These are spiritual texts of unknown origin written down in the second and third centuries AD. They contain religious and philosophical teachings ascribed to Hermes Trismegistus ('Thrice Great Hermes'), whom the Greeks identified with Thoth, the ancient Egyptian god of wisdom. It is the conventional scholarly view that the ideas here are no older than the epoch in which the texts were written down. However, my own readings have convinced me that this cannot possibly be so and that the Hermetica pursue precisely the same quest for immortality through knowledge, in the same way as The Ancient Egyptian Pyramid Texts. There is a clear sense of human life as a precious opportunity for the soul to learn, grow and develop, to confront moral and intellectual challenges and to make choices that will have a heavy bearing on our immortal destiny.
