Mrs Merrifield and Tambroni certainly do not agree in their opinions respecting this discovery of a vehicle by Van Eyck. The Italian is rather foolishly sensitive for the honour of his country, and his sensitiveness seems to bias his judgment. He would not that a foreigner should have the merit. Tambroni believes, and probably truly, that Vasari never thoroughly read Cennino; but he bears testimony to the _noble_-mindedness of Vasari--"Whence," says he, "we are constrained to believe that he merely glanced lightly over the titles to the chapters of part of the manuscript; and that, thinking it useless, he did not care to examine and investigate the whole work. For this reason it cannot be supposed that this noble-minded man, so zealous for the honour of his country, and whose every effort had been directed to make it pre-eminent, would withhold from one of his fellow-countrymen the just fame which he deserved by so valuable a work. Nor do I intend here to reprove him, or to lessen his glory. I shall only say that he committed a great error in not having examined the work of this old master: for then, perhaps, he would not so easily have given the credit of those things to strangers which certainly were known in his own beautiful Tuscany, and in all Italy, as I shall hereafter study to prove." Yet he does not hesitate after this to charge "this noble-minded man" with fabricating "a romance or tale of the imagination." But he misquotes Vasari. As Mrs Merrifield justly observes, "he takes only part of Vasari's account into consideration, instead of stating the whole, and reasoning on it as Lanzi has done. Vasari does not limit Van Eyck's discovery to the simple fact, that he had discovered that linseed and nut oils were more drying than any he had tried; but he adds, "these then, _boiled with his other mixtures_, made the varnish, which he, as well as all the other painters of the world, had so long desired." It is very singular that this most important passage should have been entirely omitted by the editor, (Tambroni.) It is in _these mixtures_ that the secret consisted, not in using the oils; and we may certainly conclude that the process of Van Eyck was very different from that of Theophilus and Cennino, both of whom used linseed oil without the mixture of any other substance. "It will be observed that lake even was used by Cennino without any addition to increase its drying qualities. The only dryer he mentions (as such) is verdigris, which he used for mordants only. The difference in the texture of pictures painted in the Flemish (that is, Van Eyck's manner) and those painted with oil alone, or with the modern megilp, (oil and mastic varnish,) is so well known that it is scarcely necessary to allude to it.
