The moment that is depicted in the oil painting, and presumably the composition study and present sketch, is when the King was presented with a silver basin of rose water to wash his hands by William Howison Craufurd attended by Walter Scott’s son, Charles, and his nephew Walter (see Tate D34946
; Turner Bequest CCCXLIV d 446).6
Beneath the sketch are four figures studies. The top-left of these is recognisable as George IV, ‘who was dressed in a field-marshal’s uniform’,7
and whose haircut is quite distinctive and recognisable from the oil painting. A sketch on Tate D34943
(Turner Bequest CCCXLIV d 443) may also depict George IV. Beneath him is a figure with a dark collar that is recognisable at the centre of the group above. His uniform suggests that he is perhaps the Lord Provost, Sir William Arbuthnot, or perhaps the Reverend Baird.8
To his right is a moustachioed figure in military uniform, perhaps someone like the Duke of Hamilton (Alexander Douglas Hamilton). To the right of the King is a wigged figure, perhaps Craufurd who is shown kneeling and wearing such a wig in the oil painting. To the left of the King Turner has sketched a figure’s hair only. This may have been an abandoned sketch of King George. Further figure studies made at the banquet are on Tate D34943
(Turner Bequest CCCXLIV d 443).
