Perhaps one of the most unappealing portraits of the Renaissance is Quentin Massys’s An Old Woman. Scholars have long been perplexed on the nature of the portrait; was this woman real, a study of the grotesque, or was Massys satirizing women who tried too hard to remain young? Recent research indicates that the painting is not a copy of Leonardo’s da Vinci grotesque drawings but rather Da Vinci copied Massys, an unexpected find. Art historians are not the only ones drawn to this work, medical researchers have contributed to the discussion as well. They believe that the woman was suffering from Paget’s disease, bone abnormalities that lead to deformities. Her actual identity, if there is one, remains unknown. The painting is one of the most popular pieces on display in the National Gallery, London.
