But Cattanio's chief praise consists in his education of Gio. Bonatti, and in his recommendation of him to Card. Pio, who greatly assisted him, by placing him first at Bologna under Guercino, afterwards under Mola at Rome. He long supported him also at Venice, studying the heads of that school; besides defraying his pictoric tours through Lombardy, and giving him the custody of his paintings at court. In fact, he bestowed upon him such favours that the public, considering him as the dependant of that prince, always termed him _Giovannino del Pio_. At Rome he was esteemed among the best of his age; select, diligent, learned in the different styles of Italian schools; the view of which, during his picturesque tour, he declared was highly advantageous to him. And true it is that the painter, like the writer, is formed by the study of great models; but the one may behold them all collected in the same library, while the other has to seek them in different cities, and in every city to study them at different places. At Rome his only public works are a picture at the church dell'Anima, a history of S. Carlo at the Vallicella, and an altar-piece of S. Bernardo, at the Cisterciensi, highly commended in the Guide of Rome. The rest of his works, and they are but few, belong to private persons; his health declining at the age of thirty-five, he lingered eleven years afterwards, and died at Rome. Lanfranco likewise supplied a pupil to this school, called by Passeri, Antonio Richieri, a Ferrarese. He followed his master to Naples and Rome, where he painted at the Teatini after the designs of Lanfranco:--the sole information I have been enabled to collect respecting his paintings. I am well aware that he devoted himself to engraving, as we learn also from Passeri, and that at Naples he engraved an altar-piece by his master, which was rejected by the person who gave the commission for it. There is more known of Clemente Maiola, whom the Ferrarese assert to be their fellow-citizen and pupil to Cortona. He conducted many works at Ferrara; one of S. Nicola supported by an angel, in the church of S. Giuseppe. He is moreover mentioned as a fine pupil of Pietro, in the Notizie of M. Alboddo, for works there extant. Titi gives account of others left in Rome at the Rotonda and in other temples; but he differs respecting his master, declaring that he was instructed by Romanelli.
