But it is in prose fiction that he really excels. He may claim to have, at least in the opinion of his contemporaries, invented a style, though perhaps the term _marivaudage_, which was applied to it, has a not altogether complimentary connotation. He may claim also to have invented the novel without a purpose, which aims simply at amusement, and at the same time does not seek to attain that end by buffoonery or by satire. Gray's definition of happiness, "to lie on a sofa and read endless novels by Marivaux" (it is true that he added Crebillon), is well known, and the production of mere pastime by means more or less harmless has since become so well-recognized a function of the novelist that Marivaux, as one of the earliest to discharge it, deserves notice. The name, however, of Jean Jacques Rousseau is of far different importance. His two great works, the _Nouvelle Heloise_ and _Emile_, are as far as possible from being perfect as novels. But no novels in the world have ever had such influence as these. To a great extent this influence was due mainly to their attractions as novels, imperfect though they may be in this character, but it was beyond dispute also owing to the doctrines which they contained, and which were exhibited in novel form. Such are the principal developments of fiction during the century; but it is remarkable that, varied as they were, and excellent as was some of the work to which they gave rise, none of these schools was directly very fertile in results or successors. The period with which we shall next have to deal, that from the outbreak of the Revolution to the death of Louis XVIII., is curiously barren of fiction of any merit. It was not till English influence began again to assert itself in the later days of the Restoration that the prose romance began once more to be written.
