 The city was also at one point referred to as Ankh-Tawy (meaning "Life of the Two Lands"), stressing the strategic position of the city between Upper and Lower Egypt.This name appears to date from the Middle Kingdom (c. 2055–1640 BCE), and is frequently found in ancient Egyptian texts.Some scholars maintain that this name was actually that of the western district of the city that lay between the great Temple of Ptah and the necropolis at Saqqara, an area that contained a sacred tree.
