S. Giovanni e Paolo, the Villa Mattei and the Imperial Palaces
There is every reason to believe that the two city views in this drawing together form a single panorama. The bottom strip, depicting the ruins of the imperial palaces on the Palatine Hill in Rome from the southwest, would be the left half. The top strip, with the basilica and monastery of Santi Giovanni e Paolo and the Villa Mattei, constitutes the right half.
