Shallow bowl decorated in metallic black glaze with a prominent central raised boss (omphalos). Decorated in moulded relief with a frieze, around the boss, of four quadrigae, each driven by a Victory and containing Athena, Heracles, Ares and Dionysus. The scene is probably the apotheosis of Herakles. The underside of the boss is reserved.
