Rheumatoid arthritis in paintings: a tale of two origins

Rheumatoid arthritis (RA) is thought to be a ‘recent’ disease in that descriptions of it were only noted in the 17th century. However, a study of paintings would suggest that RA could have been present as early as the 15th century, when artists started to paint the human body accurately rather than figuratively. Thus, it was possible to deduce from their paintings the occurrence of various medical conditions. If present, RA with its typical finger deformities should be apparent. This review discusses the known occurrences of RA‐type deformities in paintings and places this in the context of the origins of the disease.
