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 pyramids ...

Great Pyramid Of Giza
The Great Pyramid of Giza is the biggest Egyptian pyramids, Egyptian pyramid and the tomb of Fourth Dynasty of Egypt, 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 List of tallest buildings and structures#History, 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 Pyr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dashur Necropolis
DahshurAlso transliterated ''Dahshour'' (in English often called ''Dashur'' ar, دهشور ' , ''Dahchur'') is a royal necropolis located in the desert on the west bank of the Nile approximately south of Cairo. It is known chiefly for several pyramids, two of which are among the oldest, largest and best preserved in Egypt, built from 2613 to 2589 BC. Pyramids The Dahshur pyramids were an extremely important learning experience for the Egyptians. It provided them with the knowledge and know-how to transition from step-sided pyramids to smooth-sided pyramids. Ultimately their breadth of experience would allow them to build the Great Pyramid of Giza; the last of the Seven Wonders of the Ancient World still standing to this date. The first of the Dahshur pyramids was the Bent Pyramid (2613–2589 BC), built under the rule of King Sneferu. The Bent Pyramid was the first attempt at building a smooth sided pyramid, but proved to be an unsuccessful build due to the miscalculati ...

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 t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Great Pyramid Of Cholula
The Great Pyramid of Cholula, also known as (Nahuatl for "made-by-hand mountain"), is a complex located in Cholula, Puebla, Mexico. It is the largest archaeological site of a pyramid (temple) in the New World, as well as the largest pyramid by volume known to exist in the world today.Coe & Koontz 1962, 2002, p. 120. The adobe brick pyramid stands above the surrounding plain, which is significantly shorter than the Great Pyramid of Giza's height of , but much wider, measuring in its final form, compared to the Great Pyramid's base dimensions of . The pyramid is a temple that traditionally has been viewed as having been dedicated to the god Quetzalcoatl.Coe & Koontz 1962, 2002, p. 121. The architectural style of the building was linked closely to that of Teotihuacan in the Valley of Mexico, although influence from the Gulf Coast is evident as well, especially from El Tajín.Davies 1982, 1990, p. 92.

Khufu
Khufu or Cheops was an ancient Egyptian monarch who was the second pharaoh of the Fourth Dynasty, in the first half of the Old Kingdom period ( 26th century BC). Khufu succeeded his father Sneferu as king. He is generally accepted as having commissioned the Great Pyramid of Giza, one of the Seven Wonders of the Ancient World, but many other aspects of his reign are poorly documented. The only completely preserved portrait of the king is a three-inch high ivory figurine found in a temple ruin of a later period at Abydos in 1903. All other reliefs and statues were found in fragments, and many buildings of Khufu are lost. Everything known about Khufu comes from inscriptions in his necropolis at Giza and later documents. For example, Khufu is the main character noted in the Westcar Papyrus from the 13th dynasty. Most documents that mention king Khufu were written by ancient Egyptian and Greek historians around 300 BC. Khufu's obituary is presented there in a conflicting ...

Pyramidion
A pyramidion (plural: pyramidia) is the uppermost piece or capstone of an Egyptian pyramid or obelisk. Speakers of the Ancient Egyptian language referred to pyramidia as ''benbenet'' and associated the pyramid as a whole with the sacred benben stone.Toby Wilkinson, ''The Thames and Hudson Dictionary of Ancient Egypt'', Thames & Hudson, 2005. p. 197 During Egypt's Old Kingdom, pyramidia were generally made of diorite, granite, or fine limestone, then covered in gold or electrum; during the Middle Kingdom and through the end of the pyramid-building era, they were built from granite. A pyramidion was "covered in gold leaf to reflect the rays of the sun"; during Egypt's Middle Kingdom pyramidia were often "inscribed with royal titles and religious symbols". Very few pyramidia have survived into modern times. Most of those that remain are made of polished black granite, inscribed with the name of the pyramid's owner. Four pyramidia – the world's largest collection – are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pyramid (geometry)
In geometry, a pyramid () is a polyhedron formed by connecting a polygonal base and a point, called the apex. Each base edge and apex form a triangle, called a ''lateral face''. It is a conic solid with polygonal base. A pyramid with an base has vertices, faces, and edges. All pyramids are self-dual. A right pyramid has its apex directly above the centroid of its base. Nonright pyramids are called oblique pyramids. A regular pyramid has a regular polygon base and is usually implied to be a ''right pyramid''. When unspecified, a pyramid is usually assumed to be a ''regular'' square pyramid, like the physical pyramid structures. A triangle-based pyramid is more often called a tetrahedron. Among oblique pyramids, like acute and obtuse triangles, a pyramid can be called ''acute'' if its apex is above the interior of the base and ''obtuse'' if its apex is above the exterior of the base. A right-angled pyramid has its apex above an edge or vertex of the base. In a tetrah ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Seven Wonders Of The Ancient World
The Seven Wonders of the Ancient World, also known as the Seven Wonders of the World or simply the Seven Wonders, is a list of seven notable structures present during classical antiquity. The first known list of seven wonders dates back to the 2nd–1st century BC. While the entries have varied over the centuries, the seven traditional wonders are the Great Pyramid of Giza, the Colossus of Rhodes, the Lighthouse of Alexandria, the Mausoleum at Halicarnassus, the Temple of Artemis, the Statue of Zeus at Olympia, and the Hanging Gardens of Babylon. Using modern-day countries, two of the wonders were located in Greece, two in Turkey, two in Egypt, and one in Iraq. Of the seven wonders, only the Pyramid of Giza, which is also by far the oldest of the wonders, still remains standing, with the others being destroyed over the centuries. There is scholarly debate over the exact nature of the Hanging Gardens, and there is doubt as to whether they existed at all. Background Alexander t ...

Puebla
Puebla ( en, colony, settlement), officially Free and Sovereign State of Puebla ( es, Estado Libre y Soberano de Puebla), is one of the 32 states which comprise the Federal Entities of Mexico. It is divided into 217 municipalities and its capital is the city of Puebla. It is located in East-Central Mexico. It is bordered by the states of Veracruz to the north and east, Hidalgo, México, Tlaxcala and Morelos to the west, and Guerrero and Oaxaca to the south. The origins of the state lie in the city of Puebla, which was founded by the Spanish in this valley in 1531 to secure the trade route between Mexico City and the port of Veracruz. By the end of the 18th century, the area had become a colonial province with its own governor, which would become the State of Puebla, after the Mexican War of Independence in the early 19th century. Since that time the area, especially around the capital city, has continued to grow economically, mostly through industry, despite being the sce ...

Ziggurat
A ziggurat (; Cuneiform: 𒅆𒂍𒉪, Akkadian: ', D-stem of ' 'to protrude, to build high', cognate with other Semitic languages like Hebrew ''zaqar'' (זָקַר) 'protrude') is a type of massive structure built in ancient Mesopotamia. It has the form of a terraced compound of successively receding storeys or levels. Notable ziggurats include the Great Ziggurat of Ur near Nasiriyah, the Ziggurat of Aqar Quf near Baghdad, the now destroyed Etemenanki in Babylon, Chogha Zanbil in Khūzestān and Sialk Plus, Sumer in general. The Sumerians believed that the Gods lived in the temple at the top of the Ziggurats, so only priests and other highly respected individuals could enter. Society offered them many things such as music, harvest, and creating devotional statues to live in the temple. History The word ziggurat comes from ''ziqqurratum'' (height, pinnacle), in ancient Assyrian. From ''zaqārum'', to be high up. The Ziggurat of Ur is a Neo-Sumerian ziggurat built by King Ur-Na ...
