A Tract of Great Price

Originally entitled "The True Teaching of Philosophy Concerning the Generation of Metals and their True Origin", this alchemical manuscript lists no specific author, first being rendered in the 1400s and providing a largely philosophical counterpart to the more hands-on approach of much Renaissance era alchemical lore. Credited to a random Sage instead of a named individual, it may instead be part of a collective philosophical tradition. Through the theories and philosophy here listed, alchemy is said to be quite literally possible, both with transmutation and other practices.
