The Book of Most Powerful Spirits

or a Compendium of Unnatural Black Magic

Containing the Summonings and Names of various Spirits.

In magical experiments, the first and greatest necessary requirement is always the construction of a circle, because without it, no one would be protected and safe from evil spirits, seeing as they are always enemies of the human race. Therefore, let the Master make a circle from virgin parchment parchment made from the skin of an animal that has not mated nine feet in width, and upon which the names must be written with the blood of a white dove, as is seen in the figure.
