In this scene from the legend of St. Nicholas, the saint secretly throws gold through the window of an impoverished nobleman's house to provide dowries for his three daughters (saving them from prostitution). Because the saint did not want his identity known, his act of charity was performed under cover of darkness while the man and his daughters slept.
