Depicting Nike, the goddess of victory, mounted in her chariot, a biga with two horses in the foreground with galloping legs, the goddess with wings outstretched, wearing a crown in her hair, holding a wreath in her right hand, a leafy spray in her left, surrounded by a border, 16¾in (42.5cm) x 14in (35.5cm), mounted
The style of depicting the horses appears to be after a Greek prototype of the late Classical to early Hellenistic periods. Cf. the scene of Hades and Persephone in the underworld on the back of the marble throne in the Macedonian tomb of Eurydice, Heracles to Alexander the Great, Exhibition Catalogue, Ashmolean Museum, Oxford, 2011, p. 102, fig. 92.
