Abstract
Between the seventeenth and eighteenth centuries, the inquiry on miracles in the canonization process reveals a fundamental cooperation between medicine and religion. During the last stage of the trials, theologians, lawyers, and physicians concurred with refined reports to accomplish full analysis of the alleged miracles. The promoter of the faith had the task of doubting the supposed miracle healing on juridical, medical and theological grounds; the lawyer supporting the cause responded to any inconsistency in witnesses' depositions; the physician had the task of finding any natural causes which could lead to a natural recovery of the subject. The interplay of these tripartite disciplines underlies early modern probation of supposed miracles. In this paper I will examine the institutional and cultural consequences of the demand for evidence in canonization trials: on the one hand, the increasing role of medical experts in the assessment of miracles and the friction between them and the other members of the committee; on the other hand, the rise of a new method of inquiry in the legal arena.
