This painting, Anatomy of the Heart (¡Y tenía corazón! [Anatomía del corazón]), by Spanish painter Enrique Simonet (1866-1927), in spite of its having an ostensibly naturalistic subject matter, has always struck me as having just a bit of madness about it. What is the anatomist thinking as he holds his subject’s heart in his hand? Are the really just scientific thoughts? I originally blogged it in a 21 December 2018 post at Infernal Wonders.
