If we look at The Mythic Image within the context of the Campbell oeuvre, it appears as if it should have been the first of his published works, and that his works beginning with The Hero with a Thousand Faces and the Masks of God should find their places as extensive commentaries and footnotes to The Mythic Image.
Noel argues that The Mythic Image is the generative nucleus of Campbell’s entire intellectual project, with all other major works serving as its elaborative apparatus.
