Traditional Forms and Cosmic Cycles is a wide-ranging collection of articles that delve into traces of ancient, indeed protohistoric, traditions. Although they must remain fragments, as Guénon did not return to many of these themes, it would have been regrettable to leave such fascinating articles buried in old journals, and so this posthumous collection is now offered to Anglophone readers for the first time. The book opens with the key article 'The Doctrine of Cosmic Cycles', followed by two pieces on Atlantis and Hyperborea. Two sections follow, concerned respectively with the Hebrew Tradition and the Egyptian Tradition. The former comprises five articles concerned primarily with the Kabbalah and the Science of Numbers, and the latter includes three articles on Hermes and the Hermetic Tradition. Book reviews are inserted at relevant points.
