Cristobal Lozano presents to Pope Alexander VII an engraving of a mountain transformed into a statue of a man. Engraving by F. Spierre after Pietro da Cortona.

A man next to Lozano points to a mountain transformed into a statue of Alexander the Great. He appears not to be a self-portrait of Pietro da Cortona; he seems to represent the ancient architect Dinocrates of Rhodes, who according to Vitruvius proposed to Alexander "to transform Mount Athos into the statue of a man holding a spacious city in his left hand, and in his right a huge cup, into which shall be collected all the streams of the mountain, which shall then be poured into the sea" (De architectura, lib. II, introduction)
