St Bernardino of Siena
by LORENTINO D'AREZZO, Fresco
The large two-light window of the Cappellla Maggiore was the work of Niccolò Tedesco made in 1417. It was destroyed in the rarly seventeenth century. The window probably included effigies of Franciscan saints to which, following the canonization of St Bernardino in 1450, Lorentino, a collaborator of Piero della Francesca, added an image of the new saint against a “mille fleur” background in the window embrasure of the Cappella Maggiore of San Francesco, Arezzo.
