In Santa Maria del Fiore a stone half as big as a mule's pack fell from one of the rough windows high up on the cupola, towards the sacristy where the priests robe themselves; it fell just at the side of the choir. It happened at the hour when the priests robe themselves to say vespers, but although the church was already full of people, it hurt no one, which was a marvellous thing. God was pleased to be so gracious.
