But with all his pains he has not satisfied the public expectation, as is observed by Signor Piacenza, who published the splendid Turin edition of Baldinucci as far as the life of Franciabigio, accompanied with very useful notes and dissertations.[50] It is alleged, that to make this tree fair and flourishing, he has inserted in it branches dexterously stolen from his neighbours, who have not failed to reclaim their property. I rejoice to write in an age when the opinions of Baldinucci have few followers even in Florence. The excellent work entitled "_Etruria Pittrice_," composed and applauded in that city in proportion as it is free from the prejudice of former times, proves this sufficiently. Following in like manner the light of history and of reason, unswayed by party spirit, I shall in the first place observe, that among all the scholars of Cimabue, I do not find any named by Vasari, but Giotto and Arnolfo di Lapo, concerning whom it is certain that the historian was in error. Lapo and Arnolfo are the names of two different sculptors, _disciples_ of Niccolò Pisano, who, being already versed in the art, assisted him in 1266 to adorn with history pieces the pulpit of the cathedral at Siena, an authentic document of which remains in the archives of the work.[51] Thus this branch of the tree belongs to Pisa, unless Cimabue have a claim to it, by contributing in some degree to the instruction of Arnolfo in the principles of architecture. Andrea Tafi was the pupil of Apollonius, a Greek artist, and assisted him in the church of St. John, in some pieces of mosaic, from scriptural history, which, according to Vasari, are without invention and without design; but he improved as he proceeded, for the last part of the work was less despicable than the beginning. Cimabue is not named in these works, nor in what Tafi afterwards executed without assistance; and as he was old when Cimabue began to teach, I cannot conceive how he can be reckoned the scholar of the latter, or a branch from that root. Gaddo Gaddi, says Vasari, was contemporary with Cimabue, and was his intimate friend, as well as that of Tafi; through their friendship he received hints for his improvement in mosaic. At first he followed the manner of the Greeks, mingled with that of Cimabue. After long working in this manner, he went to Rome, and there improved his style, while employed on the façade of S. Maria Maggiore, by his own genius, assisted in my opinion by imitating the ancient workers in mosaic. He also painted some altar-pieces, and I saw at Florence one of his crucifixions, of a square figure, and very respectable workmanship. This circumstance induces me to consider Gaddo, in some measure, among the imitators of Cimabue, but not one of his pupils; for it appears to me unjust, should a contemporary communicate with an artist either as a friend, or for the sake of advice on the art, to set him immediately down as a branch from that stock.
