In the year 1817, Fuseli sat, at my request, to Harlow for his portrait, which is on pannel, of a cabinet size. This eminent painter was highly gratified by the compliment, and exerted every faculty to do his best. Fuseli obliged him and me by giving for this picture twelve sittings of two hours each; and a more perfect resemblance, or characteristic portrait, has seldom been painted. I attended Fuseli at each sitting, and during the progress of this portrait. Harlow commenced and finished his best and most esteemed work, "The trial of Queen Katherine," in which he has introduced many portraits; but more particularly those of the Kemble family; in the performance of this work, he owed many obligations to Fuseli for his critical remarks; for when he first saw the picture (chiefly in dead colouring), he said, "I do not disapprove of the general arrangement of your work, and I see you will give it a powerful effect of light and shadow; but you have here a composition of more than twenty figures, or I should rather say parts of figures; because you have not shewn one leg or foot, which makes it very defective. Now, if you do not know how to draw legs and feet, I will shew you;" and taking up a crayon, drew two on the wainscot of the room. Harlow profited by these remarks, and the next time we saw the picture, the whole arrangement in the foreground was changed. Fuseli then said, "So far you have done well; but now you have not introduced a back figure, to throw the eye of the spectator into the picture;" and then pointed out by what means he might improve it in this particular. Accordingly Harlow introduced the two boys who are taking up the cushion; that which shews the back, is altogether due to Fuseli, and is certainly the best drawn figure in the picture. Fuseli afterwards attempted to get him to improve the drawing of the arms of the principal object (Mrs. Siddons), who is represented as Queen Katherine, but without much effect, particularly the left; and after having witnessed many ineffectual attempts of the painter to accomplish this, he desisted, and remarked, "It is pity that you never attended the Antique Academy."
