The merit of Baldassare in grotesque is better seen at Siena than in Rome. This sort of painting, always the offspring of a whimsical fancy, was congenial to Mecherino and to Razzi; and both practised it with success. The latter seemed born to conceive and to execute it with unpremeditated facility; he painted in this style in the Vatican, and obtained the approbation of Raffaello, who was unwilling to cancel his grotesques as he did his historical compositions: he also executed some at Monte Oliveto that are highly facetious, and may be called an image of his own brain. Cristoforo Rustici and Giorgio da Siena obtained great fame in this style; but none of them equalled Peruzzi. This artist, graceful in all his works, was most elegant in grotesque; and amid the freedom that a subject wholly capricious inspires, he preserved an art which Lomazzo has studied, in order to comprehend its principles. He employs every species of idea; satyrs, masks, children, animals, monsters, edifices, trees, flowers, vases, candelabra, lamps, armour, and thunderbolts; but in their arrangement, in the actions represented, and in every other circumstance, he bridled his caprice by his judgment. He distorts and connects those images with a surprising symmetry, and adapts them as devices emblematic of the stories which they surround. This man, living in the brightest period of modern art, is in short, one of the individuals most interesting in its history. He had many pupils in architecture, but few in painting: among the latter are a Francesco Senese, and a Virgilio Romano, who are commended by Vasari for their frescos, and to whom grotesques, of uncertain origin, are sometimes attributed in Siena. Somewhat later, but certainly before the complete revival of the art at Siena, I am disposed to class a fresco painter, whom Baglione and Titi call Matteo da Siena; but who is named Matteino in his native place, that he may not be confounded with the Matteo of the fourteenth century. He lived at Rome in the time of Niccolò Circignani, in whose pictures, and in those of artists of the same class, he inserted perspectives and landscapes. The efforts of his pencil may be seen at S. Stefano Rotondo, in thirty-two historical pictures of martyrs painted by Circignani, which have been engraved by Cavalieri. Many of his landscapes are in the Vatican gallery, which are beautiful, although in the old style. At the age of fifty-five he died at Rome, where he was established in the pontificate of Sixtus V. These circumstances make it appear to me unlikely, that he had painted in the Casino of Siena, about 1551, or in the Lucarini palace, along with Rustichino: the first period I consider too early, and the latter too late.
