What is "chymes"

Chymes was a Greco Roman alchemist who lived before the third century. He is known only through fragments of text in the works of Zosimos of Panopolis and Olympiodorus of Thebes.

Some theorists state that Chymes is the eponymous founder of alchemy. Zosimos associates him with Mary the Jewess. He may likely date from this earliest period of alchemy.
