In treating of the Florentine School we took occasion to enter into a brief examination of the pictoric education of Vinci, of his peculiar style, and of his residence in different cities, among which was mentioned Milan, and the academy which he there instituted. He arrived in that city, according to the testimony of Vasari, in the year 1594, the first of the reign of Prince Lodovico Il Moro; or rather he resided there, if not altogether, at least for the execution of commissions, from 1482, as it has been recently supposed,[48] and left it after its capture by the French in 1499. The years spent by Lionardo at Milan were, perhaps, the happiest of his life, and certainly productive of the most utility to the art of any in the whole period of his career. The duke had deputed him to superintend an academy of design, which, if I mistake not, was the first in Italy, which gave the law to the leading ones in other parts. It continued to flourish after the departure of Vinci, was much frequented, and formed excellent pupils, maintaining in the place of its first director, his precepts, his writings, and his models. No very distinct accounts indeed of his method have survived; but we are certain that he formed it on scientific principles, deduced from philosophical reasoning, with which Vinci was familiar in every branch. His treatise upon painting is esteemed, however imperfect, as a kind of second canon of Polycletes, and explains the manner in which Lionardo taught.[49] We may also gather some knowledge of it from his other numerous and various writings, which, having been left to the care of Melzi, and in the course of time distributed, now form the ornament of different cabinets. Fourteen volumes of these presented to the public, are in the Ambrosian collection, and many of them are calculated to smooth the difficulties of the art to young beginners. It is further known that the author, having entered into a familiar friendship with Marcantonio della Torre, lecturer of Pavia, united with him in illustrating the science of anatomy, then little known in Italy, and that he represented with the utmost exactness, in addition to the human figure, that of the horse, in a knowledge of which he was esteemed quite unrivalled. The benefit he conferred upon the art by the study of optics is also well known, and no one was better acquainted with the nature of aërial perspective,[50] which became a distinctive and hereditary characteristic of his school. He was extremely well versed in the science of music, and in playing upon the lyre, and equally so in poetry and history. Here his example was followed by Luini and others; and to him likewise it was owing that the Milanese School became one of the most accurate and observing in regard to antiquity and to costume. Mengs has noticed before me that no artist could surpass Vinci in the grand effect of his chiaroscuro. He instructed his pupils to
