Galileo and Renaissance Art
Mathematics is the Language of Nature
Edgerton has argued that Cigoli's moon was 'no doubt inspired by one of Galileo's original drawings, but a comparison between them immediately reveals that the painter did not, in fact, faithfully copy any of the drawings or, for that matter, any of the engravings published in the Sidereus nuncius.' In light of Cigoli
s professed difficulty with Latin, it is also unlikely that he relied on Galileo's written description. We do know, however, that by early 1612 Cigoli was in possession of a telescope, through which, as he proudly informed Galileo, he saw the moon 'very well.' He may, therefore, have made his own drawings of the moon in conjunction with his work on the fresco, inspired by what he had learned from Galileo and perhaps, too, in an effort to corroborate his friends discoveries in the face of mounting criticism in Rome.
