For 10 points, name this "faultless painter" of Madonna of the Harpies.
Vasari tells how when this man's wife wouldn't sit still for a picture, he painted himself. This man's Last Supper takes place in a room with a high arched ceiling and three windows above the table. A figure on a balcony outside the window is leaning his arm on the ledge and looking towards another, who is turning around to face the viewer.  St. Francis is to the right and St. John to the left of a title figure in another work. Angels grab the legs of that figure, who is standing on a pedestal into which is carved this man's signature and the opening words of a hymn dedicated to Our Lady of the Assumption. Carved into the edges of the pedestal are screaming winged figures, which give the painting its name.  For 10 points, name this "faultless painter" of Madonna of the Harpies.
