Abramelin. According to Crowley, in his book The Confessions of Aleister Crowley, in order to perform the operations "the first essential is a house in a more or less secluded situation. There should be a door opening to the north from the room of which you make your oratory. Outside this door, you construct a terrace covered with fine river sand. This ends in a 'lodge' where the spirits may congregate." The purpose of this ritual is to invoke one's Guardian Angel. It requires at least 6 months of preparation, celibacy and abstinence from alcohol. However, it also includes the summoning of the 12 Kings and Dukes of Hell, to bind them and remove their negative influences from the magician's life.

After the Second World War the house was owned by a Major Edward Grant. In 1965, Grant committed suicide in Crowley's bedroom with a shotgun. After this a newly married couple moved into the house. The wife was blind, and after a month the man walked out, leaving the woman wandering around unable to see. In 1969 Kenneth Anger, an experimental filmmaker with an interest
