The architectural design was adhered to with the same pedestals and niches and the same crowning cornice of the first story.

There were to be six statues in front, but the conquered provinces were now dispensed with.

There was also to be one niche only on each flank, so that the projection of the monument from the wall was reduced more than half, and there were to be only twelve statues beneath the cornice and one relief, instead of twenty-four statues and three reliefs.

On the summit of this basement a shrine was to be erected, within which was placed the effigy of the Pontiff on his sarcophagus, with two heavenly guardians.

The whole of the statues described in this third contract amount to nineteen." Heath Wilson observes, with much propriety, that the most singular fact about these successive contracts is the departure from certain fixed proportions both of the architectural parts and the statues, involving a serious loss of outlay and of work.
