three bearded men immersed in deep conversation stand in front of a harbor backdrop. By inscriptions on their garments they are identified as Aristotle, Ptolemy and Copernicus. Aristotle and Ptolemy occupy the left half of the picture. Aristotle, bent on a stick, and thus apparently having difficulty standing up, points to an armillary that Ptolemy, whose dark eye sockets indicate poor eyesight if not blindness, holds in front of him. The right half of the picture is occupied only by Copernicus, whose facial features, however, resemble those of Galileo. In his left hand he holds a tellurium, and with his right, he gestures towards the armillary with a certain detachment. There is a clear opposition of views as Aristotle argues the case for Ptolemy against Copernicus
