The Cav. Antonio Campi was instructed by his brother in architecture and painting, in the former of which he employed himself more than Giulio. This was useful to him in the distribution of his large works, where he often introduced perspective views of great beauty, and displayed great skill in foreshortening. A fine specimen of his powers is to be seen in the sacristy of S. Pietro, with that beautiful colonnade, above which appears the chariot of Elias in the distance. Antonio was also a modeller, an engraver, and the historian of his native state, whose annals, enriched with many of his copper-plates, he published in 1585. In the Campi family, therefore, he will be found to occupy the same place as Agostino among the Caracci, an artist of great versatility, conversant with polite letters. He was well known and appreciated by Agostino, who engraved one of his most beautiful productions, the Apostle of the Gentiles in the act of raising a person from the dead. It is placed at S. Paolo in Milan, a noble church, where all the Campi, in the same manner as at S. Sigismondo, are seen in competition with each other. Antonio there appears to great advantage, no less in the forementioned picture than in that of the Nativity, though the frescos adorning the chapels, ascribed to him, are deficient in accuracy. Thus he also produced works of unequal merit at S. Sigismondo, as if he wished to shew that he knew more than he was ambitious of expressing. His most familiar model, as is remarked also by Lomazzo, was Coreggio, and the feature that he most aimed at expressing was that of grace. To this he often attained in point of colouring, but was less happy in design, where, owing to his study of elegance, he at times becomes disproportionately thin, and at others, in order to display his power, he exhibits a foreshortening somewhat out of place. He is still more mannered in his more robust subjects, and occasionally borders upon heaviness and vulgarity, into which his imitation of Coreggio's grandeur, more difficult, perhaps, than his grace, doubtless betrayed him. There are many of these exceptions, however, along with his incorrectness of design, so often discernible, which are to be attributed to his numerous assistants, employed in these vast undertakings. But this will not apply to his over-grouping, which is so remarkable in some of his compositions, nor to the introduction of caricatures into his holy histories, which is a sort of jesting out of season. In a word his genius was vast, spirited, resolute, but often in want of the rein; and in this respect, and generally in what relates to pictorial learning, we should do wrong to put him in competition with Lodovico Caracci.
