The Art of Drawing Spirits into Crystals

This brief text, associated with Trithemius, belongs to the tradition of ceremonial and divinatory magic focused on scrying and spirit communication. It became influential in later occult literature because it describes, in practical and symbolic terms, the use of crystals for receiving visions and obtaining hidden knowledge.

Johannes Trithemius (1462–1516) was a German abbot, humanist, and scholar whose writings became influential in Renaissance esotericism. He is especially associated with cryptography, angelology, and occult learning, and his works were widely read by later practitioners of ceremonial magic.
