An ancient Latin text, the Ad Herennium, lays down instructions for building effective Memory Systems. These instructions just happen to mirror one of the central images of Christianity as found in the Gospels. Were the Gospels constructed to act as a type of literary memory system? Could it be that the authors were actually adepts at the Art of Memory? Perhaps the tri-fold nature of the Synoptic Gospels is not a historical accident, but is actually a method of encrypting the data contained within the miraculous tales of Jesus the Wonder Worker. More importantly, perhaps this correspondence is a signifier to anyone familiar with the Art of Memory, that here is something screaming for attention, begging to be decrypted, promising, knock, and the door will be opened. The Gnostic Notebook is an examination of hidden layers of meaning uncovered within various classic and ancient texts including the Grimm Brothers' fairy tales and the Gospels. The meanings are decrypted using a variety of steganographic and cryptographic techniques. These hidden readings are not the usual esoteric or Freudian interpretations, rather they seem to reveal actual, undeniable information encoded into the texts ages ago.
