Corpus Hermeticorum

in Latin, author unknown, ca. 100 A.D.

This thick tome collects several earlier texts which came to form the nucleus of the Western Hermetic tradition. The influences of elemental forces on the material world are revealed, along with endless tables and charts of hermetic correspondences. The extensive formulae contained within are the backbone of medieval magic. This book is fabulously rare, and the copy at the Miskatonic's Library was part of the Orne Bequest. (Johnson, Sam, and Sandy Antunes. "Miskatonic University: A Handbook to the Pride of Arkham."
