Plutarch's mention of Hermes Trismegistus dates back to the 1st century AD, and Tertullian, Iamblichus, and Porphyry were all familiar with Hermetic writings.
In 1614, Isaac Casaubon, a Swiss philologist, analyzed the Greek Hermetic texts for linguistic style.
Moreover, Cudworth noted Casaubon's failure to acknowledge the codification of these treatises as a late formulation of a pre-existing oral tradition.
The word Hermetic was used by John Everard in his English translation of The Pymander of Hermes, published in 1650.
Lost Greek texts, and many of the surviving vulgate books, contained discussions of alchemy clothed in philosophical metaphor.
In 1945, Hermetic texts were found near the Egyptian town Nag Hammadi.
The microcosm is oneself, and the macrocosm is the universe.
The macrocosm is as the microcosm and vice versa; within each lies the other, and through understanding one (usually the microcosm) a person may understand the other.
