The Occult Reliquary concerns the Richel-Eldermans Collection, an archive of some 2,000 magical images and artifacts housed in the Museum of Witchcraft in Boscastle, Cornwall. Situated at the crossroads of erotic magic, ceremonial angelic conjuration, and witchcraft, the images comprise, in part, a pictorial cipher of the rituals of Ars Amatoria, a European magical order using sex magic, and the lesser-known M∴M∴, based in the Hague and Leiden. Also referenced among the collection are materials relating to A∴A∴ of Aleister Crowley. The transfixing procession of images, charms, magical seals, and ritual objects in the Collection is the work of multiple artists, and displays a high degree of magical insight and creativity. It will be of interest to students of witchcraft, Freemasonry, the Goetia, sex magic, and early twentieth century occultism.
