Viani opened school opposite that of Cignani, and taught to some extent; in which he was succeeded by his son Domenico, whose life was written by Guidalotti, who, in point of merit, prefers him to his father. Few will subscribe to this opinion, he not having attained to that exactness, much less to that dignity of design, exhibited by his father; and inferior to him in the nature, truth, and clearness of his colouring. Still he possessed a grander character in his outline, a stronger execution, like Guercino's, more splendid ornaments, like the Venetians, whom he assiduously studied in their own capital. There is his St. Antony, at S. Spirito, in Bergamo, in the act of convincing a sceptic by a miracle; a surprising picture, extolled by Rotari and Tiepolo, and perhaps the best work which he left at Bologna. At the same place is his Jove, painted on copper, for the Casa Ratta, besides other works in private houses, to which he chiefly devoted himself. His fellow-pupils in the paternal school were four Clementine academicians, whose altar-pieces we find mentioned among the "Paintings of Bologna." These were Gian Girolamo Bonesi, who renounced both the name and style of Viani, in order to follow Cignani, and complained of being included in Viani's school. However this might be, his pictures pleased, by adding to the beautiful a peculiar delicacy and sweetness that characterize him. Carlo Rambaldi, imitating both the Viani, was not the less employed by Bonesi; and pictures of both are met with, especially half-length figures, in select galleries at Bologna, and a few historical pieces in the royal collection at Turin. Antonio Dardani possessed more universal talent than either of the preceding, but was not equally refined. Pietro Cavazzi was a fine connoisseur in prints, and only on this account was celebrated in Italy and abroad. Tronchi, Pancaldi, Montanari, with others, not admitted into the Clementine academy, may be found mentioned in Crespi. No one, I imagine, would desire an account of the under graduates, when the academicians who enjoyed the first rank, were many of them, according to Zanotti, only artists of mediocrity.
