By the second day Michelangelo began to worry; and by the second night he was in a state of panic: he could see nothing out of the afflicted eye. At dawn Argiento went to Jacopo Galli. Galli arrived with his family surgeon, Maestro Lippi. The surgeon carried a cage of live pigeons. He told Argiento to take a bird out of the cage, cut a large vein under its wing, let the blood gush into Michelangelo's injured eye.

The surgeon came back at dusk, cut the vein of a second pigeon, again washed out the eye.
