The documents quoted by Signor Venturi show the signature was there in 1640.
When in the Martinengo Gallery at Brescia (1640) it bore this name. See Venturi, op. cit., and Crowe and Cavalcaselle, Titian, ii. 58.
From Das Museum, No. 79. "Unbekannter Meister um 1500. Bildnis der Caterina Cornaro." I am informed the original is now in the possession of the German Ambassador at The Hague, and that a plaster cast is at Berlin.
Dr. Bode (Jahrbuch, 1883, p. 144) says that Count Pourtalès acquired this bust at Asolo.
