It is somewhat difficult to find a common measure for these names, but it is clear that what is most distasteful to the writer, in theory at any rate, is variety. Epic is the most solemn, stately, and frigid of all kinds of composition. This was the result attained by the perverse following of precepts supposed to be classical. The critics of the seventeenth and eighteenth centuries were generally right in distinguishing between Epic and Romance, and generally wrong in separating the one kind from the other as opposite and mutually exclusive forms, instead of seeing with Tasso, in his critical discourses, that romance may be included in epic. Against the manifold perils of the Gothic fantasy they set up the image of the Abstract Hero, and recited the formulas of the decorous and symmetrical abstract heroic poem. They were occasionally troubled by the "Gothic" elements in Homer, of which their adversaries were not slow to take advantage. One of the most orthodox of all the formalists, who for some reason came to be very much quoted in England, Bossu, in his discourse on the Epic Poem, had serious difficulties with the adventures of Ulysses, and his stories told in Phaeacia. The episodes of Circe, of the Sirens, and of Polyphemus, are _machines_; they are also not quite easy to understand. "They are necessary to the action, and yet they are not humanly probable." But see how Homer gets over the difficulty and brings back these _machines_ to the region of human probability. "Homère les fait adroitement rentrer dans la Vraisemblance humaine par la simplicité de ceux devant qui il fait faire ses récits fabuleux. Il dit assez plaisamment que les Phéaques habitoient dans une Isle éloignée des lieux où demeurent les hommes qui ont de l'esprit. [Greek: heisen d' en Scheriê hekas andrôn alphêstaôn]. Ulysses les avoit connus avant que de se faire connoître à eux: et aiant observé qu'ils avoient toutes les qualités de ces fainéans qui n'admirent rien avec plus de plaisir que les aventures Romanesques: il les satisfait par ces récits accommodez à leur humeur. Mais le Poëte n'y a pas oublié les Lecteurs raisonnables. Il leur a donné en ces Fables tout le plaisir que l'on peut tirer des véritez Morales, si agréablement déguisées sous ces miraculeuses allégories. C'est ainsi qu'il a réduit ces Machines dans la vérité et dans la Vraisemblance Poëtique."[7] [Footnote 7: _Traité du Poëme Épique_, par le R.P.
