Cennino Cennini has frequently been partially quoted from Vasari downwards; partially quoted, but little read. He finished writing his book on the arts the 31st day of July 1437; was born soon after 1350; had been twelve years the disciple of Agnolo Gaddi, who died 1387; son of Taddeo Gaddi, the disciple and godson of Giotto, the "father of modern art." The precepts which he delivers are therefore those acquired in immediate succession from that great first master, and as the secrets of his art. We grieve to add that the work was written in prison, dated from the Stinche in Florence, at eighty years of age, and in extreme poverty; a proof among many, that the patronage of the arts in those days was not a mantle of charity of adequate dimensions to cover the wants of the numerous professors of the art; while it tells somewhat unfavourably for the gratitude of the contemporary world to know, that the one work alone of this deserted old man, the Virgin in the Hospital of Bonifacio Lupi, (so well coloured, says Vasari, that it is to this day in good preservation,) would produce a sum that would probably not only be sufficient to have paid his debts, but to have equalled the wants of no small portion of his prolonged life. The work itself seems to bear testimony to an earnest, amiable, and religious mind; there would appear, therefore, no moral fault to which to attribute his unfortunate condition. We must suppose that struggles with the world's difficulties, incompatible though they seem with art, are necessary; and that the cradle of genius must be first rocked by Want--that necessity is the great "Magister Artium;" for we find it has ever been so, even to the present enlightened age. A few favourites occupy the Goshen of patronage, who at their death are not remembered, and whose works _do_ "follow them;" and then, the works of those who have lived neglected, lived, worked, and died in penury, are eagerly sought after at any price. Such men, whilst they lived, were yet teaching a lesson in taste which the world were _slow to learn_; for it is in the nature of genius to be before the age, and in some respects to teach a novelty, which the world in not prepared to receive. Genius works on by the compulsion of its own nature, and the world is improved by it when it can no longer reward it but by a too late admiration, that reaches not, as far as we know, the dead. The complaint of Horace has been ever justified, and is still, in the eager search after works of our Wilson and Gainsborough--
