“The comparative study of the mythologies of the world compels us to view the cultural history of mankind as a unit; for we find that such themes as the fire-theft, deluge, land of the dead, virgin birth, and resurrected hero have a worldwide distribution – appearing everywhere in new combinations while remaining, like the elements of a kaleidoscope, only a few and always the same”.

Joseph Campbell, The Masks of God: Primitive Mythology
