Nearly all the Venetian pictures were bought in 1654 by Cardinal Leopoldo de' Medici from Messer Paolo del Sera, a Florentine merchant in Venice. More truly representative of the Renaissance, its humanism and splendour, than any other school of painting in Italy, the earlier works of that great Venetian School are not seen to advantage in the Uffizi. There is nothing here by Jacopo Bellini, nothing by his son Gentile; nor any work from the hands of Antonio or Bartolommeo Vivarini, or Antonello da Messina, who apparently introduced oil painting into Venice. It is not till we come to Giovanni Bellini, born about 1430, that we find a work of the Quattrocento in the delightful but puzzling Allegory (631), where Our Lady sits enthroned beside a lagoon in a strange and lovely landscape of rocks and trees; while beside her kneels St. Catherine of Alexandria, and again, St. Catherine of Siena; farther away stand St. Peter and St. Paul, while below children are playing with fruit and a curious tree; on the other side are Job and St. Sebastian, while in the background you may see the story of the life of St. Anthony. This mysterious picture certainly stands alone in Giovanni Bellini's work, and suggests the thoughts at least of Mantegna; and while it is true that Giovanni had worked at Padua, one is surprised to come upon its influence so late in his life.[125] The influence of the Bellini is to be found in almost all the great painters of Venice in the Cinquecento. We come upon it first in the work of Vittore Carpaccio, of which there is but a fragment here, the delicate little picture, the Finding of the True Cross (583 _bis_); while in two works attributed to Bissolo and Cima da Conegliano (584, 564 _bis_), we see too the influence of Bellini.
