Unaussprechlichen Kulten

in German, written by Friedrich Wilhelm von Junzt, 1838

Von Junzt spent close to a decade travelling the globe, studying various secret cults and dark religions. This massive, fabulously rare original edition is over a thousand pages long, and details fourteen different cults, one for each chapter. Also known as the Black Book. The version contained in the University Library was donated as part of the Tuttle Bequest. (Johnson, Sam, and Sandy Antunes. "Miskatonic University: A Handbook to the Pride of Arkham."
