Definition: Pepy I, son of Teti (r. 2374-2354 B.C.) and Queen Ipout, was a long ruling pharaoh (r. c.2354-2310 B.C.) of the 6th dynasty in ancient Egypt. Manetho says he ruled for 53 years. His rule is described as the high point of the Old Kingdom for the architectural and artistic accomplishments. He also sent out military and copper mining expeditions.
Pepy I's funerary complex is at Saqqara. The name of his pyramid was Men-nefer-Pepy ("Pepy is stable and perfect"). Men-nefer is the name given to the nearby capital, but it was called Memphis by the Greeks.
