The Deceit is a work of fiction. However, I have drawn on many real, historical, archaeological and cultural sources for this book. In particular:
The Sacred Magic of Abra-Melin the Mage is a book of spells and curses, compiled by a Jewish Kabbalist, Abraham of Worms, in fifteenth-century Germany. Various versions of the text survive in libraries across Europe. In occult circles the magic of Abra-Melin is regarded as the most ‘dangerous’ of all hermetic rituals.
Aleister Crowley (1875–1947) was a British mountaineer, adventurer, drug-addict and black magician, and for a time a member of the Hermetic Order of the Golden Dawn, alongside artists such as the Irish poet, and Nobel laureate, W B Yeats. In 1924 a disciple of Crowley’s died in Crowley’s house in Cefalu, Sicily — allegedly after Crowley had fed him the blood of a cat.
The little town of Akhmim is possibly the oldest inhabited site in Egypt. Regarded as the cradle of alchemy, and as one of the birthplaces of Gnostic and Coptic Christianity, Akhmim also, in antiquity, enjoyed a reputation as being home to the greatest magicians in Egypt. Despite its extraordinary history, Akhmim has never been properly excavated by archaeologists.
