Greek name for the Egyptian city of Iunu, capital of the 13th LowerEgyptian nome in the suburbs of present-day Cairo. Its main temple was dedicated to the creator god Atum, who was identified with the sun god Re, elevated to the chief god in Egypt beginning during Dynasty 5. Very little remains of the original city and temple apart from an obeliskof Senusret I. Many of the monuments appear to have been transported to decorate Alexandria during the Ptolemaic Periodand Roman Period. Excavations were carried out by an Italian expedition in 1903, Flinders Petrie from 1911–1912, the University of Cairo from 1976–1981, and Egyptian inspectors since 1988.
