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. 40 ha of its length are 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 could not be fu ...

Zaghouan
Zaghouan (or Zaghwan; ar, زغوان '' ; ber, ⵣⴻⵖⵡⴰⵏ / Zeɣwan)'' 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 subject of a poem by Letitia Elizabeth Landon. E ...

Sandstone
Sandstone is a clastic sedimentary rock composed mainly of sand-sized (0.0625 to 2 mm) silicate grains. Sandstones comprise about 20–25% of all sedimentary rocks. Most sandstone is composed of quartz or feldspar (both silicates) because they are the most resistant minerals to weathering processes at the Earth's surface. Like uncemented sand, sandstone may be any color due to impurities within the minerals, but the most common colors are tan, brown, yellow, red, grey, pink, white, and black. Since sandstone beds often form highly visible cliffs and other topographic features, certain colors of sandstone have been strongly identified with certain regions. Rock formations that are primarily composed of sandstone usually allow the percolation of water and other fluids and are porous enough to store large quantities, making them valuable aquifers and petroleum reservoirs. Quartz-bearing sandstone can be changed into quartzite through metamorphism, usually related to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eastern Roman Empire
The Byzantine Empire, also referred to as the Eastern Roman Empire or Byzantium, was the continuation of the Roman Empire primarily in its eastern provinces during Late Antiquity and the Middle Ages, when its capital city was Constantinople. It survived the fragmentation and fall of the Western Roman Empire in the 5th century AD and continued to exist for an additional thousand years until the fall of Constantinople to the Ottoman Empire in 1453. During most of its existence, the empire remained the most powerful economic, cultural, and military force in Europe. The terms "Byzantine Empire" and "Eastern Roman Empire" were coined after the end of the realm; its citizens continued to refer to their empire as the Roman Empire, and to themselves as Romans—a term which Greeks continued to use for themselves into Ottoman times. Although the Roman state continued and its traditions were maintained, modern historians prefer to differentiate the Byzantine Empire from Ancient Rome a ...

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 himself, 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, probably while it was frozen, to invade Gaul, whi ...

Vandal
The Vandals were a Germanic people who first inhabited what is now southern Poland. They established Vandal kingdoms on the Iberian Peninsula, Mediterranean islands, and North Africa in the fifth century. The Vandals migrated to the area between the lower Oder and Vistula rivers in the second century BC and settled in Silesia from around 120 BC. They are associated with the Przeworsk culture and were possibly the same people as the Lugii. Expanding into 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, fearing that they might be targeted next, the Vandals were also pushed westwards, crossing the Rhine into Gaul along with other tribes in 406. In 409, the Vandals crossed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 colors or patterns to masonry walls. In its broadest sense, mortar includes pitch, asphalt, and soft mud or clay, as those used between mud bricks, as well as cement mortar. The word "mortar" comes from Old French ''mortier'', "builder's mortar, plaster; bowl for mixing." (13c.). Cement mortar becomes hard when it cures, resulting in a rigid 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 the ancient binder lim ...

Cistern
A cistern (Middle English ', from Latin ', from ', "box", from Greek ', "basket") is a waterproof receptacle for holding liquids, usually water. Cisterns are often built to catch and store rainwater. Cisterns are distinguished from wells by their waterproof linings. Modern cisterns range in capacity from a few litres to thousands of cubic metres, 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. The Ancient Roman impluvium, a standard feature of the domus house, generally had a cistern underneath. The impluvium and associated structures collected, filtered, cooled, and stored the water, and also cooled and ventilated ...

Carthage Aqueducts 2
Carthage was the capital city of Ancient Carthage, 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. The city developed from a Canaanite 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 Alyssa or Dido, originally from Tyre, is regarded as the founder of the city, though her historicity has been questioned. According to accounts by Timaeus of Tauromenium, she purchased from a local tribe the amount of land that could be covered by an oxhide. As Carthage prospered at home, the polity sent colonists abroad as well as magistrates to rule the colonies. The ancient city was destroyed in the nearly-three year siege of Carthage by the Roman Republic during the Third Punic War in 146 BC and then re-developed as Roman Car ...

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 "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 situ 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, screeding is the process a person called a concrete finisher performs by cutting off excess wet concrete to bring the top surface of a slab to the proper ...

Arcade (architecture)
An arcade is a succession of contiguous arches, with each arch supported by a colonnade of columns or piers. Exterior arcades are designed to provide a sheltered walkway for pedestrians. The walkway may be lined with retail stores. 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. Many medieval arcades housed shops or stalls, either in the arcaded space itself, or set into the main wall behind. From this, "arcade" has become a general word for a group of shops in a single building, regardless of the architectural f ...

Adduction Zaghouan Tunis
Motion, the process of movement, is described using specific anatomical terminology, anatomical terms. Motion includes movement of Organ (anatomy), organs, joints, Limb (anatomy), 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. Anatomy, 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'', descri ...
