The gold medal of the year has been courteously bestowed upon Mr. Martin for his picture of the Deluge. Had I been the judge, I should have awarded it to Stuben's Battle of Waterloo. That the faculty of imagination is one of the highest requisites for a painter is most certain; and that Mr. Martin pre-eminently possesses it, not less so. But imagination, though it can do much, cannot do all; and common sense is at least equally important in the formation of a finished artist. The painter of the great day of Waterloo has both. His imagination has enabled him to dive into the very hearts and souls of the persons he has depicted. Passion speaks in every line; and common sense has taught him, that, however powerful--nay, vehement, might be the expression he sought to produce, it must be obtained rather by the patient and faithful imitation of Nature than by a bold defiance of her. The Assassination of the Duc de Guise, by M. Delaroche, is an admirable and highly popular work. It requires some patient perseverance to contest inch by inch the slow approach to the place where this exquisite piece of finishing is hung--but it well rewards the time and labour. One or two lovely little pictures by Franquelin made me envy those who have power to purchase, and sigh to think that they will probably go into private collections, where I shall never see them more. There are, indeed, many pictures so very good, that I think it possible the judges may have relieved themselves from the embarrassment of declaring which was best, by politely awarding the palm to the stranger. I could indulge myself, did I not fear to weary you, by dwelling much longer upon my agreeable recollections of this extensive exhibition--containing, by the way, 2,174 pictures,--and might particularise many very admirable works. Nevertheless, I must repeat, that thus hiding the precious labours of all schools, and of all ages of painting, by the promiscuous productions of the living artists of France during the last year, is a most injudicious device for winning for them the golden opinions of those who throng from all quarters of the world to visit the Louvre. This exhibition reaches to about three-fourths of the gallery; and where it ceases, a grim curtain, suspended across it, conceals the precious labours of the Spanish and Italian schools, which occupy the farther end. Can anything be imagined more tantalising than this? And where is the living artist who could stand his ground against such cruel odds? To render the effect more striking still, this dismal curtain is permitted so to hang as to leave a few inches between its envious amplitude and the rich wall--suffering the mellow browns of a well-known Murillo to meet and mock the eye. Certainly not all the lecturers of all the academies extant could point out a more effectual manner of showing the modern French artist wherein he chiefly fails: let us hope he will profit by it.
