The Golden Tractate of Hermes is one of the shorter variety of alchemical works ever made, but that doesn’t make it worth a read; along with Pontanus’ and Artephius’ works (with allusions infrequently in other materials) it seeks to explain alchemy without all of the symbolism and veils most prevalent therein- a task it performs with some degree of success.

It is delivered in the form of a dialogue between various great antiquated minds in science and philosophy, despite the fact that it was created no earlier than perhaps the late 800sAD and probably in the early 900s. It expounds and elaborates upon alchemical principles and truths that would become commonplace centuries later in virtually all Renaissance era works of this type.
