Map of Egypt
Oxyrhynchus, five days journey by road south of Memphis, is marked with a red arrow: at the deserts edge, and roughly ten miles from the Nile, on the branch of the Nile called Bahr Yussuf. The ancient citys administrative district lay largely to the north. Its nearest neighbour was Cynopolis, City of Dogs, named like Oxyrhynchus for its sacred animal.
Writing under the Empire, Plutarch (On Isis and Osiris 380B-C) reports that when the Cynopolitans started catching and eating the sacred Oxyrhynchus fish, the Oxyrhynchites retaliated by eating dog: the two cities went to war, and it took Roman punitive intervention to subdue them. However implausible this may sound, he insists it happened in our own time (kath' hemas).
