In a letter to the Duke of Mantua, from Bologna, 10 March 1533; as quoted by J.A.Y. Crowe & G.B. Cavalcaselle in Titian his life and times - With some account..., publisher John Murray, London, 1877, p. 370
The portrait which Titian took home and repeated a second time he doubtless sent to Charles V. The replica was not sent to Mantua till after 1536, but there it appears to have remained. Another example besides that of the Madrid Museum came into the hands of Charles the First of England.
1510-1540
