His great masterpiece, nevertheless, according to the judgment of Vasari, is the Triumph of Cæsar, represented in different pictures, which, becoming the prey of the Germans in the sackage of the city, were finally sent into England. They belonged to a great hall in the palace of S. Sebastiano, "which was completed," says Equicola, an historian of his native place, "by Lorenzo Costa, an excellent artist, who added to it all that pomp which used to attend upon a triumph, besides the spectators before wanting." But these pictures having perished, there yet remain other considerable relics from the works of Andrea, in a saloon of the castle, entitled by Ridolfi the _Camera degli Sposi_. We there behold copious productions executed in fresco, and among them several portraits of the Gonzaga family, still in good preservation; and some Genii drawn over a door-way, so joyous, animated, and airy, that nothing can be supposed to surpass them. Among collections of art we more rarely meet with specimens of him than is really believed, his genuine hand being recognized, not only by its lightness, by its rectilinear folds, or by its yellowish landscape, spread with certain minute and broken little stones; but by the skill of its design and the delicacy of its pencil. It does not appear that he produced many pictures for private exhibition, engaged as he was in works of greater magnitude, and upon many engravings. More than fifty of these last have been enumerated, for the chief part abounding with figures; labours which must have occupied a large portion of his best time. But there are some persons, as I have observed, (vol. i. p. 136,) who would considerably reduce this number, whether correctly or not posterity will, perhaps, ascertain.
