Quadrivium Logo

Quadrivium Supplies is a producer and distributor of supplies for magical practitioners. Our main products are hand-made ritual oils, created according to the lunar calendar and planetary hours. A smaller collection of oils are created according to the principles of the Picatrix, a manual of astrological and talismanic magic written about 1oCE.  These Electional oils are ritually created at specific times of astrological significance, determined by an expert astrologer trained in this discipline. Another collection consists of oils made during significant astrological events, such as eclipses, equinoxes, or planetary conjunctions.   


Quadrivium Supplies is owned and operated by Catherine Diedrich, a magical practitioner of thirty-odd years with background in Roman Catholicism, NeoPaganism, hermeticism, traditional witchcraft, and American folk magic. She is assisted by a number of magical practitioners, herbalists, astrologers.  
Catherine also runs Magical Basics, a site that assists beginners in ritual magic with a variety of information on specific topics of interest, from the best way to burn resin incense to the importance of vetting when considering a magical teacher.
