The Hero with a Thousand Faces
Campbell's 1949 study of comparative mythology, first published in the Bollingen Series. It argues that hero stories from many cultures, including those of Osiris, the Buddha and Moses, share one underlying pattern of departure, initiation and return, which he called the monomyth.
