Pyramid (television)
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 pyra ...

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] |
Akkadian Empire
The Akkadian Empire () was the first ancient empire of Mesopotamia after the long-lived civilization of Sumer. It was centered in the city of Akkad (city), Akkad () and its surrounding region. The empire united Akkadian language, Akkadian and Sumerian language, Sumerian speakers under one rule. The Akkadian Empire exercised influence across Mesopotamia, the Levant, and Anatolia, sending military expeditions as far south as Dilmun and Magan (civilization), Magan (modern Saudi Arabia, Bahrain, and Oman) in the Arabian Peninsula.Mish, Frederick C., Editor in Chief. "Akkad" ''Webster’s Ninth New Collegiate Dictionary''. ninth ed. Springfield, MA: Merriam-Webster 1985. ). The Akkadian Empire reached its political peak between the 24th and 22nd centuries BC, following the conquests by its founder Sargon of Akkad. Under Sargon and his successors, the Akkadian language was briefly imposed on neighboring conquered states such as Elam and Gutian people, Gutium. Akkad is sometimes regar ...
