Although the Greeks and Romans typically scorned Egyptian animal-headed gods as bizarre and primitive (Anubis was mockingly called "Barker" by the Greeks), Anubis was sometimes associated with Sirius in the heavens and Cerberus and Hades in the underworld.[30] In his dialogues, Plato often has Socrates utter oaths "by the dog" (kai me ton kuna), "by the dog of Egypt", and "by the dog, the god of the Egyptians", both for emphasis and to appeal to Anubis as an arbiter of truth in the underworld.[31]
