Household recipe books were the most prevalent form of women’s authoritative
medical writing in Renaissance Europe. Among the most significant
female-authored collections from fifteenth-century Italy was that of Caterina
Sforza (1463-1509), Countess of Imola and Forlì. Two recently discovered
manuscripts shed new light on her creative praxis and the practical knowledge
she collected, developed, and tested. We argue that Caterina’s vast
miscellany of ‘secrets’ must be read intentionally within the context of a
household economy writ large, simultaneously serving the health needs and
political objectives of a Renaissance court. These discoveries highlight the
authority of experiential knowledge within the domestic realm and beyond.
Since the manuscripts were subjected to censorship, we interrogate the later
reclassification of some of Caterina’s authoritative knowledge as heterodox.
