It is known that Richardson expressed a wish that some historian would collect these scattered accounts relating to the art of painting, at the same time noting down its progress and decline in every age, a desideratum which Mengs in part supplied in one of his letters, briefly marking down all the respective eras. Upon this plan, as far as regarded Venetian painting, Zanetti had partially proceeded; but the general survey, in its perfect form, of the whole of the other schools, was destined to be completed by the genius of Lanzi. Here he first gives the general character of each, distinguishing its particular epochs, according to the alterations in taste which it underwent. A few artists of distinguished reputation, whose influence gave a new impulse and new laws to the art, stand at the head of each era, which they may be said to have produced, with a full description of their style. To these great masters, their respective pupils are annexed, with the progress of their school, referring to such as may have more or less added to, or altered the manner of their prototype. For the sake of greater perspicuity, the painters of history are kept distinct from the artists in inferior branches; among whom are classed portrait and landscape painters, those of animals, of flowers, of fruits, &c. Nor are such as bear an affinity to the art, like engraving, inlaying, mosaic work, and embroidery, wholly excluded. Being doubtful whether he should make mention of those artists who belong neither to the senatorial, the equestrian, nor the popular order of the pictorial republic, and have no public representation, such as the names of mediocrity; Lanzi finally decided to introduce them among their superiors, like third-rate actors, whose figures may just be seen, in order to preserve the entireness of the story. To this he was farther induced by the general appearance of their names in the various dictionaries, guides, and descriptions of cities and of galleries; and by the example of Homer, Cicero, and most great writers; Homer himself commemorating, along with the wise and brave also the less valiant--the fools and the cowards. (_Elogio_, pp. 129, 130, 131.) After having resided during a considerable period at Bassano, occupied in the superintendence of the first edition of his great work, Lanzi found himself compelled to retire to Udine, in 1796, from the more immediate scene of war; a war which subsequently involved other cities of Italy in its career. From Udine he shortly returned to Florence, where he again resumed his former avocations in the ducal gallery, about the period of the commencement of the Bourbon government.
