Perhaps the most famous treatment of the myth can be found in the Greek tragedy Prometheus Bound – traditionally attributed to the 5th-century BC Greek tragedian Aeschylus. At the center of the drama are the results of Prometheus' theft of fire and his current punishment by Zeus; the playwright's dependence on the Hesiodic source material is clear, though Prometheus Bound also includes a number of changes to the received tradition. Before his theft of fire, Prometheus played a decisive role in the Titanomachy, securing victory for Zeus and the other Olympians. Zeus's torture of Prometheus thus becomes a particularly harsh betrayal. The scope and character of Prometheus' transgressions against Zeus are also widened. In addition to giving humankind fire, Prometheus claims to have taught them the arts of civilization, such as writing, mathematics, agriculture, medicine, and science. The Titan's greatest benefaction for humankind seems to have been saving them from complete destruction.
