Crowe and Cavalcaselle. Titian, ii. 409.
There is a collection of these in a volume in the British Museum.
Before the discovery of the letter to Philip, Messrs. Crowe and Cavalcaselle were quite prepared to admit that Titian was born "after 1480" (vide N. Italian Painting, ii. 119, 120). Unfortunately, they took the evidence of the letter as final, but finding themselves chronologically in difficulties, they shrewdly remark in their Titian, i. 38, note: "The writers of these lines thought, and still think, Titian younger than either Giorgione or Palma. They were, however, inclined to transpose Titian's birthday to a later date than 1477, rather than put back those of Palma and Giorgione to an earlier period, and in this they made a mistake." Perhaps they were not so far wrong after all!
