A category of popular "Late Antique" literature said to contain secret wisdom, and generally attributed to "Hermes Trismegistus", "Thrice-great Hermes": Hermeticas consist of collections of several Greek texts from the second and third centuries which were survivors from other extensive works of literature and that were compiled into a "Corpus Hermeticum" by Italian scholars during the Renaissance.

Additional Hermeticas existed in Syriac, Arabic, Armenian, Coptic, and other languages.
