Christopher Le Brun on Turner

'I find him the most open of painters. The transparency of his light is an everpresent sign of how he achieves complete fluency of memory and reference. In the same painting he can move with ease from the observation of the humble disorderliness of everyday life to the remotest imaginary scenes of theatrical mythology.

Space in Turner is always dense with thought and feeling: It is visible thought. Has there ever been another painter with such a range and depth of pictorial space?'
