A fine set of the first four volumes (of six) with contributions by many of the greatest names in the field in the 20th century including Jung, Eliade, Kerenyi, Buber, Bernoulli, Neumann, Read, Schrodinger, Wili, etc. "Eranos is an intellectual discussion group dedicated to humanistic and religious studies, as well as to the natural sciences which has met annually in Moscia (Lago Maggiore), the Collegio Papio and on the Monte Verità in Ascona Switzerland since 1933... The name is derived from the Ancient Greek word meaning "a banquet to which the guests bring contributions of food, a no-host dinner." The circle at Moscia was founded by Olga Froebe-Kapteyn in 1933, and these conferences have been held annually on the grounds of her estate (on the shores of Lago Maggiore near Ascona in Switzerland) ever since. For over seventy years this event has served as a point of contact for thinkers from disparate fields of knowledge ranging from depth psychology and comparative religion to history, literary criticism and folklore, and provides a setting and a congenial group within which to discuss all things spiritual."
