Taşköprīzāde on the (Occult) Science of Plague Prevention and Cure

Abstract

The genre of the plague treatise, still little studied, testifies to the cultural transformations that swept western Eurasia after the Black Death apocalypse of the mid-fourteenth century, with recurrent outbreaks for centuries thereafter. Ottoman contributions to this genre are exemplary: they allow us to track the emergence of an imperial-scientific early modernity. This article presents the most comprehensive and innovative Islamicate plague treatise extant, Taşköprīzāde Aḥmed’s (d. 1561) Treatise on Healing Epidemic Diseases. Therein the celebrated Ottoman polymath makes a strong case, advanced by arguments both religious and rational, for occult science as the most empirical method for preventing and curing the plague. To this end, he devotes the theoretical first half of the treatise to a critique of fatalist scholars and sufis, who prefer tawakkul to tasabbub, or blind faith to “scientific method”; the practical second half is devoted to what he considers to be the most medically effective scientific discipline of his era, lettrism (ʿilm al-ḥurūf)—a Neopythagorean science encapsulating the new “cosmological imaginary” of Western early modernity generally, wherein the world was seen by many thinkers and doers as a mathematical and hence magically tractable text. Our distaste for occult science notwithstanding, Taşköprīzāde must here be named another early modern empiricist.
