Gloucester, England: Rare Text Library / Helios, 1966. Original beige cloth with patterned papered boards, printed title label on upper board, b&w frontis. The fourth volume in a series of nine comprising the magical components of Francis Barrett’s The Magus. Edition limited to 200 numbered copies. The tenth volume of the Rare Text Library of Philosophical Research published by Helios Book Services of Gloucester, England, one of the pioneers of occult publishing in the UK in the 1960s. “The Magus” was first published in 1801 and is now recognised as one of the most influential works of the “Occult Revival” and probably the best-known magical text produced in nineteenth century Britain. The idea behind the new edition was to make the most important sections of the text – each complete within itself – available in a durable form at an affordable price. It was a monumental task, with the text having to be completely retyped, and the tables redone – only the original diagrams were copied as facsimiles. Cloth of spine slightly darkened, internally unmarked, tight and bright.
