"Such is the plan and the moral part of the Author's invention; the technic part, and the execution of the artist, though to be examined by other principles, and addressed to a narrower circle, equally claim approbation, sometimes excite our wonder, and not seldom our fears, when we see him play on the very verge of legitimate invention; but wildness so picturesque in itself, so often redeemed by taste, simplicity, and elegance, what child of fancy, what artist would wish to discharge? The groups and single figures on their own bases, abstracted from the general composition, and considered without attention to the plan, frequently exhibit those genuine and unaffected attitudes, those simple graces which Nature and the heart alone can dictate, and only an eye inspired by both, discover. Every class of artists, in every stage of their progress or attainments, from the student to the finished master, and from the contriver of ornament to the painter of history, will find here materials of art and hints of improvement!" This opinion he allowed Blake to publish as recommendatory of his work. In the early part of the year 1806, the Council of the Royal Academy requested that Fuseli would again deliver a course of lectures on painting, which he accordingly did, as Mr. Opie had not prepared his. This course he prefaced by the following address: "Gentlemen, "I once more have the unexpected honour of addressing you in this place, at the request of the President and Council, with the concurrence, and at the express desire of the Gentleman whom the Academy has appointed my successor, and whose superior ability, whenever he shall think proper to lay his materials before you, will, I trust, make ample amends for the defects which your indulgence has, for several years, connived at in my recital of these fragments on our art." Fuseli had now been more than two years Keeper of the Academy, which had afforded the students sufficient time to appreciate the value of his instructions, particularly in the antique school. And in order to mark their sense of the advantages which they had derived from his talents, they presented him, by the hands of Mr. Haydon, then a student, with an elegant silver Vase, the design for which, at their solicitation, was given by that eminent artist Flaxman; it bears the following inscription:-- TO HENRY FUSELI, ESQ. R.A. KEEPER OF THE ROYAL ACADEMY, FROM THE STUDENTS. 1807. The Vase, by the desire of Fuseli and the kindness of his widow, is now in my possession; and I not only value it as a beautiful work of art, but regard it as a tribute paid to the genius and talents of my honoured friend, whose memory will ever be held most dear in my recollection.
