As the shadows of the Third Reich gathered in the late 1930s, a small coterie of scholars engaged in the esoteric began gathering in Ascona, Switzerland, in the hopes of generating a counterforce, a mystical response to history's dark turn that would light a new path. By drawing together luminaries such as Carl Jung, Gerschom Scholem, Heinrich Zimmer, Joseph Campbell, Henri Corbin and D.T. Suzuki, Eranos became mysticism's premier midcentury space. This lecture draws upon the instructor’s archival research into Joseph Campbell's role as the editor of The Eranos Yearbooks, along with primary and secondary sources to suggest that the legacy of Eranos remains a provocative and rich text for contemplating mysticism's relationship with history.
