The book brings together the four works attributed to Hermes Trismegisto, fundamental texts of the Hermetic philosophy. Written in Greek, and surely belonging to some Alexandrian author, they include: Poimandres, where the keys to the creation of the world are exposed; the Discourse on Initiation or Asclepius, where Hermes lectures Asclepius, Tat, and Ammon, gathered in a temple, and which provides essential ideas for sacred initiation in hermetic circles; in addition to The Virtue of the World and the Dialogues from Hermes to Amun.
