The pictorial representation of internal body parts in ancient Greek iconography is both rare and unconventional, often diverging from classical aesthetic principles and theories of representation. Yet, despite the loss of scientific illustrations such as anatomical plates and manuscript drawings, this visual repertoire is not entirely absent. In this talk, I will explore surviving iconographic material—including mosaics, paintings, and sculptures—focusing on four key categories of evidence: (1) the Asarotos oikos (unswept house), (2) depictions of skinned animals, (3) votive body parts, and (4) enigmatic vase paintings that appear to depict internal organs. These images offer valuable, if elusive, insights into ancient conceptions of the body's interior.
