"The [body [of St. Sebastian ] is bound with one arm high up, the other low down, to a column ; the whole frame writhes in such a way as to display almost all of the back. In all parts of the person there is evidence of suffering, and all from one arrow that sticks in the middle of the body. I am no judge, because I do not understand drawing, but looking at the limbs and muscles the figure seems to me to be as natural as a corpse."
