The event of the release of Prometheus from captivity was frequently revisited on Attic and Etruscan vases between the sixth and fifth centuries BC. In the depiction on display at the Museum of Karlsruhe and in Berlin, the depiction is that of Prometheus confronted by a menacing large bird (assumed to be the eagle) with Hercules approaching from behind shooting his arrows at it. In the fourth century this imagery was modified to depicting Prometheus bound in a cruciform manner, possibly reflecting an Aeschylus-inspired manner of influence, again with an eagle and with Hercules approaching from the side.
