This genial architect, in whose style all the graces were combined with dignity and strength, prepared a new design at Leo's request.

Vasari, referring to this period of Peruzzi's life, says: "The Pope, thinking Bramante's scheme too large and not likely to be in keeping, obtained a new model from Baldassare; magnificent and truly full of fine invention, also so wisely constructed that certain portions have been adopted by subsequent builders." He reverted to Bramante's main conception of the Greek cross, but altered the details in so many important points, both by thickening the piers and walls, and also by complicating the internal disposition of the chapels, that the effect would have been quite different.

The ground-plan, which is all I know of Peruzzi's project, has always seemed to me by far the most beautiful and interesting of those laid down for S.Peter's.

It is richer, more imaginative and suggestive, than Bramante's.

The style of Bramante, in spite of its serene simplicity, had something which might be described as shallow clearness.
