Medicine and Religion c.1300 The Case of Arnau de Vilanova

Much of this argument relies on language analysis and on a close study of unedited manuscript sources. By juxtaposing the spiritual writings and the medical output of two learned physicians — Arnau de Vilanova (c. 1238-1311) and Galvano da Levanto (fl. 1300) — Dr Ziegler shows that they saw a medical purpose, namely to ensure the spiritual health of their audience and to reveal the mysteries of God and creation. When entering the spiritual realm, both brought to it a medical framework and extended their medical knowledge and curative activities from body to soul.

By examining preachers’ manuals and sermons, the author suggests that a growing tendency emerged among clerics in general and preachers in particular to appropriate current medical knowledge for spiritual purposes and to substantiate their extensive use of medical metaphors, analogies and exempla by citing specific medical authorities.
