Corbelled Arch
A corbel arch (or corbeled / corbelled arch) is an arch-like construction method that uses the architectural technique of corbeling to span a space or void in a structure, such as an entranceway in a wall or as the span of a bridge. A corbel vault uses this technique to support the superstructure of a building's roof. A corbel arch is constructed by offsetting successive horizontal courses of stone (or brick) beginning at the springline of the walls (the point at which the walls break off from verticality to form an arc toward the apex at the archway's center) so that they project towards the archway's center from each supporting side, until the courses meet at the apex of the archway (often, the last gap is bridged with a flat stone). For a corbeled vault covering, the technique is extended in three dimensions along the lengths of two opposing walls. Although an improvement in load-bearing efficiency over the post and lintel design, corbeled arches are not entirely self-supporti ...

Skellig Michael
Skellig Michael ( ga, Sceilg Mhichíl ), also called Great Skellig ( ga, link=no, Sceilig Mhór ), is a twin-pinnacled crag west of the Iveragh Peninsula in County Kerry, Ireland. The island is named after the archangel Michael, with "Skellig" derived from the Irish language word , meaning a splinter of stone. Its twin island, Little Skellig (), is smaller and inaccessible (landing is not permitted). The two islands rose c. 374–360 million years ago during a period of mountain formation, along with the MacGillycuddy's Reeks mountain range. Later, they were separated from the mainland by rising water levels. Skellig Michael consists of approximately of rock, with its highest point, known as the Spit, above sea level. The island is defined by its twin peaks and intervening valley (known as Christ's Saddle), which make its landscape steep and inhospitable. It is best known for its Gaelic monastery, founded between the 6th and 8th centuries, and its variety of inhabiting spec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ebla
Ebla ( Sumerian: ''eb₂-la'', ar, إبلا, modern: , Tell Mardikh) was one of the earliest kingdoms in Syria. Its remains constitute a tell located about southwest of Aleppo near the village of Mardikh. Ebla was an important center throughout the and in the first half of the Its discovery proved the Levant was a center of ancient, centralized civilization equal to Egypt and Mesopotamia and ruled out the view that the latter two were the only important centers in the Near East during the Early Bronze Age. The first Eblaite kingdom has been described as the first recorded world power. Starting as a small settlement in the Early Bronze Age ( ), Ebla developed into a trading empire and later into an expansionist power that imposed its hegemony over much of northern and eastern Syria. Ebla was destroyed during the It was then rebuilt and was mentioned in the records of the Third Dynasty of Ur. The second Ebla was a continuation of the first, ruled by a new royal d ...

History Of The Ancient Levant
The Levant is the area in Southwest Asia, south of the Taurus Mountains, bounded by the Mediterranean Sea in the west, the Arabian Desert in the south, and Mesopotamia in the east. It stretches north to south from the Taurus Mountains to the Sinai desert, and east to west between the sea and the Arabian desert. The term is also sometimes used to refer to modern events or states in the region immediately bordering the eastern Mediterranean Sea: the Hatay Province of Turkey, Cyprus, Syria, Lebanon, Palestine, and Jordan. The term normally does not include Anatolia (although at times Cilicia may be included), the Caucasus Mountains, Mesopotamia or any part of the Arabian Peninsula proper. The Sinai Peninsula is sometimes included, though it is more considered an intermediate, peripheral or marginal area forming a land bridge between the Levant and northern Egypt.

Lintel
A lintel or lintol is a type of beam (a horizontal structural element) that spans openings such as portals, doors, windows and fireplaces. It can be a decorative architectural element, or a combined ornamented structural item. In the case of windows, the bottom span is instead referred to as a sill, but, unlike a lintel, does not serve to bear a load to ensure the integrity of the wall. Modern day lintels are made using prestressed concrete and are also referred to as beams in beam and block slabs or ribs in rib and block slabs. These prestressed concrete lintels and blocks are components that are packed together and propped to form a suspended floor concrete slab. Structural uses In worldwide architecture of different eras and many cultures, a lintel has been an element of post and lintel construction. Many different building materials have been used for lintels. In classical Western architecture and construction methods, by ''Merriam-Webster'' definition, a lintel is a l ...

Great Pyramid Of Giza
The Great Pyramid of Giza is the biggest Egyptian pyramid and the tomb of Fourth Dynasty pharaoh Khufu. Built in the early 26th century BC during a period of around 27 years, the pyramid is the oldest of the Seven Wonders of the Ancient World, and the only one to remain largely intact. As part of the Giza pyramid complex, it borders present-day Giza in Greater Cairo, Egypt. Initially standing at , the Great Pyramid was the tallest man-made structure in the world for more than 3,800 years. Over time, most of the smooth white limestone casing was removed, which lowered the pyramid's height to the present . What is seen today is the underlying core structure. The base was measured to be about square, giving a volume of roughly , which includes an internal hillock. The dimensions of the pyramid were high, a base length of , with a seked of palms (a slope of 51°50'40"). The Great Pyramid was built by quarrying an estimated 2.3 million large blocks weighing 6 million tonnes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Red Pyramid
The Red Pyramid, also called the North Pyramid, is the largest of the pyramids located at the Dahshur necropolis in Cairo, Egypt. Named for the rusty reddish hue of its red limestone stones, it is also the third largest Egyptian pyramid, after those of Khufu and Khafre at Giza. It is also believed to be Egypt's first successful attempt at constructing a "true" smooth-sided pyramid. Local residents refer to the Red Pyramid as ''el-heram el-watwaat'', meaning the Bat Pyramid. The Red Pyramid was not always red. It used to be cased with white Tura limestone, but only a few of these stones now remain at the pyramid's base, at the corner. During the Middle Ages much of the white Tura limestone was taken for buildings in Cairo, revealing the red limestone beneath. History The Red Pyramid was the third pyramid built by Old Kingdom Pharaoh Sneferu, and was built 2575–2551 BCE. The Red Pyramid is located approximately one kilometer to the north of the Bent Pyramid. It is built at the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bent Pyramid
The Bent Pyramid is an ancient Egyptian pyramid located at the royal necropolis of Dahshur, approximately 40 kilometres south of Cairo, built under the Old Kingdom Pharaoh Sneferu (c. 2600 BC). A unique example of early pyramid development in Egypt, this was the second pyramid built by Sneferu. The Bent Pyramid rises from the desert at a 54-degree inclination, but the top section (above 47 metres) is built at the shallower angle of 43 degrees, lending the pyramid a visibly 'bent' appearance. Overview Archaeologists now believe that the Bent Pyramid represents a transitional form between step-sided and smooth-sided pyramids. It has been suggested that due to the steepness of the original angle of inclination the structure may have begun to show signs of instability during construction, forcing the builders to adopt a shallower angle to avert the structure's collapse. This theory appears to be borne out by the fact that the adjacent Red Pyramid, built immediately afterwards by th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Meidum
Meidum, Maydum or Maidum ( ar, ميدوم, , ) is an archaeological site in Lower Egypt. It contains a large pyramid and several mudbrick mastabas. The pyramid was Egypt's first straight-sided one, but it partially collapsed in ancient times. The area is located around south of modern Cairo. Pyramid The pyramid at Meidum is thought to be just the second pyramid built after Djoser's and may have been originally built for Huni, the last pharaoh of the Third Dynasty, and continued by Sneferu. Because of its unusual appearance, the pyramid is called ''el-heram el-kaddaab'' – (''False Pyramid'') in Egyptian Arabic. The second extension turned the original step pyramid design into a true pyramid by filling in the steps with limestone encasing. While this approach is consistent with the design of the other true pyramids, Meidum was affected by construction errors. Firstly, the outer layer was founded on sand and not on rock, like the inner layers. Secondly, the inner step pyram ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Egyptian Temple
Egyptian temples were built for the official worship of the gods and in commemoration of the pharaohs in ancient Egypt and regions under Egyptian control. Temples were seen as houses for the gods or kings to whom they were dedicated. Within them, the Egyptians performed a variety of rituals, the central functions of Egyptian religion: giving offerings to the gods, reenacting their mythological interactions through festivals, and warding off the forces of chaos. These rituals were seen as necessary for the gods to continue to uphold ''maat'', the divine order of the universe. Housing and caring for the gods were the obligations of pharaohs, who therefore dedicated prodigious resources to temple construction and maintenance. Out of necessity, pharaohs delegated most of their ritual duties to a host of priests, but most of the populace was excluded from direct participation in ceremonies and forbidden to enter a temple's most sacred areas. Nevertheless, a temple was an important r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pyramid
A pyramid (from el, πυραμίς ') is a structure whose outer surfaces are triangular and converge to a single step at the top, making the shape roughly a pyramid in the geometric sense. The base of a pyramid can be trilateral, quadrilateral, or of any polygon shape. As such, a pyramid has at least three outer triangular surfaces (at least four faces including the base). The square pyramid, with a square base and four triangular outer surfaces, is a common version. A pyramid's design, with the majority of the weight closer to the ground and with the pyramidion at the apex, means that less material higher up on the pyramid will be pushing down from above. This distribution of weight allowed early civilizations to create stable monumental structures. Civilizations in many parts of the world have built pyramids. The largest pyramid by volume is the Great Pyramid of Cholula, in the Mexican state of Puebla. For thousands of years, the largest structures on Earth were pyrami ...
