Quadrivium Supplies, Inc. is a creator and wholesale distributor of supplies for ritual magicians. Our main product is Quadrivium Oils™, which are hand-made ritual oils, created according to the lunar calendar and planetary hours. Certain oils are electional, created at times determined by an expert astrologer trained in this discipline.

Wholesale orders for Quadrivium Supplies oils can be placed here – new customers will need to email us through the website to access the ordering system.

Quadrivium Supplies is owned and operated by Catherine Diedrich, a magical practitioner with a background in Roman Catholicism, NeoPaganism, hermeticism, traditional witchcraft, and American folk magic. She is assisted by a number of magical practitioners, herbalists, and a very good astrologer.
