Quick Summary

Synesius of Cyrene was a Byzantine alchemist and bishop who lived in the 4th century AD. He is noted as one of the authors represented in a compendium of alchemical writings likely compiled in Byzantium. While alchemy involved practical skills from artisans and theoretical ideas from Greek philosophy, Synesius is associated with the notion that alchemy could be a mental operation, distinct from the science of matter. His writings contributed to the development of alchemical thought, which sought to transform metals and find cures for diseases.123
