Andrea Mainardi opened school simultaneously with Malosso; and two of his pupils, Gio. Batista Tortiroli and Carlo Natali, became particularly distinguished. Both abandoned their native place, Gio. Batista going first to Rome and thence to Venice, where he formed a style which partakes most of the younger Palma, united to an evident imitation of Raffaello. Such it appears in his picture of the Slaughter of the Innocents, at S. Domenico, commendable in point of composition, and extremely well coloured. This, and a few other productions, are regarded however only as specimens of his powers, the artist dying in his thirtieth year, leaving behind him a pupil of the name of Gio. Batista Lazzaroni. This last flourished at Piacenza and in Milan, was an excellent portrait-painter, and much employed by the princes of Parma and other personages of high rank. Carlo Natali, surnamed Il Guardolino, attended the school of Mainardi, and afterwards that of Guido Reni, to which he added a long residence at Rome and Genoa, observing all that was most valuable, and exerting his own talents in the art. It was while engaged in executing a frieze in the Doria palace at Genoa, that he instructed Giulio Cesare Procaccini in the principles of painting, who had previously devoted himself to sculpture, and in him he presented us with one of the most successful imitators of Coreggio. Carlo's attachment to architecture, however, permitted him to produce few specimens, which are highly esteemed in his native state, in particular his Santa Francesca Romana, painted for S. Gismondo, a piece, which if not perfect, is certainly above mediocrity.
