Yog-Sothoth and Cthulhu.

_Unaussprechlichen Kulten_ published in Dusseldorf. Written
by Friedrich von Junzt (1795-1840) [read _Necronomicon_ in Greek
translation]. Von Junzt dies six months after returning from trip
to Mongolia while working on second book. Less than a dozen copies
exist of this edition. ["Von Junzt relates many stories of the
survivals of cults worshipping pre-human entities or prehistoric
gods, such as Ghatanothoa, Bran, and others. The principle
obscurity of the book is in Von Junzt's use of the term 'keys' --
phrase used many times by him, in various relations, such as
descriptions of the infamous Black Stone in Hungary and the
legendary Temple of the Toad in Honduras."]
Bridewell, London publisher, does a pirated translation of
