What may legitimately excite surprise in the beginnings both of Giorgione and Titian, so far as they are at present ascertained, is not so much that in their earliest productions they to a certain extent lean on Giovanni Bellini, as that they are so soon themselves. Neither of them is in any extant work seen to stand in the same absolutely dependent relation to the veteran Quattrocentist which Raphael for a time held towards Perugino, which Sebastiano Luciani in his earliest manhood held towards Giorgione. This holds good to a certain extent also of Lorenzo Lotto, who, in the earliest known examples--the so-called _Danaë_ of Sir Martin Conway's collection, and the _St. Jerome_ of the Louvre--is already emphatically Lotto, though, as his art passes through successive developments, he will still show himself open to more or less enduring influences from the one side and the other. Sebastiano del Piombo, on the other hand, great master as he must undoubtedly be accounted in every successive phase, is never throughout his career out of leading-strings. First, as a boy, he paints the puzzling _Pietà_ in the Layard Collection at Venice, which, notwithstanding the authentic inscription, "Bastian Luciani fuit descipulus Johannes Bellinus (sic)," is so astonishingly like a Cima that, without this piece of documentary evidence, it would even now pass as such. Next, he becomes the most accomplished exponent of the Giorgionesque manner, save perhaps Titian himself. Then, migrating to Rome, he produces, in a quasi-Raphaelesque style still strongly tinged with the Giorgionesque, that series of superb portraits which, under the name of Sanzio, have acquired a world-wide fame. Finally, surrendering himself body and soul to Michelangelo, and only unconsciously, from the force of early training and association, allowing his Venetian origin to reveal itself, he remains enslaved by the tremendous genius of the Florentine to the very end of his career. Giorgione and Titian were as nearly as possible of the same age, being both of them born in or about 1477. Lorenzo Lotto's birth is to be placed about the year 1476--or, as others would have it, 1480. Palma saw the light about 1480, Pordenone in 1483, Sebastiano Luciani in 1485. So that most of the great protagonists of Venetian art during the earlier half of the Cinquecento were born within the short period of eight years--between 1477 and 1485.
