Osirion

The Osireion is believed to be the cenotaph of Seti I, located to the rear of the Temple of Seti I at Abydos, Egypt [1]. The Osireion is part of the Temple of Seti I's complex [1]. Most of its structure would have been subterranean [1]. The Osireion was rediscovered by archaeologists Flinders Petrie and Margaret Murray, who were excavating the site in 1902–1903 [1]. The Egypt Exploration Society (EES) excavations uncovered an ancient mark; “Menmaatre [Seti I] is Beneficial to Osiris” [1]. The EES came to the conclusion that it was built during the reign of Seti I, as detailed in its report published in 1933 [1].
