Abstract
Abstract: This article investigates several discussions of “chemistry,” understood as an analysts’ category referring to theories and practices dealing with the structure and transformation of matter. By reading these texts (a treatise defending kīmiyāʾ by al-Fārābī, the famous passage from Ibn Sīnā’s Shifāʾ on transmutation, Ibn Taymiyyah’s fatwā against kīmiyāʾ , Michael Psellos’s treatise On Making Gold , and the same author’s Accusation against a sitting Patriarch of Constantinople), the article aims to lay the groundwork for integrating the historiography of Byzantine and Arabic alchemy into a wider western Eurasian intellectual history.
