The Latin code of gematria is the key that unlocks the meaning of some of Freemasonry’s greatest secrets. It does this both in conjunction with the codes for Hebrew and classical Greek and more especially by virtue of the fact that it also provides the means to procure the cabalistic coding of English. The three cabalistic codes are all recorded in one of the main sourcebooks for the esoteric teachings of high degree Freemasonry – Agrippa’s Three Books of Occult Philosophy (1531).
