unique semiotic approach to The Ancient Egyptian Book of Thoth. This ancient book of sacred wisdom is a dialogue between a spiritual master, perhaps the god Thoth himself, and a student. The text was originally written in Demotic and dates to the Graeco-Roman Period. In the dialogue the master teaches the student secret sacred knowledge using the metaphors and symbols associated with writing. In Ancient Egypt the sacred art of writing was kept hidden in the House of Life, a sanctum sanctorum within the temple scriptorium where the priests wrote their books. The Book of Thoth is maybe the most mystical text of Late Period Egyptian thought. It is therefore of importance to all those interested in Graeco-Roman Period intellectual history and the history of western esotericism. This semiotic approach to the Book of Thoth is especially interesting for students of the Hermetica, the texts written by the Egyptian sage Hermes Trismegistus. The goal of this book is to unlock the wisdom encrypted with metaphors and allegories hidden within this Ancient Egyptian composition.
