Volute krater (wine-mixing vessel), about 570 - 560 B.C.

Procession of gods. The chariot of Zeus and Hera. Their pole horses have topknots and hold their heads up high; Zeus holds his thunderbolt, whip and reins, and wears a long white peplos and mantle. Hera, beside him, wears a figured peplos and mantle, and holds her mantle with her left hand. Their chariot is accompanied by two Muses: here, Kalliope, full frontal and playing the Pan-pipes, and Urania, her hair tied in a bun, wearing a figured peplos and holding her left hand in the air.
