I have just published Early Greek Alchemy, Patronage and Innovation in Late Antiquity, which might be of interest for readers of this forum.
The book focuses on the context in which Zosimus of Panopolis wrote his commentaries.
It also discusses the origin of alchemy according to Zosimus, its ancient history (still according to Z.) and interprets some of the symbolism found in his famous “Visions.”
