Vasari relates of Ugolino Senese, that he was a tenacious follower of the Greek style, and inclined more to imitate Cimabue than Giotto. He does not on this account, indeed, expressly say, that he had been his scholar; he rather hints that he had other instructors at Siena, for which reason it will be better to consider him under that school, there being no reason to doubt that he belonged to it. In that of Bologna we should also class Oderigo, who, as a miniature painter, was more likely to employ some other master than a painter in fresco like Cimabue. In the mean time it is useful to reflect, that were the method of Baldinucci to be pursued, nothing authentic would remain in a history of painting; and the schools of the early masters would increase beyond all limits, were the scholars of each master to be confounded with his friends, acquaintances, and contemporaries, who paid attention to his maxims. It is still more strange to peruse the account of the connexion between the first and secondary branches of the tree, or if one may use the expression, between the children and grandchildren of Cimabue. There is nothing natural in their succession, and the labour is wholly useless which derives the professors of every fine art, of whatever country, past, present, and to come, from one individual. F. Ristoro and F. Sisto were eminent architects, who rebuilt the grand bridges of the Carraja and the Holy Trinity, about 1264, when Cimabue was twenty-four years of age. Baldinucci writes of both, that they were, perhaps, disciples or imitators of Arnolfo, from the state of their works. But how comes he to found on a _perhaps_, what he, a little before, had vaunted as a _clear demonstration_? And then, on what does this _perhaps_ rest? Is it not more probable that Arnolfo, and Cimabue himself, imitated them? That Fra Mino da Turrita should appear in his tree as a scholar of Tafi, and as posterior to Cimabue, is no less absurd. In 1225, a date omitted by Baldinucci, Mino wrought in mosaic at Florence, fifteen years before Cimabue was born. In his old age he commenced a similar work in the cathedral of Pisa, "in the same style in which he had executed his other labours," says Vasari, who adds, that Tafi and Gaddi (both his inferiors in age and reputation) assisted him. The work was "little more than begun," from which we may infer that they were not long associated. It seems to me extraordinary how Baldinucci could assert, "it appears that Vasari imagined that Mino was the pupil of Andrea Tafi," which is contrary to fact: instead of the "_clear demonstration_," which he promised, he has amused us with "_it appears_," which is evident only to himself. At length, wishing to make us believe that Giovanni Pisano the sculptor is a _pupil_ of Giotto the painter, he again turns to Vasari, from whom he brings evidence that Giovanni, having completed his work in the cathedral of Arezzo, and being then established at Orvieto, came to
