Freshly typeset edition 

A cornerstone of medieval natural magic, The Secrets of Albertus Magnus gathers together a treasury of occult knowledge concerning the hidden virtues of herbs, stones, beasts, and the celestial powers that govern their operation. Long attributed to the great scholastic philosopher Albertus Magnus, this remarkable compendium stands within the tradition of the libri secretorum — books of wonders that reveal the subtle correspondences binding the natural and astral worlds.

Within its pages are found the marvellous properties of common plants and rare roots, the occult powers of gemstones and metals, the curious virtues of birds and beasts, and the influence of the seven planets upon the generation and destiny of all living things. Rooted in medieval natural philosophy and enriched by the lore of astrology and sympathetic magic, the text offers a vivid window into the learned magic of the early modern period, where science, medicine, and enchantment were yet entwined.

Part herbal, part lapidary, part bestiary, and part planetary manual, this enduring work preserves a vision of a cosmos alive with hidden forces, awaiting the discerning practitioner who knows the proper times, signs, and correspondences by which nature’s secrets may be unlocked.
