Were camptodactyly and boutonniere deformity considered pathological in late fifteenth century Italy? Evidence from the sculptures of Francesco di Simone Ferrucci (1437-1493).

Representations of disease in Renaissance paintings have been discussed in medical literature, in the context of historical epidemiology, as potential sources of information about the incidence and appearance of particular conditions in earlier times. The present study seeks to show how Renaissance art can also contribute to historical nosology by casting light on the question of whether particular conditions recognized as abnormal today were understood as pathological in the past. The hands of two Renaissance Madonna figures are examined in sculptures produced by Francesco di Simone Ferrucci (1437-1493). Because the Virgin Mary was considered physically perfect by believers, and because Francesco was a successful producer of devotional sculptures for a wide audience, it is highly probable that any abnormal conditions found in the hands of Madonnas sculpted by him would not have been regarded as pathological at the time. The sculptures examined appear to depict camptodactyly and boutonniere deformity in the hands of Madonna figures. These uncommon conditions are also found in Renaissance artworks that show other individuals of high social status, but their presence in the hands of the Madonna gives the strongest indication that they were not considered pathological, due to religious belief in the Virgin's physical perfection. Examination of Madonna figures in late fifteenth century Renaissance art can contribute to historical nosology by identifying abnormal conditions that were not regarded as pathological at the time. The examples of such conditions identified in the present study are camptodactyly and boutonniere deformity.
