Johannes Trithemius (1462-1516)

• Catalog of necromantic texts from Antipalus Maleficiorum.
  
  
• The Seven Secondary Intelligences (De septem secundeis)

  Master cryptographer and magician, Trithemius was the mentor of Henrich Cornelius Agrippa. Here he presents a concise history of the world, and how it has been shaped by angelic agents. (English translation)

• Steganographia (Secret Writing) Book 1 Book 2 Book 3

  This is Trithemius' most notorious work. On the surface it is a system of angel magic, but within is a highly sophisticated system of cryptography. It claims to contain a synthesis of the science of knowledge, the art of memory, magic, an accelerated language learning system, and a method of sending messages without symbols or messenger. In private circulation, the Steganographia brought such a reaction of fear that he decided it should never be published. He reportedly destroyed the more extreme portions (presumably instructions for prophecy/divination) but it continued to circulate in manuscript form and was eventually published posthumously in 1606.
