The esoteric implements of the medieval necromancer included magic circles, conjurations, sacrifices, swords, and prayer; magical alphabets were also highly significant. Circles were traced on the ground, often accompanied by various mystical symbols drawn from a mixture of Christian and occult ideas. At the opportune time and location, sacrifices and animal offerings were often provided to propitiate ethereal beings.
The most important medieval writings on the occult were by the Benedictine abbot Johannes Trithemius (1462-1516), and his pupil, Heinrich Cornelius Aggripa (1486-1535). The latter’s Three Books About Occult Philosophy (1531-33) included coded formulae for alchemy, Kabbalism, and the Theban alphabet, a table for communicating with the spirit world.— Excerpted from The Book of Codes, page 57.
