Zosimos is the oldest alchemical author for whom there are genuine, uncontested, treatises. He lived in Panopolis, in upper Egypt, at the end of the 3rd century AD, or the beginning of the 4th. In Arabic his name is written in various forms, including Risimus, Rusim, Rusam, and Zusimus.
NLM has a fragment of an Arabic treatise on numerology attributed to Zosimos, in addition to a treatise on alchemy described elsewhere (MS A 70, item 14).
No other copy has been identified.
The top six lines on this folio are the end of an anonymous and untitled Persian treatise on winds and rain, while the text written diagonally over the rest of the folio is the beginning of an Arabic treatise on numerology attributed to Zosimos (3rd to 4th cent.
