"It is said that when Giotto was only a boy with Cimabue, he once painted a fly on the nose of a face that Cimabue had drawn, so naturally that the master returning to his work tried more than once to drive it away with his hand, thinking it was real. And I might tell you of many other jests played by Giotto, but of this enough." — Vasari, Lives of the Artists (1550)
c. 1267 – 1337
