In addition to Fra Angelico's great crucifixion fresco in the chapter house, is a single Christ crucified, with a monk mourning, by Antonio Pollaiuolo, very like the Fra Angelico in the cloisters; but the colour has left it, and what must have been some noble cypresses are now ghosts dimly visible.

In later times many plants became connected with the name of Christ, and with the events of the crucifixion itselffacts which occasionally explain their mysterious virtues.
