (composite) , aggregate structure; however, the mortar functions as a weaker component than the building blocks and serves as the sacrificial element in the masonry, because mortar is easier and less expensive to repair than the building blocks. Bricklayers typically make mortars using a mixture of sand, a binder, and water. The most common binder since the early 20th century is Portland cement, but ...

Cistern
A cistern (; , ; ) is a waterproof receptacle for holding liquids, usually water. Cisterns are often built to catch and store rainwater. To prevent leakage, the interior of the cistern is often lined with hydraulic plaster. Cisterns are distinguished from wells by their waterproof linings. Modern cisterns range in capacity from a few liters to thousands of cubic meters, effectively forming covered reservoirs. Origins Early domestic and agricultural use Waterproof lime plaster cisterns in the floors of houses are features of Neolithic village sites of the Levant at, for instance, Ramad and Lebwe, and by the late fourth millennium BC, as at Jawa in northeastern Lebanon, cisterns are essential elements of emerging water management techniques in dry-land farming communities. Early examples of ancient cisterns, found in Israel, include a significant discovery at Tel Hazor, where a large cistern was carved into bedrock beneath a palace dating to the Late Bronze Age.

Carthage Aqueducts 2
Carthage was an ancient city in Northern Africa, on the eastern side of the Lake of Tunis in what is now Tunisia. Carthage was one of the most important trading hubs of the Ancient Mediterranean and one of the most affluent cities of the classical world. It became the capital city of the civilization of Ancient Carthage and later Roman Carthage. The city developed from a Phoenician colony into the capital of a Punic empire which dominated large parts of the Southwest Mediterranean during the first millennium BC. The legendary Queen Elissa, Alyssa or Dido, originally from Tyre, is regarded as the founder of the city, though her historicity has been questioned. In the myth, Dido asked for land from a local tribe, which told her that she could get as much land as an oxhide could cover. She cut the oxhide into strips and laid out the perimeter of the new city. As Carthage prospered at home, the polity sent colonists abroad as well as magistrates to rule the colonies.

Screed
Screed has three meanings in building construction: # A flat board (screed board, floating screed) or a purpose-made aluminium tool used to smooth and to "Wikt:true#Verb, true" materials like concrete, stucco and plaster after they have been placed on a surface or to assist in flattening; # A strip of plaster or wood applied to a surface to act as a guide for a screed tool (screed rail, screed strip, screed batten); # The material itself which has been flattened with a screed (screed coat). In the UK, ''screed'' has also come to describe a thin, top layer of material (sand and cement, magnesite or calcium sulphate), poured in place on top of the structural concrete or insulation, on top of which other finishing materials can be applied, or the structural material can be left bare to achieve a raw effect. Screed board In the United States, a person called a concrete finisher performs the process of screeding, which is the process of cutting off excess wet concrete to bring ...

Opus Signinum
''Opus signinum'' ('cocciopesto' in modern Italian) is a building material used in ancient Rome. It is a form of Roman concrete (''opus caementicium''), the main difference being the addition of small pieces of broken pot, including ''amphorae'', tiles or brick, instead of other aggregates. Its main advantage over ''opus caementicium'' was that it is waterproof, the reason for its widespread use in Roman baths, aqueducts, cisterns and any buildings involving water. In floors it provided damp-proofing. Pliny the Elder describes its manufacture: Pliny's use of the term ''signine'' references Signia (modern Segni), the town in Latium which was famous for its tiles. Origins, spread, disuse The technique, most probably invented by the Phoenicians, is documented in the early 7th cent. BC at Tell el-Burak (Lebanon), then in Phoenician colonies in North Africa, some time before 256 BC, and spread north from there to Sicily and finally to the Italian peninsula.

Arcade (architecture)
An arcade is a succession of contiguous arches, with each arch supported by a colonnade of columns or Pier (architecture), piers. Exterior arcades are designed to provide a sheltered walkway for pedestrians; they include many loggias, but here arches are not an essential element. An arcade may feature arches on both sides of the walkway. Alternatively, a blind arcade superimposes arcading against a solid wall. Blind arcades are a feature of Romanesque architecture that influenced Gothic architecture. In the Gothic architectural tradition, the arcade can be located in the interior, in the lowest part of the wall of the nave, supporting the triforium and the clerestory in a cathedral, or on the exterior, in which they are usually part of the walkways that surround the courtyard and cloisters. A different, related meaning is "a covered passage with shops on one or both sides". Many medieval open arcades housed shops or stalls, either in the arcaded space itself, or set into the mai ...

Adduction Zaghouan Tunis
Motion, the process of movement, is described using specific anatomical terms. Motion includes movement of organs, joints, limbs, and specific sections of the body. The terminology used describes this motion according to its direction relative to the anatomical position of the body parts involved. Anatomists and others use a unified set of terms to describe most of the movements, although other, more specialized terms are necessary for describing unique movements such as those of the hands, feet, and eyes. In general, motion is classified according to the anatomical plane it occurs in. ''Flexion'' and ''extension'' are examples of ''angular'' motions, in which two axes of a joint are brought closer together or moved further apart. ''Rotational'' motion may occur at other joints, for example the shoulder, and are described as ''internal'' or ''external''. Other terms, such as ''elevation'' and ''depression'', describe movement above or below the horizontal plane. Many anatomical ...
