Celestial Messenger: Planetary Folk Magic of Mercury


Far-darting upon winged sandals from the three-way crossroads where Greek Hermes, Roman Mercury and even some vestiges of Egyptian Thoth meet, Mercury the planet can truly be considered thrice-great.

Ruling all communication, all languages, mathematics, sciences, philosophy, and even the teaching of magic itself, Mercury is very much a magician's planet. But fluid, dynamic Mercury also governs hermaphrodites and those who practice the alchemy of balancing and re-articulating masculine and feminine forces within and without themselves. 

At once trickster and teacher, Mercury is both a wise librarian and a charming devil at the crossroads. Perhaps increasingly known in popular culture by the upsets and upheavals of Mercury Retrograde, this supremely mutable Messenger of the Gods carries both good and bad news.

In this illustrated lecture - taught by professional diviner, consultant sorcerer, and historian of magic, Dr Alexander Cummins - we will explore various folk magical means of working with Mercury and its spirits to adapt, to connect, to understand, and to communicate. These techniques are drawn from ancient incantations, medieval and early modern handbooks of ritual magic and spirit conjuration, and even some modern approaches to surviving and even thriving during the next Retrograde!
