Jason was an ancient Greek mythological hero and leader of the Argonauts, whose quest for the Golden Fleece is a prominent tale in Greek literature. He was the son of Aeson, the rightful king of Iolcos, and the great-grandson of the messenger god Hermes through his mother's lineage.

His adventures are depicted in numerous classical literary works, such as the epic poem Argonautica by Apollonius of Rhodes and the tragedy Medea. Jason's legacy extends to modern interpretations and adaptations of his myth, including appearances in films like the 1963 Jason and the Argonauts and the 2000 TV miniseries of the same name.
