A collection of Greek writings attributed to Hermes Trismegistos, dating from some time before the close of the second century AD, Corpus Hermeticum forms the core of the Hermetic tradition, and was one of the main influences on and motivational factors for the Renaissance. This OMTO edition is based upon the classic translation by GRS Mead, lightly updated into more contemporary English to make the writings more accessible, however, with every effort made to leave Mead's masterful grammatical style intact. This is one of the world's greatest religio-philosophical and spiritual texts. It speaks directly to the human spirit and is the antithesis of an exoteric work, but rather one that aims to promote personal Gnosis. For these reasons, this edition resists the temptation to impose further interpretation or commentary upon the reader.
