Leave this room, and make your way out of the second room until you find yourself back in the main corridor of the paintings, with David on your right. When you get to David, having him at your back, go straight ahead through the main gallery (the one hosting the Prigioni series by Michelangelo). Make your way out of the door in front at the far end. With the door behind you, turn right and follow the signs to reach the first floor. Still with me? Great! When you enter the first room, you should be able to see three works along the wall to your right. Pause for a moment at the first one, it’ll be the one nearest to you. This is the Massacre of the Innocents by the atelier of Jacopo di Cione.
