Such was the state of the art, when, towards the decline of the sixteenth century, Lodovico Carracci,[54] with his cousins Agostino[55] and Annibale, founded at Bologna that eclectic school, which by selecting the beauties, correcting the faults, supplying the defects and avoiding the extremes of the different styles, attempted to form a perfect system. But as the mechanic part was their only object, they did not perceive that the projected union was incompatible with the leading principle of each master. Let us hear this plan from Agostino Carracci himself, as it is laid down in his sonnet[56] on the ingredients required to form a perfect painter, if that may be called a sonnet which has more the air of medical prescription. 'Take,' says Agostino, 'the design of Rome, Venetian motion and shade, the dignified tone of Lombardy's colour, the terrible manner of Michael Angelo, the just symmetry of Raphael, Titiano's truth of nature, and the sovereign purity of Corregio's style: add to these the decorum and solidity of Tibaldi, the learned invention of Primaticcio, and a little of Parmegiano's grace: but to save so much study, such weary labour, apply your imitation to the works which our dear Nicolo has left us here.' Of such advice, balanced between the tone of regular breeding and the cant of an empiric, what could be the result? excellence or mediocrity? who ever imagined that a multitude of dissimilar threads could compose an uniform texture, that dissemination of spots would make masses, or a little of many things produce a legitimate whole? indiscriminate imitation must end in the extinction of character, and that in mediocrity,--the cipher of art.
