Though all these early Attic vases are fragmentary, the many common features in their depictions of the Gigantomachy suggest that a common model or template was used as a prototype, possibly Athena's "peplos". These vases depict large battles, including most of the Olympians, and contain a central group which appears to consist of Zeus, Heracles, Athena, and sometimes Gaia. Zeus, Heracles and Athena are attacking Giants to the right. Zeus mounts a chariot brandishing his thunderbolt in his right hand, Heracles, in the chariot, bends forward with drawn bow and left foot on the chariot pole, Athena, beside the chariot, strides forward toward one or two Giants, and the four chariot horses trample a fallen Giant. When present, Gaia is shielded behind Herakles, apparently pleading with Zeus to spare her children.
