believing that both produced works, which owing to a similarity of natural taste, selection and admiration of the same object, might be mistaken for specimens of the same hand. Of this number is his own portrait, at an age which corresponds with this period, in the ducal gallery, a head that surpasses every other in that room for energy of expression; also another head, which is in a different cabinet, and is called a portrait of Raffaello; together with the half-length figure of a young nun so much commended by Bottari, and which he points out as one of the greatest treasures in the splendid mansion of the Marchese Niccolini. In the same rank we may include the much admired specimens in the possession of some of the noble families at Rome; as the picture of Christ disputing in the Temple, and the supposed portrait of queen Giovanna, ornamented with fine architecture, in the Doria palace; the Vanity and Modesty in the Barberini palace, the tints of which no pencil has been able to imitate; the Madonna of the Albani Palace, that appears to be requesting the lily which the infant Jesus holds in his hand, while he draws back, as if unwilling to part with it; a picture of exquisite grace, and preferred by Mengs to every other painting contained in that fine collection. It would, however, be presumptuous to assign a date to every picture of an artist who became early a distinguished painter, and who frequently discontinued a work before it was completed. When this celebrated artist had attained his sixty-third year, he appears to have renounced the art for ever. Francis I. who saw his Last Supper at Milan, about the year 1515, attempted to saw it from the wall, that it might be transported to France; and not succeeding in his project, was desirous of possessing the artist, though now an old man. He invited Vinci to his court, and the artist felt little regret at leaving Florence, where, since his return, he found in the young Bonarruoti a rival that had already contended with him, and was even employed in preference to Vinci both in Florence and in Rome; because the former gave them works, if we may credit Vasari, while the latter amused them with words.[134] It is known that they had a quarrel; and Lionardo consulting his repose, which their emulation embittered, passed over into France, where, before he had employed his pencil, he expired in the arms of Francis I., in the year 1519.
