The Mysteries: Papers from the Eranos Yearbooks, edited by Joseph Campbell, the 1990 fifth paperback printing of Bollingen Series XXX Vol 2 from Princeton University Press, is part of the collection at the Reading Room.

“Since 1933, the Eranos Conferences have been held at Ascona in southern Switzerland. Distinguished scholars from Europe, Asia, and America have been invited to a ‘shared feast’ (eranos) and have lectured on themes chosen by the Director of Eranos, the late Olga Froebe-Kapteyn. The lectures originally appeared in the Eranos-Jahrbücher (Zurich) and selections translated into English have been published in Papers from the Eranos Yearbooks, of which this is the second volume. Thirteen scholars—including C. G. Jung, C. Kerényi, Walter F. Otto, and Hugo Rahner—are represented in this collection, which is drawn from the years 1936, 1939m 1940–41, 1942, and 1944. The volume is edited by Joseph Campbell and translated by Ralph Manheim and R.F.C. Hull.” — back cover
