The portrait by one of the ablest engravers of the time, Stephano Della Bella, depicts (left to right) Aristotle, Ptolemy and Copernicus earnestly discussing astronomical matters. The subject of their debate is represented by the armillary sphere which Ptolemy holds in his right hand, while Copernicus holds a representation of the new heliocentric system. An arrow, barely visible on the ground to the left of the publisher’s seal, points to Copernicus.
