Corbelled Vault
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 ( ), also called Great Skellig ( ), 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 species, which include gannets, puffins, a colony ...

Ugarit Corbel
Ugarit (; , ''ủgrt'' /ʾUgarītu/) was an ancient port city in northern Syria about 10 kilometers north of modern Latakia. At its height it ruled an area roughly equivalent to the modern Latakia Governorate. It was discovered by accident in 1928 with the Ugaritic texts. Its ruins are often called Ras Shamra after the headland where they lie. History Ugarit saw its beginnings in the Neolithic period, the site was occupied from the end of the 8th millennium BC and continued as a settlement through the Chalcolithic and Bronze Ages. It was during the late bronze age that Ugarit experienced significant growth, culminating in the establishment of the Kingdom of Ugarit. The city had close connections to the Hittite Empire, in later times as a vassal, sent tribute to Egypt at times, and maintained trade and diplomatic connections with Cyprus (then called Alashiya), documented in the archives recovered from the site and corroborated by Mycenaean and Cypriot pottery found there.

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 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 may be made using prestressed concrete and are also referred to as beams in beam-and-block slabs or as ribs in rib-and-block slabs. These prestressed concrete lintels and blocks can serve as components that are packed together and propped to form a suspended-floor concrete slab. An arch functions as a curved lintel. 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
True Arch
An arch is a curved vertical structure spanning an open space underneath it. Arches may support the load above them, or they may perform a purely decorative role. As a decorative element, the arch dates back to the 4th millennium BC, but structural load-bearing arches became popular only after their adoption by the Ancient Romans in the 4th century BC. Arch-like structures can be horizontal, like an arch dam that withstands the horizontal hydrostatic pressure load. Arches are usually used as supports for many types of vaults, with the barrel vault in particular being a continuous arch. Extensive use of arches and vaults characterizes an arcuated construction, as opposed to the trabeated system, where, like in the architectures of ancient Greece, China, and Japan (as well as the modern steel-framed technique), posts and beams dominate. Arches had several advantages over the lintel, especially in the masonry construction: with the same amount of material it can have large ...

Great Pyramid Of Giza
The Great Pyramid of Giza is the largest Egyptian pyramid. It served as the tomb of pharaoh Khufu, who ruled during the Fourth Dynasty of Egypt, Fourth Dynasty of the Old Kingdom of Egypt, Old Kingdom. Built , over a period of about 26 years, the pyramid is the oldest of the Seven Wonders of the Ancient World, and the only wonder that has remained largely intact. It is the most famous monument of the Giza pyramid complex, which is part of the World Heritage Site, UNESCO World Heritage Site "Memphis, Egypt, Memphis and its Memphite Necropolis, Necropolis". It is situated at the northeastern end of the line of the three main pyramids at Giza. Initially standing at , the Great Pyramid was the world's List of tallest buildings and structures#History, tallest human-made structure 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 current ; what is seen today is the underlying core structure. The ba ...

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 of four built by Old Kingdom Pharaoh Sneferu, and was built 2575–2563 BCE. The Red Pyramid is located approximately 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 south of Cairo, built under the Old Kingdom King Sneferu. A unique example of early pyramid development in Ancient Egypt, Egypt, this was the second of four pyramids built by Sneferu. The Bent Pyramid rises from the desert at a 54-degree inclination, but the top section (above ) 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 change from the Step pyramid, step-sided pyramids of before to smooth-sided Pyramid, 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 born out by the fact that the adjacent Red Pyramid, built immediately ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Meidum
Meidum, Maydum or Maidum (, , ) 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 of four built by Sneferu 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 pyramid was erected in three phases, numbered E1, E2 and E3 by the archaeologist Borchardt. E1 was a step pyramid similar to the Djoser Pyramid. E2 was an extension around the previous building of roughly 5 m width or 10 cubits, raising the number of steps from 5 to 7. The second extension, E3, turned the original step pyramid design into a true pyramid by fill ... [...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 the central rituals of Egyptian religion: giving offerings to the gods, reenacting their mythology 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. Caring for the gods was the obligations of pharaohs, who dedicated prodigious resources to temple construction and maintenance. Pharaohs delegated most of their ritual duties to 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 religious site for all classes of Egyptians, who went there to pray, give offerings, and se ...

Pyramid
A pyramid () is a structure whose visible surfaces are triangular in broad outline and converge toward the top, making the appearance roughly a pyramid in the geometric sense. The base of a pyramid can be of any polygon shape, such as triangular or quadrilateral, and its surface-lines either filled or stepped. A pyramid has the majority of its mass closer to the ground with less mass towards the pyramidion at the apex. This is due to the gradual decrease in the cross-sectional area along the vertical axis with increasing elevation. This offers a weight distribution that allowed early civilizations to create monumental structures.Ancient civilizations in many parts of the world pioneered the building of pyramids. The largest pyramid by volume is the Mesoamerican Great Pyramid of Cholula, in the Mexican state of Puebla. For millennia, the largest structures on Earth were pyramids—first the Red Pyramid in the Dashur Necropolis and then the Great Pyramid of Khufu, bot ...

Ancient Egypt
Ancient Egypt () was a cradle of civilization concentrated along the lower reaches of the Nile River in Northeast Africa. It emerged from prehistoric Egypt around 3150BC (according to conventional Egyptian chronology), when Upper and Lower Egypt were amalgamated by Menes, who is believed by the majority of List of Egyptologists, Egyptologists to have been the same person as Narmer. The history of ancient Egypt unfolded as a series of stable kingdoms interspersed by the "Periodization of ancient Egypt, Intermediate Periods" of relative instability. These stable kingdoms existed in one of three periods: the Old Kingdom of Egypt, Old Kingdom of the Early Bronze Age; the Middle Kingdom of Egypt, Middle Kingdom of the Middle Bronze Age; or the New Kingdom of Egypt, New Kingdom of the Late Bronze Age. The pinnacle of ancient Egyptian power was achieved during the New Kingdom, which extended its rule to much of Nubia and a considerable portion of the Levant. After this period, Egypt ...
