Argo Pyrites

Argo Pyrites was the author of Alchemy, Ancient Art and Science.

Etymology
The name Argo derives from the Greek word argos, meaning "swift." In Greek mythology, Argo was the ship on which Jason and his companions, the Argonauts, sailed on their journey to find the Golden Fleece. Pyrite is a shiny yellow mineral, which is also called Fool's Gold, due to its resemblance to the precious metal.
