About Us

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.

Each Quadrivium Oil™ is hand made, sealed, labeled, and packaged securely in a sealed bag with an insert that provides information about that particular oil, known or potential allergens/irritants in the oil, and other useful information. The oils are made with entirely natural ingredients, without chemicals, synthetics, or solvents.

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 hates talking about herself in the third person, and is assisted by a number of magical practitioners, herbalists, and one very good astrologer.

We are always happy to interact with our customers on our Facebook page and our Twitter account. An archive of interviews and lectures given by the owner of the company is being created.
