In conclusion I will enumerate the series of eighteen large pictures on the side-walls and in the lunettes at each end of the room, representing, with some few exceptions, the benefits conferred on Rome by Sixtus. The most important of these pictures are above the windows ([fig. 16]), of which there are seven on each side-wall. A Latin couplet above the picture records the subject, and allegorical figures of heroic size, one on each side, further indicate the idea which it is intended to convey.
