“One scene stayed with de Chauliac forever, obsessing him, even though, mercifully, the rest would blur; he saw a devil with wide black wings gripped by two angels, who drove it down and seemed to speak in its ears as they fell; they hit the bend of the Rhone, sending up a great, illuminated plume of water visible from Orange.

Two angels and a devil had tumbled into the water.

Three angels came up.

Forgiveness, then, was possible even for the worst.”
