The Masks of God is the summation of Joseph Campbell's lifelong study of the origins and function of myth. In this volume, Occidental Mythology, Campbell examines the themes that underlie the art, worship and literature of the Western world. Occidental Mythology traces European consciousness from the Levantine earth-goddesses of the Bronze Age and the subsequent tribal invasions that shaped Judaic and Greek myth before examining the influence of Persia, Rome, Islam and Christian Europe on ancient beliefs. The Masks of God traces mankind's history as a search for meaning through ideas, themes and quests of culture and religion.
