Fragment of a kylix joined to 53.11.4. The subject of the decoration is elucidated in a poem by Bacchylides, active in the fifth century B.C. On the interior and one side of the exterior, Theseus, who is bound for Crete to kill the Minotaur, takes leave of his father and stepmother, Poseidon and Amphitrite. On the other side, the victorious Theseus is welcomed back to Athens by Athena.
