At MP I:156 Ruskin is critical of the colour of the leaves of Salvator Rosa 's trees. At MP I:384 he sees Salvator Rosa as providing the 'most gross examples' of 'total ignorance of tree structure'. The theme continues in Modern Painters V where Ruskin summarises the 'rude fallacies' ( Works, 7.68) of the trees of Salvator Rosa and Claude, and cites Salvator Rosa's choice of a withered tree as evidence of his 'preferring ugliness to beauty'( Works, 7.89), a reference to Ruskin's later judgements of Rosa's moral character. All of this is a challenge to Rosa's reputation for truth in his painting of nature.
