Makestos Bridge
The Macestus Bridge or Bridge of Sultançayır was a Roman bridge across the Macestus River ( tr, Simav or ''Susurluk Çayı'') at Balıkesir, in the northwestern part of modern-day Turkey. Its flattened arches, slender piers and the hollow chamber system documented the progress made in late antique bridge building. A first cursory investigation of the 234 m long structure was conducted in the early 20th century, but since then its existence has been largely neglected by scholars. Current photos from 2009 show that the bridge has collapsed in the meantime. Exploration The bridge is located at Sultançayır, in the heart of the ancient region of Mysia, where it carried the road connecting Hadrianu Therai (''Balıkesir'') with Miletopolis across the Macestus. During an exploration tour in 1902, the German archaeologist Theodor Wiegand found the ancient structure still in an excellent state of preservation; only the fourth pier from the eastern bank had been blown up some th ...

Balıkesir
Balıkesir () is a city in Turkey and is the capital city of Balıkesir Province. Balıkesir is located in the Marmara region of Turkey and has a population of 338,936. Between 1341–1922, it was the capital of Karasi. History Close to modern Balıkesir was the Roman town of '' Hadrianutherae'', founded, as its name commemorates, by the emperor Hadrian. Hadrian came to the region in A.D. 124, as a result of a successful bear hunting he had established a city called his name here. It is estimated that the city consisted of the castle, the homestead, the stud and a few homes. It is thought that the small town was where the current stadium is present. Members of the Roman and Pre-Byzantine dynasty had used this castle as a vacation area and for hunting. During the Byzantine period, the small town which had become increasingly neglected was known as ''Palaeokastron'' ( el, Παλαιόκαστρο) meaning Old Castle. Also, when the Turkomans came from Middle Asia to Mysia, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Theodor Wiegand
Theodor Wiegand (October 30, 1864 – December 19, 1936) was one of the more famous German archaeologists. Wiegand was born in Bendorf, Rhenish Prussia. He studied at the universities of Munich, Berlin, and Freiburg. In 1894 he worked under Wilhelm Dörpfeld at the excavation of the Athenian Acropolis. From 1895 until 1899 he excavated the ancient Greek city of Priene, and from 1899 to 1911 he worked at Miletus. He took part in the excavations of the sanctuary of Didyma (1905–11) and of Samos (1910–11). In Pergamon he discovered, in 1927, the arsenals of the castle at the acropolis and excavated the large sanctuary of Asklepios outside the city. He also finished the excavations at Baalbek in Lebanon and published the results. From 1899 until 1911 he worked for the museums of Berlin as a foreign director in Constantinople, the capital of the Ottoman Empire, and was the science attaché of the German Embassy there. From 1912 to 1930 he worked as the director o ... [...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 ...

Ashlar
Ashlar () is finely dressed (cut, worked) stone, either an individual stone that has been worked until squared, or a structure built from such stones. Ashlar is the finest stone masonry unit, generally rectangular cuboid, mentioned by Vitruvius as opus isodomum, or less frequently trapezoidal. Precisely cut "on all faces adjacent to those of other stones", ashlar is capable of very thin joints between blocks, and the visible face of the stone may be quarry-faced or feature a variety of treatments: tooled, smoothly polished or rendered with another material for decorative effect. One such decorative treatment consists of small grooves achieved by the application of a metal comb. Generally used only on softer stone ashlar, this decoration is known as "mason's drag". Ashlar is in contrast to rubble masonry, which employs irregularly shaped stones, sometimes minimally worked or selected for similar size, or both. Ashlar is related but distinct from other stone masonry that is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Voussoir
A voussoir () is a wedge-shaped element, typically a stone, which is used in building an arch or vault. Although each unit in an arch or vault is a voussoir, two units are of distinct functional importance: the keystone and the springer. The keystone is the centre stone or masonry unit at the apex of an arch. The springer is the lowest voussoir on each side, located where the curve of the arch springs from the vertical support or abutment of the wall or pier. The keystone is often decorated or enlarged. An enlarged and sometimes slightly dropped keystone is often found in Mannerist arches of the 16th century, beginning with the works of Giulio Romano, who also began the fashion for using voussoirs above rectangular openings, rather than a lintel (Palazzo Stati Maccarani, Rome, circa 1522). The word is a stonemason's term borrowed in Middle English from French verbs connoting a "turn" (''OED''). Each wedge-shaped voussoir ''turns aside'' the thrust of the mass above, transf ...

Limestone
Limestone ( calcium carbonate ) is a type of carbonate sedimentary rock which is the main source of the material lime. It is composed mostly of the minerals calcite and aragonite, which are different crystal forms of . Limestone forms when these minerals precipitate out of water containing dissolved calcium. This can take place through both biological and nonbiological processes, though biological processes, such as the accumulation of corals and shells in the sea, have likely been more important for the last 540 million years. Limestone often contains fossils which provide scientists with information on ancient environments and on the evolution of life. About 20% to 25% of sedimentary rock is carbonate rock, and most of this is limestone. The remaining carbonate rock is mostly dolomite, a closely related rock, which contains a high percentage of the mineral dolomite, . ''Magnesian limestone'' is an obsolete and poorly-defined term used variously for dolomite, for limes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spandrel
A spandrel is a roughly triangular space, usually found in pairs, between the top of an arch and a rectangular frame; between the tops of two adjacent arches or one of the four spaces between a circle within a square. They are frequently filled with decorative elements. Meaning There are four or five accepted and cognate meanings of the term ''spandrel'' in architectural and art history, mostly relating to the space between a curved figure and a rectangular boundary – such as the space between the curve of an arch and a rectilinear bounding moulding, or the wallspace bounded by adjacent arches in an arcade and the stringcourse or moulding above them, or the space between the central medallion of a carpet and its rectangular corners, or the space between the circular face of a clock and the corners of the square revealed by its hood. Also included is the space under a flight of stairs, if it is not occupied by another flight of stairs. In a building with more than one floor ...

Aesepus Bridge
The Aesepus Bridge ( tr, Güvercin Köprüsü, "Dove Bridge") was a late antique Roman bridge over the Aesepus River (today ''Gönen Çayı'') in the ancient region of Mysia in modern-day Turkey. It is notable for its advanced hollow chamber system which has also been employed in other Roman bridges in the region, such as the Makestos Bridge. In a field examination carried out in the early 20th century, the four main vaults of the bridge were found in ruins, while nearly all piers and the seven minor arches had still remained intact. Today, the two remaining pier stubs in the riverbed are still extant, while the condition of the rest of the structure is difficult to determine. Location and dating The Aesepus Bridge is located in northwestern Turkey, 8 km north of Sariköy, approximately 5.6 km upstream of where the Gönen Çayı flows into the Sea of Marmara, slightly above the point where the narrow river valley opens into the wide estuary plain and a modern bridge ca ...

Asia Minor
Anatolia, tr, Anadolu Yarımadası), and the Anatolian plateau, also known as Asia Minor, is a large peninsula in Western Asia and the westernmost protrusion of the Asian continent. It constitutes the major part of modern-day Turkey. The region is bounded by the Turkish Straits to the northwest, the Black Sea to the north, the Armenian Highlands to the east, the Mediterranean Sea to the south, and the Aegean Sea to the west. The Sea of Marmara forms a connection between the Black and Aegean seas through the Bosporus and Dardanelles straits and separates Anatolia from Thrace on the Balkan peninsula of Southeast Europe. The eastern border of Anatolia has been held to be a line between the Gulf of Alexandretta and the Black Sea, bounded by the Armenian Highlands to the east and Mesopotamia to the southeast. By this definition Anatolia comprises approximately the western two-thirds of the Asian part of Turkey. Today, Anatolia is sometimes considered to be synonymous with Asia ...

Vault (architecture)
In architecture, a vault (French ''voûte'', from Italian ''volta'') is a self-supporting arched form, usually of stone or brick, serving to cover a space with a ceiling or roof. As in building an arch, a temporary support is needed while rings of voussoirs are constructed and the rings placed in position. Until the topmost voussoir, the keystone, is positioned, the vault is not self-supporting. Where timber is easily obtained, this temporary support is provided by centering consisting of a framed truss with a semicircular or segmental head, which supports the voussoirs until the ring of the whole arch is completed. Vault types Corbelled vaults, also called false vaults, with horizontally joined layers of stone have been documented since prehistoric times; in the 14th century BC from Mycenae. They were built regionally until modern times. The real vault construction with radially joined stones was already known to the Egyptians and Assyrians and was introduced into the buil ...

Classical Antiquity
Classical antiquity (also the classical era, classical period or classical age) is the period of cultural history between the 8th century BC and the 5th century AD centred on the Mediterranean Sea, comprising the interlocking civilizations of ancient Greece and ancient Rome known as the Greco-Roman world. It is the period in which both Greek and Roman societies flourished and wielded huge influence throughout much of Europe, North Africa, and Western Asia. Conventionally, it is taken to begin with the earliest-recorded Epic Greek poetry of Homer (8th–7th-century BC), and continues through the emergence of Christianity (1st century AD) and the fall of the Western Roman Empire (5th-century AD). It ends with the decline of classical culture during late antiquity (250–750), a period overlapping with the Early Middle Ages (600–1000). Such a wide span of history and territory covers many disparate cultures and periods. ''Classical antiquity'' may also refer to an idealized v ...

Keystone (architecture)
A keystone (or capstone) is the wedge-shaped stone at the apex of a masonry arch or typically round-shaped one at the apex of a vault. In both cases it is the final piece placed during construction and locks all the stones into position, allowing the arch or vault to bear weight. In arches and vaults (such as quasi-domes) keystones are often enlarged beyond the structural requirements and decorated. A variant in domes and crowning vaults is a lantern. Keystones, as a hallmark of strength or good architecture, or their suggested form are sometimes placed in the centre of the flat top of doors, recesses and windows for decorative effect, so as to form an upward projection of a lintel. Although a masonry arch or vault cannot be self-supporting until the keystone is placed, the keystone experiences the least stress of any of the voussoirs, due to its position at the apex. Old keystones can decay due to vibration, a condition known as bald arch. Architecture In a rib-vaulted c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
