Rome had for some years seen only the two extreme styles of painting. Caravaggio and his followers were mere _naturalists_; Arpino and his scholars pure idealists. Annibale introduced a style founded in nature, yet ennobled by the ideal, and supported his ideal by his knowledge of nature. He was at first denounced as cold and insipid, because he was not affected and extravagant, or rather because great merit was never unaccompanied by envy. But though envy for a time, by her insidious suggestions and subterfuges, may derive a mean pleasure in persecuting a man of genius, she can never hope to succeed in blinding the public, who ever decide impartially on the merits of individuals, and whose judgment is not disregarded even by princes. The Farnese gallery was opened, and Rome beheld in it a grandeur of style, which might claim a place after the Sistine chapel, and the chambers of the Vatican. It was then discovered, that the preceding Pontiffs had only lavished their wealth for the corruption of art; and that the true secret which the great ought to put in practice lay in a few words: a judicious selection of masters, and a more liberal allowance of time. Hence, though somewhat tardy indeed in consequence of the death of Annibale, came the order from Paul V., to distribute the work among the Bolognese; for so the Caracci and their scholars were at that time designated; one of whom, Ottaviano Mascherini, was the Pope's architect.[71] A new spirit was thus introduced into the Roman School, which, if it did not wholly destroy the former extravagance of style, still in a great degree repressed it. The pontificate of Gregory XV. (Lodovisi) was short, but still, through national partiality, highly favourable to the Bolognese, amongst whom we may reckon Guercino da Cento, although a follower of Caravaggio rather than Annibale. He was the most employed in St. Peter's, and in the villa Lodovisi. This reign was followed by the pontificate of Urban VIII., favourable both to poets and painters, though, perhaps, more so to the latter than the former; since it embraced, besides the Caracci and their school, Poussin, Pietro da Cortona, and the best landscape painters that the world had seen. The leading masters then all found employment, either from the Pope himself, or his nephew the Cardinal, or other branches of that family, and were engaged in the decoration of St. Peter's, or their own palaces, or in the new church of the Capucins, where the altarpieces were distributed among Lanfranc, Guido, Sacchi, Berrettini, and other considerable artists. The same liberal plan was followed by Alexander VII. a prince of great taste, and by his successors. It was during the reign of Alexander, that Christina, Queen of Sweden, established herself in Rome, and her passion for the fine arts inspired and maintained not a few of the painters whom we shall mention. It must indeed be premised, that we are under the necessity of deferring our notice of the greatest names of
