The Cult
No sanctuary, altar, priesthood, or festival of Kérberos is attested anywhere in the surviving record: he is the rare major figure of Greek myth who was never the recipient of cult, only its guardian-symbol. What the sources give instead is the ritual complex gathered around him. The honey-cake the Sibyl feeds him in the Aeneid reflects real Roman practice: at the Feralia, the closing day of the Parentalia in February, Ovid describes an old woman baking honeyed liba for the Manes, and honeyed sops were a standing grave-offering — the passage-rite made edible. His threshold was localized in living sanctuaries of the dead: the cave at Cape Tainaron with its temple of Poseidon (Pausanias 3.25.5), the oracle of the dead at Ephyra on the Acheron in Thesprotia (Pausanias 1.17.5), and the sanctuary of Clymenos — a name of Hades — at Hermione (Pausanias 2.35). On Roman cinerary urns and sarcophagi he stands at the tomb's door doing the job no priest could: keeping what is inside, in.
