The Mask of Circe
Jay Seward is a psychiatrist who allows himself to be a guinea pig for a technique for uncovering buried memories. The experiment goes too deep and uncovers things that should have stayed buried. Jay Seward fings himself answering a call he's never been aware of, and he becomes Jason (as in, Jason and the Argonauts). He believes he's been taken backwards in time. In this new place and time, two groups want him. The priests of Apollo want him to lead... The Proud Robot
