History of Egypt
In Manetho's "Aegyptiaca" (History of Egypt), a pharaoh called "Sesostris" occupied the same position as the known pharaoh Senusret III of the Twelfth Dynasty, and his name is now usually viewed as a corruption of Senusret/Senwosret/Senwosri. In fact, he is commonly believed to be based on Senusret III, with the possible addition of memories of other namesake pharaohs of the same dynasty, as well as Seti I and Ramesses II of the much later Nineteenth Dynasty.
