Boit returned to England in 1704, and was to continue in his path of success for a few more years. Walpole (who does not mention the excursion to the continent) remarks that Boit's prices "are not to be believed". He is said to have been paid 30 guineas for a copy of Godfrey Kneller's portrait of Colonel John Seymour, "for a lady's head, not larger, double that sum, and for a few plates 500 "l"." "If this appears enormous", writes Walpole, introducing his next example of Boit's extraordinary prices, "what will the reader think of the following anecdote?" This enamel, which was to be even larger than the one of the Imperial family, concerned a commission on which he worked for many years on behalf of Queen Anne and Prince George, an allegory over the victory at Blenheim.
