Bologna, no less than those of Siena, of Pisa, and other places, had learned the art from the Florentines, he formed a false system, the absurdity of which he did not immediately perceive; but he at last discovered it, as Signor Piacenza observes, and succeeded in escaping from its trammels. The most ingenious builders of systems have subjected themselves very frequently to the same disadvantage, and the history of literature abounds with similar instances. Having examined this sophism, I cannot subscribe to the opinion of Baldinucci; but shall comprise my own opinion in two propositions:--The first is, That the improvement of painting is not due to Florence alone. It has been remarked, that the career of human genius, in the progress of the fine arts, is the same in every country. When the man is dissatisfied with what the child learned, he gradually passes from the ruder elements to what is less so, and from thence, to diligence and precision; he afterwards advances to the grand, and the select, and at length attains facility of execution. Such was the progress of sculpture among the Grecians, and such has been that of painting in our own country. When Correggio advanced from laborious minuteness to grandeur, it was not necessary for him to know that such was the progress of Raffaello, or, at any rate, to have witnessed it: in like manner, nothing more was wanting to the painters of the thirteenth and fourteenth centuries, than to learn that hitherto they had pursued a wrong path; this was sufficient to guide them into a better path, and it was not then untried; for sculpture had already improved design. We have, in fact, seen the Pisani, and their scholars, preceding the Florentines; and, as their precursors, diffusing a new system of design over Italy. It would be injustice to overlook them in the improvement of painting, in which design is of such importance; or to suppose that they did not signally contribute to its improvement. But if Italy be indebted solely to Cimabue and Giotto for its progress, all the good artists should have come from Florence. And yet, in the cathedral of Orvieto (to instance the finest work, perhaps, of that age), we find, from the beginning of the fourteenth century, many artists from various other places, who would not have been called to ornament such a building, had they not previously enjoyed the reputation of able masters.[53] Add to this, if we are to derive all painters from those two masters, every style of painting should resemble that of their Florentine disciples. But on examining the old paintings of Siena, of Venice, of Bologna, and of Parma, they are found to be dissimilar in idea, in choice of colouring, and in taste of composition. All, then, are not derived from Florence.
