Monas Hieroglyphica

The Monas Hieroglyphica (or Hieroglyphic Monad) is an esoteric symbol invented and designed by John Dee, the Elizabethan Magus and Court Astrologer of Elizabeth I of England. It is also the title of the 1564 book in which Dee expounds the meaning of his symbol.

The Hieroglyphic embodies Dee's vision of the unity of the Cosmos and is a composite of various esoteric and astrological symbols. Dee wrote a commentary on it which serves as a primer of its mysteries.
