But though originality of conception, the creation of imagery, and the invention of events belong to early ages, delicacy of taste, refinement of sentiment, perfection of expression, are the growth of a more advanced period of society. The characters which are delineated by the hand of Genius in early times, are those bold and original ones in which the features are distinctly marked, the lines clearly drawn, the peculiarities strongly brought out. The images which are adopted are those which have first occurred to the creative mind in forming a world of fancy: the similes employed, those which convey to the simple and unlettered mind the clearest or most vivid conception of the idea or event intended to be illustrated. Valour, pride, resolution, tenderness, patriotism, are the mental qualities which are there portrayed in imaginary characters, and called forth by fictitious events: and it is this first and noblest delineation of mental qualities in an historical gallery which has rendered the _Iliad_ immortal. The images and similes of Homer are drawn from a close observation of nature, but they are not very varied in their range: he paints every incident, every occurrence, every feature, but he is not much diversified in conception, and surprisingly identical in expression. His similes of a boar beset by hunters, of a lion prowling round a fold and repelled by the spear of the shepherd, of a panther leaping into a herd of cattle, are represented in the same words wherever he has a close fight of one of his heroes with a multitude of enemies to recount. So forcibly is the creative mind, in the first instance, fascinated by the variety and brilliancy of its conceptions, that it neglects and despises their subordinate details. It is careless of language, because it is intent on ideas: it is niggardly in language, because it is prodigal of thought. Homer's expressions or epithets are in general admirably chosen, and speak at once a graphic eye and an imaginative mind; but it is extraordinary how often they recur without any variation. It is the same with Ariosto: he is somewhat more varied in his expression, but even more identical in his details. Prodigal of invention, varied in imagination, unbounded in conception, in the incidents and great features of his story, he has very little diversity in its subordinate parts. He carries us over the whole earth, through the air, and to the moon: but giants, castles, knights, and errant damsels occur at every step, with hardly any alteration. The perpetual jousts of the knights, charging with the lance and then drawing the sword, are exactly parallel to the endless throwing of the spear and leaping from the chariot in the _Iliad_.
