Diodorus Siculus
He (Osiris) also took Pan along on his campaign, who is held in special honour by the Egyptians; for the inhabitants of the land have not only set up statues of him at every temple but have also named a city after him in the Thebaid, called by the natives Chemmo, which when translated means City of Pan. — 1.18
Osiris has been given the name Sarapis by some, Dionysos by others, Pluto by others, Ammon by others, Zeus by some, and many have considered Pan to be the same God; and some say that Sarapis is the God whom the Greeks call Pluto. — 1.25
