Some artists, who resided out of the kingdom, we shall notice in other schools, and in the Roman School we have already spoken sufficiently of Conca and Giaquinto; to whom we may add Onofrio Avellino, who resided some years in Rome, executing commissions for private persons, and painting in the churches. The vault of S. Francesco di Paola is the largest work he left. The works of Maja and Campora are to be found in Genoa, those of Sassi in Milan, and of others of the school of Solimene in various cities. These artists, it is to be regretted, sometimes passed the boundaries prescribed by their master. His colouring, though it might be more true to nature, is yet such as never offends, but possesses on the contrary a degree of amenity which pleases us. But his scholars and imitators did not confine themselves within their master's limits, and it may be asserted, that from no school has the art suffered more than from them. Florence, Verona, Parma, Bologna, Milan, Turin, in short, all Italy was infected with their style; and by degrees their pictures presented so mannered a colouring, that they seemed to abandon the representation of truth and nature altogether. The habit too of leaving their pictures unfinished after the manner of Giordano and Solimene, was by many carried so far, that instead of good paintings, many credulous buyers have purchased execrable sketches. The imitation of these two eminent men carried too far, has produced in our own days pernicious principles, as at an earlier period did the imitation of Michelangiolo, Tintoretto, and even of Raffaello himself, when carried to an extreme. The principal and true reason of this deterioration is to be ascribed generally to the masters of almost all our schools; who, abandoning the guidance of the ancient masters, endeavoured in their ignorance to find some new leader, without considering who he might be, or whither he might lead them. Thus, at every proclamation of new principles, they and their scholars were ready to follow in their train.
