The Mercurius Press has recently released Liber Terribilis.

This is a new work which deals with the working of the Goetia spirits and their binding angels.

All seals are hand drawn by the artist Frances Nottingham. Also included are the offices of the Schemhamphorash angels with their seals too.

The work explores the formulae of their conjuration and is based upon the work of a small occult group from the borders of Wales.
