Lake Moeris
Oxyrhynchus lies west of the main course of the Nile on the Bahr Yussef, a branch that terminates in Lake Moeris and the Faiyum oasis. In ancient Egyptian times, there was a city on the site called Per-Medjed, named after the medjed, a species of elephantfish of the Nile worshipped there as the fish that ate the penis of Osiris. It was the capital of the 19th Upper Egyptian Nome.
