This article examines the dedicatory epigram of the earliest and most important witness to the Greek alchemical corpus, the tenth-century manuscript donated by Cardinal Bessarion to the Republic of Venice, Biblioteca Nazionale Marciana MS gr. 299, as a window onto the cultural coordinates of the manuscript’s middle Byzantine readers. Scrutiny of the epigram’s meter, language, literary conventions, and the handwriting of the scribe who copied it into the manuscript point to a tenth-century date not only for the manuscript but also (...) for the epigram itself and make it possible to situate the epigram, and with it the alchemical manuscript that contains it, within the mainstream of middle Byzantine elite culture.

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.

Thābit b. Qurra, a Sabian of Ḥarrān, and his descendants remained in their ancestral religion for six generations. Why did they persist despite pressure to convert? This article argues that religious self-identification as a Sabian could be a distinct advantage in Baghdad’s elite circles. It focuses on Thābit’s great-grandson Abū Isḥāq Ibrāhīm b. Hilāl al-Ṣābī and his poetry as collected by al-Thaʿālibī. Two members of the family who did convert are also considered by way of contrast.

This essay analyzes the known evidence for Byzantine engagement with what are conventionally termed “alchemical” texts, theories, and practices of the Islamic world. Much of the evidence is difficult to date. Nevertheless, the aggregated direct, indirect, and circumstantial evidence suggests at least some engagement by Greek-speaking scholars throughout the Middle Ages. This engagement took various forms, from the use of Arabic, Persian, and Turkish terminology to the adaptation of whole Arabic treatises in Greek. Sometimes the Byzantine texts emphasize their Islamicate (...) sources, and sometimes they do not mention these sources at all. The resulting picture is still fragmentary, but it indicates that medieval Greek-speaking scholars were active in the circulation of chemical knowledge and techniques in the Mediterranean and Middle East. Byzantium, therefore, should no longer be left out of research into long-term patterns in the history of science. (shrink)
