Around the body, hoplites (foot soldiers) are mounted on dolphins. This procession of identically dressed foot soldiers seems to advance with military precision. A number of other dolphin-riding hoplites appear on vases of this period. All are accompanied by a flute player, suggesting that this scene illustrates a dramatic chorus, probably from a contemporary play. The six dolphins would have seemed to leap and dive as the psykter, filled with wine, bobbed in ice water inside a large krater. Oltos was an early red-figure painter who specialized in decorating cups and other shapes used in symposia (drinking parties).
