The term particularly applies to the Corpus Hermeticum, Marsilio Ficino's Latin translation in fourteen tracts, of which eight early printed editions appeared before 1500 and a further twenty-two by 1641. This collection, which includes Poimandres and some addresses of Hermes to disciples Tat, Ammon and Asclepius, was said to have originated in the school of Ammonius Saccas and to have passed through the keeping of Michael Psellus: it is preserved in fourteenth century manuscripts. The last three tracts in modern editions were translated independently from another manuscript by Ficino's contemporary Lodovico Lazzarelli (1447–1500) and first printed in 1507. Extensive quotes of similar material are found in classical authors such as Joannes Stobaeus.
