Above every other branch of inferior painting, however, the ornamental and perspective then flourished at Bologna. This art, as we have stated, after the solid foundations on which it had been placed by Dentone and Mitelli, aimed too much at a pleasing and beautiful, without consulting a natural effect. But the school did not all at once deteriorate, being some time maintained by imitators of some of the most correct models. In this number Zanotti extols Jacopo Mannini, a most accurate artist, who decorated a chapel at Colorno for the Duke of Parma, in which the Cav. Draghi was employed as figurist, whose genius was at once as eager and rapid as Mannini's was slow. Much like two steeds of opposite temper yoked to the same vehicle, their sole occupation seemed that of biting and kicking each other; and it became necessary to separate them, the slow one being sent back to his native Bologna, where owing to this blemish he never met with any encouragement. Arrigo Haffner, a lieutenant, with Antonio his brother, who died a Philippine friar in Genoa, were also followers of Mitelli in delicacy and harmony of colour. They had been much employed at Rome under Canuti, their master in figures, and the former was chosen by Franceschini to paint the perspectives in the church of Corpus Domini. They produced also a good deal at Genoa and its state, sometimes with one, sometimes with another of the more eminent figurists. Antonio acquired most reputation, superior perhaps in all but invention to his brother, particularly in the sweet union of his tints, as well as in the estimation of distinguished personages. He was called by the Grand Duke Gio. Gastone to Florence, to consult him respecting the altar of _pietre dure_, intended for the chapel of the Depositi at S. Lorenzo.
