The reference to Titian on this page suggests that he was one of the painters Ruskin had in mind here. At MP I:107 Ruskin appears to include Titian, Veronese, and Tintoretto in the 'great group of Venetian painters'. Other Venetian painters mentioned in Modern Painters I include Giovanni Bellini, Gentile Bellini, Giorgione, Carpaccio, and Cima da Conegliano. However, they either are, or could have been, included with those who were described by William Dyce in 1853 as representing the 'adolescence' rather than the 'manhood' of painting (quoted in Haskell, Rediscoveries in Art, p.104). Ruskin's account of Canaletto is such that he is unlikely to be included in the 'great group'
