Gerard of Solo's ‘Determinatio de Amore Hereos’

The disease of love (amor hereos) proved a topic of longstanding interest at the medical school of Montpellier between the thirteenth and the fifteenth centuries. From Arnald of Villanova and Bernard of Gordon in the late thirteenth century to Valescus of Taranta and Jacques Angeli in the fifteenth, generations of Montpellier masters and students studied, expounded, and debated the lover's malady. Gerard of Solo, who received his master's degree in medicine from Montpellier in 1335, and who remained at the university to become a leading figure of medical scholasticism, compiled a university exercise on lovesickness, the Determinatio de amore hereos. Though best known to students of lovesickness as the author of a commentary on the ninth book of al-Rāzī's Liber ad almansorem, Gerard's Determinatio, which is probably his magisterial version of a disputation on love, treats the subject more systematically than does the commentary on al-Rāzī. The Determinatio, which represents how the topic of lovesickness was taught outside the framework of textual commentary, provides a useful summary of fourteenth-century scholastic medical doctrine on love.
