There is an intimate relation then between the artist and his work, and, rightly interpreted, the latter can tell us much about the former. Let us turn to Giorgione's work. Here we are brought face to face with an initial difficulty, the great difficulty, in fact, which has stood so much in the way of a more comprehensive understanding of the master, I mean, that scarcely anything of his work is authenticated. Three pictures alone have never been called in question by contending critics; outside this inner ring is more or less debatable ground, and on this wider arena the battle has raged until scarcely a shred of the painter's work has emerged unscathed. The result has been to reduce the figure of Giorgione to a shadowy myth, whose very existence, at the present rate at which negative criticism progresses, will assuredly be called in question. If Bacon wrote Shakespeare, then Giorgione can be divided up between a dozen Venetian artists, who "painted Giorgione." Fortunately three pictures survive which refuse to be fitted in anywhere else except under "Giorgione." This is the irreducible minimum, [Greek: _o anankaiotatos_] Giorgione, with which we must start. * * * * * Of the three universally accepted pictures, first and foremost comes the Castelfranco altar-piece, according to Mr. Ruskin "one of the two most perfect pictures in existence; alone in the world as an imaginative representation of Christianity, with a monk and a soldier on either side ... "[11] This great picture was painted before 1504, when the artist was only twenty-seven years of age,[12] a fact which clearly proves that his genius must have developed early. For not even a Giorgione can produce such a masterpiece without a long antecedent course of training and accomplishment. This is not the place to inquire into the nature and character of the works which lead up to this altar-piece, for a chronological survey ought to follow, not precede, an examination of all available material; it is important, nevertheless, to bear in mind that quite ten years had been passed in active work ere Giorgione produced this masterpiece.
