Decameron, the story of monk Albert

Friar Alberto deceives a woman into believing that the Angel Gabriel is in love with her. As an excuse to sleep with her, Friar Alberto tells her that Gabriel can enter his body. Afterward, for fear of her kinsmen, he flings himself out of her window and finds shelter in the house of a poor man. The next day the poor man leads him in the guise of a wild man into the piazza, where, being recognized, he is apprehended by his fellow monks and imprisoned.
