In 1943, Jung held a seminar at Eranos for a limited number of students dedicated to ‘solar myths’, which were exemplified specifically in the cartographic art of Opicinus de Canistris (c. ). This seminar has stayed out of print until a few years ago. Notes taken during the seminar by one of Jung's students, Alwine von Keller , were discovered in the Eranos archives and published. Now, for the first time ever, the notes of another of his students, Rivkah Schärf Kluger, taken during the same seminar, are being published. This second series of notes are more extensive. They complete the first series by adding many features and so allow us to put together a more complete picture of Jung's seminar. James Hillman, who received these notes from William McGuire in 1976, firmly believed that they were important enough to be published. Now, seventy years after this seminar, thanks to the support of the Stiftung der Werke von C. G. Jung, the Eranos Foundation and the Journal of Analytical Psychology, these notes are finally being published.
