The famous Tribuna is supposed to contain the masterpieces of the whole collection, though the lover of the Quattrocento will naturally seek his best-loved favourites elsewhere. Of the five ancient sculptures in the centre of the hall the best is that of the crouching barbarian slave, who is preparing his knife to flay Marsyas. It is a fine work of the Pergamene school. The celebrated Venus dei Medici is a typical Græco-Roman work, the inscription at its base being a comparatively modern forgery. It was formerly absurdly overpraised, and is in consequence perhaps too much depreciated at the present day. The remaining three--the Satyr, the Wrestlers, and the young Apollo--have each been largely and freely restored. Turning to the pictures, we have first the Madonna del Cardellino (1129), painted by Raphael during his Florentine period when under the influence of Fra Bartolommeo, in 1506 or thereabouts, and afterwards much damaged and restored: still one of the most beautiful of his early Madonnas. The St. John the Baptist (1127), ascribed to Raphael, is only a school piece, though from a design of the master's. The Madonna del Pozzo (1125), in spite of its hard and over-smooth colouring, was at one time attributed to Raphael; its ascription to Francia Bigio is somewhat conjectural. The portrait of a Lady wearing a wreath (1123), and popularly called the Fornarina, originally ascribed to Giorgione and later to Raphael, is believed to be by Sebastiano del Piombo. Then come a lady's portrait, ascribed to Raphael (1120); another by a Veronese master, erroneously ascribed to Mantegna, and erroneously said to represent the Duchess Elizabeth of Urbino (1121); Bernardino Luini's Daughter of Herodias (1135), a fine study of a female Italian criminal of the Renaissance; Perugino's portrait of Francesco delle Opere, holding a scroll inscribed _Timete Deum_, an admirable picture painted in oils about the year 1494, and formerly supposed to be a portrait of Perugino by himself (287); portrait of Evangelista Scappa, ascribed to Francia (1124); and a portrait of a man, by Sebastiano del Piombo (3458). Raphael's Pope Julius II. (1131) is a grand and terrible portrait of the tremendous warrior Pontiff, whom the Romans called a second Mars. Vasari says that in this picture he looks so exactly like himself that "one trembles before him as if he were still alive." Albert Dürer's Adoration of the Magi (1141) and Lucas van Leyden's Mystery of the Passion (1143) are powerful examples of the religious painting of the North, that loved beauty less for its own sake than did the Italians. The latter should be compared with similar pictures by Don Lorenzo and Fra Angelico. Titian's portrait of the Papal Nuncio Beccadelli (1116), painted in 1552, although a decidedly fine work, has been rather overpraised.
