I am now enrolling studients for a new class, The Other Trithemian Art: Secret Codes and Ciphers of the Magicians. This is a four week course that will teach you how to use codes and ciphers to enrich your magical practice. For a full description, read the class page.
Since this class will involve extra one-on-one teaching to help with the math and difficult concepts, enrollment is very limited! You will want to sign up early to reserve your spot. Also, until January 31st, you can use code EARLYWEB to get 30% off!
