The chronology of ancient Egypt and Babylonia is wrong to a dramatic degree, with some major historical events mis-dated almost two thousand years before they actually occurred, according historian Emmet Sweeney. Sweeney argues that the pyramids, for instance, were not built around 2350 BC, as is currently thought, but only around 800 BC. The dating of ancient history is often much more tenuous than most people realize and is not based on science but on venerated literary tradition. This chronology had already been established by the third century BC, when Jewish historians utilizing the "History of Egypt" by the Hellenistic author Manetho sought to link Egypt's history with that of the Bible. The pyramids were partly constructed of hard granite and display in their design a knowledge of Pythagorean geometry, yet in 2350 BC the Egyptians only had copper and flint tools and such principles of mathematics had yet to be formulated. This mystery has led to all sorts of weird and wonderful theorizing - not least the idea that the pyramids were built by aliens or Atlanteans. But revise the date of the pyramids' construction to around 800 BC, when steel tools were available and more sophisticated principles of geometry were widely understood, and the mystery is solved. Sweeney's conclusions are revolutionary but they are in line with a growing number of academics who acknowledge that there may be something radically wrong with ancient chronology. Wolfgang Helck, Germany's foremost Egyptologist, recently admitted that work on chronology "has clearly arrived at a crisis." The Pyramid Age is part of an originally-researched reconstruction, "Ages in Alignment", which begins with the start of literate civilization and ends with the conquest of Alexander. The current volume will be followed by Ramessides, Medes and the Persians. Inspired by Velikovsky's 1952 series "Ages in Chaos," this series seeks to complete the work which Velikovsky commenced, identifying the problems he could not solve and bringing forward a great body of evidence which supports his claims, including the identification of Hatshepsut with the Queen of Sheba. For decades now scholars have attempted to solve the enigma. Yet the answer was stunningly simple, and in front of us all the time. * Emmet Sweeney holds a Masters Degree in Early Modern History from the University of Ulster, Northern Ireland, and is currently a lecturer at West University, Timisoara, Romania.
