As first suggested by Rodolfo Pallucchini in 1954 (op. cit.), this portrait of a young boy is identifiable with the disguised portrait in the figure of the music-making angel in Tintoretto’s Doge Alvise Mocenigo and Family before the Madonna and Child of circa 1575 (Washington, National Gallery of Art, inv. no. 1961.9.44). The features of the two figures are closely comparable, thus suggesting that the sitter was a member of the Mocenigo family. As such, Pallucchini argues that he was a grandson of Doge Giovanni Mocenigo (1409-1485) and the great nephew of Doge Alvise (1507-1577) in Tintoretto’s votive canvas. Rossi dates the present portrait to around 1575, and thus to the same moment as the Washington picture.
