Quote from a letter of Titian, to the Marquess Gonzaga of Mantua, from Venice 22 Juin 1527; 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. 317
Assuredly Titian at this time had Messer Pietro Aretino for a sitter; this letter proves his intimacy with the secretary of Giovanni de Medici
1510-1540
