At first glance you might think this is the Titan Prometheus, but instead it is someone else who was condemned to have his liver gnawed on by a vulture: the giant Tityus, who raped the goddess Latona. The children of Latona, Apollo and Artemis, killed Tityus, and then in the afterlife he was condemned to have his liver perpetually eaten away by not one but two vultures; you can find out more at Wikipedia, and you can learn more about Titan's painting at the Web Gallery of Art.
