Pyramid Of Chephren
The pyramid of Khafre or of Chephren is the middle of the three Ancient Egyptian Pyramids of Giza, the second tallest and second largest of the group. It is the only pyramid out of the three that still has cladding at the top. It is the tomb of the Fourth-Dynasty Pharaoh Khafre (Chefren), who ruled . Size The pyramid has a base length of 215.5 m (706 ft) or 411 cubits and rises up to a height of or 274 cubits. It is made of limestone blocks weighing more than 2 tons each. The slope of the pyramid rises at a 53° 08' angle, steeper than its neighbor, the pyramid of Khufu, which has an angle of 51° 50' 24". Khafre's pyramid sits on bedrock 10 m (33 ft) higher than Khufu's pyramid, which makes it appear to be taller. Construction Like the Great Pyramid, a rock outcropping was used in the core. Due to the slope of the plateau, the northwest corner was cut 10 m (33 ft) out of the rock subsoil, and the southeast corner was bui ...

Pyramid Of Khafre And Sphinx, Giza, Greater Cairo, Egypt
A pyramid () is a Nonbuilding structure, structure whose visible surfaces are triangular in broad outline and converge toward the top, making the appearance roughly a Pyramid (geometry), 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 (geometry), 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 Civilization, 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 List of largest buildings in the world, largest structures on Earth ...

Limestone
Limestone is a type of carbonate rock, carbonate sedimentary rock which is the main source of the material Lime (material), lime. It is composed mostly of the minerals calcite and aragonite, which are different Polymorphism (materials science), crystal forms of calcium carbonate . Limestone forms when these minerals Precipitation (chemistry), 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 (rock), dolomite, a closely related rock, which contains a high percentage of the mineral Dolomite (mine ...

Auguste Mariette
François Auguste Ferdinand Mariette (11 February 182118 January 1881) was a French scholar, archaeologist and Egyptologist, and the founder of the Egyptian Department of Antiquities, the forerunner of the Supreme Council of Antiquities. Early career Auguste Mariette was born in Boulogne-sur-Mer, where his father was town clerk. Educated at the Boulogne municipal college, where he distinguished himself and showed much artistic talent, he went to England in 1839 when eighteen as professor of French and drawing at a boys' school at Stratford-upon-Avon. In 1840 he became pattern-designer to a ribbon manufacturer in Coventry, but he returned the same year to Boulogne, and in 1841 took a degree at the University of Douai. Mariette proved to be a talented draftsman and designer, and he supplemented his salary as a teacher at Douai by giving private lessons and writing on historical and archaeological subjects for local periodicals. Meanwhile, his cousin Nestor L'Hôte, the friend ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
John Shae Perring
John Shae Perring (24 January 1813, Boston, Lincolnshire – 16 January 1869, Manchester) was a British engineer, anthropologist and Egyptologist, most notable for his work excavating and documenting Egyptian pyramids. Career In 1837 Perring and British archaeologist Richard William Howard Vyse began excavating at Giza; they were later joined by Giovanni Battista Caviglia. They used gunpowder to force their way into several monuments and then to reach hidden chambers within them, such as the burial chamber of the pyramid of Menkaure, documenting them as they went. When Caviglia left the team to work independently, Perring became Vyse's assistant and when Vyse himself left for England in 1837 Perring continued the excavation with Vyse's financial support. As part of his work, Perring created several maps, plans and cross-sections of the pyramids at Abu Roasch, Gizeh, Abusir, Saqqara and Dahshur. He was the first to explore the interior of the Pyramid of Userkaf at Saqqara in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sarcophagus
A sarcophagus (: sarcophagi or sarcophaguses) is a coffin, most commonly carved in stone, and usually displayed above ground, though it may also be buried. The word ''sarcophagus'' comes from the Greek language, Greek wikt:σάρξ, σάρξ ' meaning "flesh", and wikt:φαγεῖν, φαγεῖν ' meaning "to eat"; hence ''sarcophagus'' means "flesh-eating", from the phrase ''lithos sarkophagos'' (wikt:λίθος, λίθος wikt:σαρκοφάγος, σαρκοφάγος), "flesh-eating stone". The word also came to refer to a particular kind of limestone that was thought to rapidly facilitate the corpse decomposition, decomposition of the flesh of corpses contained within it due to the chemical properties of the limestone itself. History of the sarcophagus Sarcophagi were most often designed to remain above ground. The earliest stone sarcophagi were used by Pharaoh, Egyptian pharaohs of the 3rd dynasty, which reigned from about 2686 to 2613 BC. The Hagia Triada sarcoph ...

Giovanni Belzoni
Giovanni Battista Belzoni (; 5 November 1778 – 3 December 1823), sometimes known as The Great Belzoni, was a prolific Italian explorer and pioneer archaeologist of Egyptian antiquities. He is known for his removal to England of the seven-tonne bust of Ramesses II, the clearing of sand from the entrance of the great temple at Abu Simbel, the discovery and documentation of the tomb of Seti I (still sometimes known as "Belzoni's Tomb"), including the sarcophagus of Seti I, and the first to penetrate into the Pyramid of Khafre, the second pyramid of the Giza complex. Early life Belzoni was born in Padua. His father was a barber who sired fourteen children. His family was from Rome and when Belzoni was 16 he went to work there, saying that he studied hydraulics. He intended on taking monastic vows, but in 1798 the occupation of the city by French troops drove him from Rome and changed his proposed career. In 1800 he moved to the Batavian Republic (now Netherlands) where he ear ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Astronomy
Astronomy is a natural science that studies celestial objects and the phenomena that occur in the cosmos. It uses mathematics, physics, and chemistry in order to explain their origin and their overall evolution. Objects of interest include planets, natural satellite, moons, stars, nebulae, galaxy, galaxies, meteoroids, asteroids, and comets. Relevant phenomena include supernova explosions, gamma ray bursts, quasars, blazars, pulsars, and cosmic microwave background radiation. More generally, astronomy studies everything that originates beyond atmosphere of Earth, Earth's atmosphere. Cosmology is a branch of astronomy that studies the universe as a whole. Astronomy is one of the oldest natural sciences. The early civilizations in recorded history made methodical observations of the night sky. These include the Egyptian astronomy, Egyptians, Babylonian astronomy, Babylonians, Greek astronomy, Greeks, Indian astronomy, Indians, Chinese astronomy, Chinese, Maya civilization, M ...

John Greaves
John Greaves (1602 – 8 October 1652) was an English mathematician, astronomer and antiquarian. Education Educated at Balliol College, Oxford, he was elected a Fellow of Merton College in 1624. He studied Persian and Arabic, acquired a number of old books and manuscripts for archbishop William Laud (some still in Merton College Library), and wrote a treatise (in Latin) on the Persian language. He travelled in Italy and the Levant from 1636 to 1640 and made a survey of the Great Pyramid of Giza. He was Gresham Professor of Geometry at Gresham College, London, and Savilian professor of astronomy at Oxford University, and collected astrolabes and astronomical measuring devices (now in the Museum of the History of Science, Oxford). He was particularly interested in the study of weights and measures, and wrote a treatise on the Roman foot and denarius, and was a keen numismatist. In 1645 he attempted a reform of the Julian calendar, which was not adopted. During the Engli ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Graffito (archaeology)
A graffito (plural "graffiti"), in an archaeological context, is a deliberate mark made by scratching or engraving on a large surface such as a wall. The marks may form an image or writing. The term is not usually used for the engraved decoration on small objects such as bones, which make up a large part of the art of the Upper Paleolithic, but might be used for the engraved images, usually of animals, that are commonly found in caves, though much less well known than the cave paintings of the same period; often the two are found in the same caves. In archaeology, the term may or may not include the more common modern sense of an "unauthorized" addition to a building or monument. Sgraffito, a decorative technique of partially scratching off a top layer of plaster or some other material to reveal a differently colored material beneath, is also sometimes known as "graffito". Categories The basic categories of graffiti in archaeology are: *Written graffiti, or informal inscr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arabic Language
Arabic (, , or , ) is a Central Semitic languages, Central Semitic language of the Afroasiatic languages, Afroasiatic language family spoken primarily in the Arab world. The International Organization for Standardization (ISO) assigns language codes to 32 varieties of Arabic, including its standard form of Literary Arabic, known as Modern Standard Arabic, which is derived from Classical Arabic. This distinction exists primarily among Western linguists; Arabic speakers themselves generally do not distinguish between Modern Standard Arabic and Classical Arabic, but rather refer to both as ( "the eloquent Arabic") or simply ' (). Arabic is the List of languages by the number of countries in which they are recognized as an official language, third most widespread official language after English and French, one of six official languages of the United Nations, and the Sacred language, liturgical language of Islam.

Burial Chamber
A chamber tomb is a tomb for burial used in many different cultures. In the case of individual burials, the chamber is thought to signify a higher status for the interred than a simple grave. Built from rock or sometimes wood, the chambers could also serve as places for storage of the dead from one family or social group and were often used over long periods for multiple burials. Most chamber tombs were constructed from large stones or megaliths and covered by cairns, barrows or earth. Some chamber tombs are rock-cut monuments or wooden-chambered tombs covered with earth barrows. Grave goods are a common characteristic of chamber tomb burials. In Neolithic and Bronze Age Europe, stone-built examples of these burials are known by the generic term of megalithic tombs. Chamber tombs are often distinguished by the layout of their chambers and entrances or the shape and material of the structure that covered them, either an earth barrow or stone cairn.
