The Osireion at Abydos and claims of extreme antiquity

Record summary

The Osireion is a subterranean or partly enclosed monument at Abydos associated with Osiris and physically linked to the temple complex of Seti I. Its massive stonework, unusual layout, and apparent weathering have led popular authors to argue that it predates dynastic Egypt by thousands of years and was built by a lost civilization. Egyptological interpretations generally place its construction in the New Kingdom, while recognizing later alterations and uncertainties about its exact ritual history. The site is valuable for comparing architectural appearance with stratigraphic and inscriptional evidence.
