-St. Bonaventure, Life of St Francis of Assisi 6

“A cricket used to perch on a fig tree beside the cell of the man of God at St. Mary of the Portiuncula and sing, arousing with its songs the Lord's servant to sing more frequently the divine praises, for he had learned to marvel at the Creator's magnificence even in insignificant creatures. He called it one day, and it flew upon his hand as if it had been taught by God. He said to it: "Sing, my sister cricket, praise the Lord Creator with your joyful song!" It obeyed without delay and began to sing; nor did it stop until at his command it flew back to its usual place. There it remained for eight days, coming each day, singing and returning, all at his command. Finally the man of God said to his companions: "Let us give our sister cricket permission to go away now, for she has cheered us enough with her singing and has aroused us to praise God over the space of eight days." With his permission, it departed and never appeared there again, as if it did not dare to disobey his command in the slightest way.”
