This view was copied from a watercolour by the eighteenth-century English landscape painter John Robert Cozens. Turner reversed the composition but remained faithful to Cozens's tonal scheme and his treatment of foliage. Cozens had been a patient of Dr Monro, who greatly admired his watercolours. Turner probably made his copy as a student of Monro's informal evening 'Academy' (1794-1797), where he and fellow students could practice their watercolour skills making copies from works in Monro's collection. Cozens' watercolour of Lake Albano is in the City Art Gallery, Leeds.
