Before I finish this portion of my work, I would willingly pay a tribute to the numerous living professors, who have been, or who are now resident in Rome; but it would be difficult to notice them all, and to omit any might seem invidious. We may be allowed, however, to observe that the improvement which has taken place in the art of late years, has had its origin in Rome. That city at no period wholly lost its good taste, and even in the decline of the art was not without connoisseurs and artists of the first merit. Possessing in itself the best sources of taste in so many specimens of Grecian sculpture, and so many works of Raffaello, it is there always easy to judge how near the artists approach to, and how far they recede from, their great prototypes of art. This criterion too is more certain in the present age, when it is the custom to pay less respect to prejudices and more to reason; so that there can be no abuse of this useful principle. The works too of Winckelmann and Mengs have contributed to improve the general taste; and if we cannot approve every thing we there find, they still possess matter highly valuable, and are excellent guides of genius and talent. This object has also been promoted by the discovery of the ancient pictures in Herculaneum, the Baths of Titus, and of the Villa Adriana, and the exquisite vases of Nola, and similar remains of antiquity. These have attracted every eye to the antique; Mengs and Winckelmann have admirably illustrated the history of ancient sculpture, and the art of painting may be more advantageously studied from the valuable engravings which have been published, than from any book. From these extraordinary advantages the fine arts have extended their influence to circles where they were before unknown, and have received a new tone from emulation as well as interest. The custom of exhibiting the productions of art to a public who can justly appreciate them, and distinguish the good from the bad; the rewards assigned to the most meritorious, of whatever nation, accompanied by the productions of literary men, and public rejoicings in the Campidoglio; the splendour of the sacred edifices peculiar to the metropolis of the Christian world, which, while the art contributes to its decoration, extends its protection in return to the professors of that art; the lucrative commissions from abroad, and in the city itself, from the munificence and unbounded liberality of Pius VI. and that of many private individuals;[96] the circumstance of foreign sovereigns frequently seeking in this emporium for masters, or directors for their academies; all these causes maintain both the artists and their schools in perpetual motion, and in a generous emulation, and by degrees we may hope to see the art restored to its true principles, the imitation of nature and the example of the great masters. There is not a branch, not only of painting, but even of the arts depending on it, as miniature,
