This golden fleece, and Jason’s quest for it, seem to portray the theme of the slaying of the Old Father, and the quest for individual spiritual identity, which I feel to be at the core of the drama of Aries the Ram.
Greene reads Jason’s quest for the Golden Fleece as an archetypal enactment of individuation — the struggle to recover the inner father-spirit and assert sovereign selfhood — situated at the mythic core of the Aries archetype.
