Egyptian Pyramid Construction Techniques
Egyptian pyramid construction techniques are the controversial subject of many hypotheses. These techniques seem to have developed over time; later pyramids were not constructed in the same way as earlier ones. Most of the construction hypotheses are based on the belief that huge stones were carved from quarries with copper chisels, and these blocks were then dragged and lifted into position. Disagreements chiefly concern the methods used to move and place the stones. In addition to the many unresolved arguments about the construction techniques, there have been disagreements as to the kind of workforce used. The Greeks, many years after the event, believed that the pyramids must have been built by slave labor. Archaeologists now believe that the Great Pyramid of Giza (at least) was built by tens of thousands of skilled workers who camped near the pyramids and worked for a salary or as a form of tax payment (levy) until the construction was completed, pointing to workers' cemeteri ...

Pyramids Of The Giza Necropolis
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 pyramid ...

Djehutihotep
Djehutihotep ("''Thoth is satisfied''") was an ancient Egyptian nomarch of the fifteenth '' nomos'' of Upper Egypt (''" the Hare"'') during the twelfth dynasty, c. 1900 BC. Biography Djehutihotep lived under the reigns of Amenemhat II, Senusret II, and Senusret III and was one of the most powerful nomarchs of the Middle Kingdom. His tomb—the only one among the necropolis of Deir el-Bersha that wasn't damaged by the explosives used in recent quarrying methods—is well known for the great quality of its decorations, a work carried out by an artist named Amenaankhu. For this reason, it is believed that Djehutihotep died prior to the strict measures reducing the power of the nomarchs that were established by Senusret III. Indeed, as their charge became hereditary at the end of the Old Kingdom, the nomarchs became local rulers effectively, although not nominally, independent of the pharaohs. This situation led to excesses in the exercise of power that worsened steadi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hieronymus Of Rhodes
Hieronymus of Rhodes ( grc, Ἱερώνυμος ὁ Ῥόδιος, Hierṓnymos ho Rhódios, la, Hieronymus Rhodius; – ) was a Peripatetic philosopher, and an opponent of Arcesilaus and Lyco of Troas. Only a few fragments of his works survive, preserved in the quotations of later writers. Life Hieronymus belonged to the Peripatetic school, though Cicero questions his right to the title. He appears to have lived down to the time of Ptolemy II Philadelphus. His philosophical opponents included not only the Academic philosopher Arcesilaus, but also the Peripatetic Lyco of Troas who was hostile towards him. Works Hieronymus is frequently mentioned by Cicero, who tells us that he held the highest good to consist in freedom from pain and trouble, and denied that pleasure was to be sought for its own sake. There are quotations from his writings, and from his letters. Diogenes Laërtius mentions two works: ''On Suspense of Judgement'' and ''Scattered Notes''. It would seem from Cic ...

Thales
Thales of Miletus ( ; grc-gre, Θαλῆς; ) was a Greek mathematician, astronomer, statesman, and pre-Socratic philosopher from Miletus in Ionia, Asia Minor. He was one of the Seven Sages of Greece. Many, most notably Aristotle, regarded him as the first philosopher in the Greek tradition, and he is otherwise historically recognized as the first individual known to have entertained and engaged in scientific philosophy.Frank N. Magill''The Ancient World: Dictionary of World Biography'', Volume 1 Routledge, 2003 He is often referred to as the Father of Science. Thales is recognized for breaking from the use of mythology to explain the world and the universe, instead explaining natural objects and phenomena by offering naturalistic theories and hypotheses. Almost all the other pre-Socratic philosophers followed him in explaining nature as deriving from a unity of everything based on the existence of a single ultimate substance instead of using mythological explanations.

Giza
Giza (; sometimes spelled ''Gizah'' arz, الجيزة ' ) is the second-largest city in Egypt after Cairo and fourth-largest city in Africa after Kinshasa, Lagos and Cairo. It is the capital of Giza Governorate with a total population of 9.2 million as of 2021. It is located on the west bank of the Nile, southwest of central Cairo, and is a part of the Greater Cairo metropolis. Giza lies less than north of Memphis (''Men-nefer''), which was the capital city of the first unified Egyptian state from the days of the first pharaoh, Narmer. Giza is most famous as the location of the Giza Plateau, the site of some of the most impressive ancient monuments in the world, including a complex of ancient Egyptian royal mortuary and sacred structures, including the Great Sphinx, the Great Pyramid of Giza, and a number of other large pyramids and temples. Giza has always been a focal point in Egypt's history due to its location close to Memphis, the ancient pharaonic capital of the Old K ...

Tora, Egypt
Tura ( arz, طرة ' , , ) was the primary quarry for limestone in ancient Egypt. The site, which was known by the ancient Egyptians as ''Troyu'' or ''Royu'', is located about halfway between modern-day Cairo and Helwan. Its ancient Egyptian name was misinterpreted by the ancient Greek geographer Strabo, who thought it meant it was inhabited by Trojans, thus the Hellenistic city was named Troia. The site is located by the modern town of ''Tora'' in the Cairo Governorate. Ancient mining town The limestone from Tura was the finest and whitest of all the Egyptian quarries, so it was used for facing stones for the richest tombs, as well as for the floors and ceilings of mastabas, which were otherwise made of mudbrick. It was used during the Old Kingdom and was the source of the limestone used for the "Rhomboidal Pyramid" or Bent Pyramid of Sneferu, the Great Pyramid of Khufu, the sarcophagi of many Old Kingdom nobles, the pyramids of the Middle Kingdom, and certain temples ...

Limestone
Limestone ( calcium carbonate ) is a type of carbonate sedimentary rock which is the main source of the material lime. It is composed mostly of the minerals calcite and aragonite, which are different crystal forms of . Limestone forms when these minerals 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, a closely related rock, which contains a high percentage of the mineral dolomite, . ''Magnesian limestone'' is an obsolete and poorly-defined term used variously for dolomite, for limes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wadi Al-Jarf
Wadi al-Jarf ( ar, وادي الجرف) is the present name for an area on the Red Sea coast of Egypt, south of Suez, that is the site of the oldest known artificial harbour in the world, developed about 4500 years ago. It is located at the mouth of the Wadi Araba, a major communication corridor between the Nile Valley and the Red Sea, crossing the Eastern Desert. The site is across the Gulf of Suez from the small Sinai fortress of Tell Ras Budran. A somewhat similar ancient port is at Ain Sukhna, a little north of Wadi al-Jarf. The site was first discovered by J. G. Wilkinson in 1832. It was rediscovered by a French team in the 1950s, who named it Rod el-Khawaga. Archeological work was quickly abandoned when the Suez Crisis broke out in 1956. A joint French–Egyptian team resumed excavation in 2011. The harbor at the site dates to the Fourth Dynasty of Egypt, approximately 4,500 years ago. Also discovered at the site were more than 100 anchors, the first Old Kingdom anchors f ...

The Diary Of Merer
The Diary of Merer (also known as ''Papyrus Jarf'') is the name for papyrus logbooks written over 4,500 years ago by Merer, a middle ranking official with the title ''inspector'' (''sHD''). They are the oldest known papyri with text, dating to the 27th year of the reign of pharaoh Khufu during the 4th dynasty. The text, written with ( hieratic) hieroglyphs, mostly consists of lists of the daily activities of Merer and his crew. The most well preserved sections (''Papyrus Jarf A and B'') document the transportation of white limestone blocks from the Tura quarries to Giza by boat. Buried in front of man-made-caves that served to store the boats at Wadi al-Jarf on the Red Sea coast, the papyri were found and excavated in 2013 by a French mission under the direction of archaeologists Pierre Tallet of Paris-Sorbonne University and Gregory Marouard. The Egyptian archaeologist Zahi Hawass describes the Diary of Merer as "the greatest discovery in Egypt in the 21st century." Parts of ...

Dolerite
Diabase (), also called dolerite () or microgabbro, is a mafic, holocrystalline, subvolcanic rock equivalent to volcanic basalt or plutonic gabbro. Diabase dikes and sills are typically shallow intrusive bodies and often exhibit fine-grained to aphanitic chilled margins which may contain tachylite (dark mafic glass). ''Diabase'' is the preferred name in North America, while ''dolerite'' is the preferred name in the rest of the English-speaking world, where sometimes the name ''diabase'' refers to altered dolerites and basalts. Some geologists prefer to avoid confusion by using the name ''microgabbro''. The name ''diabase'' comes from the French ', and ultimately from the Greek - meaning "act of crossing over, transition". Petrography Diabase normally has a fine but visible texture of euhedral lath-shaped plagioclase crystals (62%) set in a finer matrix of clinopyroxene, typically augite (20–29%), with minor olivine (3% up to 12% in olivine diabase), magnetite (2%), and ...
