What caricature is in painting, burlesque is in writing; and in the same manner the comic writer and painter correlate to each other; as in the former, the painter seems to have the advantage, so it is in the latter infinitely on the side of the writer. For the monstrous is much easier to paint than describe, and the ridiculous to describe than paint.
