Fanciful and unrealised is 'Watteau Painting,' with the following quotation from Du Fresnoy's Art of Painting.
'White, when it shines with unstained lustre clear,
May bear an object back, or bring it near.'
Turner was greatly interested in the theory of colour. He read and annotated Goethe's Theory of Colour, his copy of which is among the 'Relics' at the Tate Gallery.
The 'Watteau Painting' panel shows that artist, standing in the centre of the room, making a drawing of a lady and a gentleman reclining upon a divan. We have a glimpse of Turner's fun in the sketch he made at Petworth of himself, in the place of Watteau, painting in a room surrounded by some of the ladies of the household. I have nothing to say in favour of 'Lord Percy under Attainder,' except to remark that the dame in yellow is taken from a picture by Van Dyck at Petworth.
To this year belongs the golden 'Admiral Van Tromp's Barge at the Entrance of the Texel,' in the Soane Museum. Turner painted three or four Van Tromp pictures at different periods: one is in Sir Edward Tennant's collection, another is loaned by the nation to Sheffield, and a fourth, painted as late as 1844, is in the Royal Holloway College. All bear slightly different titles, and all are breezy and golden. Another picture of 1831, a fine, wild sea-piece, is in the Victoria and Albert Museum. The title is an apt description: 'Life Boat and Manby Apparatus going off to a Stranded Vessel making Signals (Blue Lights) of Distress.' The 'Sketch of Cochem on the Moselle' needs no description. It is a mere impression of light and movement, a quick record, unfinished if you like, yet quite finished in its statement of essential beauty.
Turner made a special journey to Scotland this year to make illustrations for Sir Walter's Scott Poetical and Prose Works. Turner was the guest of Sir Walter, and together they visited the most interesting spots on the Tweed and the Border, and in one of the plates—the Melrose—he, Scott and Cadell, small figures, are shown together, picnicking on a height overlooking the river and the Abbey.
On the 10th of June he signed his will, to be followed later by codicils, the vast, complicated will that he brooded over so long, that produced interminable litigation, with the result that almost all of his behests were disregarded. The Turner Gallery at Millbank is a magnificent, if tardy, reparation.
