Ahmad ibn 'Imad al-Din
No other copy has been identified, and the author is not listed in the published bibliographies of Islamic writers on alchemy. He wrote the alchemical treatise titled On the Art of the Elixir (or Fi sina‘at al-iksir), in which he describes various Chemical Reactions.
The manuscript copy is undated, but appears to be of the 17th or 18th century. In it, there is extensive marginalia giving citations from Jābir ibn Hayyān.
