The Hermetic tradition represents a non-Christian lineage of Hellenistic Gnosticism. The central texts of the tradition, the Corpus Hermeticum were lost to the West in classical times. Their rediscovery and translation during the late-fifteenth century by the Renaissance court of Cosimo de Medici, provided a seminal force in the development of Renaissance thought and culture. The complete Corpus Hermeticum is comprised of 18 tracts. Only the first and primary thirteen of these are presently contained in our library. The texts presented here are taken from the very fine translation of G.R.S. Mead, Thrice Great Hermes: Studies in Hellenistic Theosophy and Gnosis, Volume II (London: Theosophical Publishing Society, 1906).
