premise: On your way through the Italian rooms, be sure to keep an eye peeled for Fra Angelico's glowing and stupendous Annunciation, as well as for Antonello da Messina's realistically detailed, intensely tragic Christ Sustained by an Angel, and Sandro Botticelli's The Story of Nastagio Degli Onesti.
hypothesis: The Italian rooms can be quite exhausting to go through, due to all the precious art stored there.
