To proceed to the allegorical fable—If we reflect upon those innumerable knowledges, those secrets of nature and physical philosophy which Homer is generally supposed to have wrapped up in his allegories, what a new and ample scene of wonder may this consideration afford us! How fertile will that imagination appear, which as able to clothe all the properties of elements, the qualifications of the mind, the virtues and vices, in forms and persons, and to introduce them into actions agreeable to the nature of the things they shadowed! This is a field in which no succeeding poets could dispute with Homer, and whatever commendations have been allowed them on this head, are by no means for their invention in having enlarged his circle, but for their judgment in having contracted it. For when the mode of learning changed in the following ages, and science was delivered in a plainer manner, it then became as reasonable in the more modern poets to lay it aside, as it was in Homer to make use of it. And perhaps it was no unhappy circumstance for Virgil, that there was not in his time that demand upon him of so great an invention as might be capable of furnishing all those allegorical parts of a poem.
The marvellous fable includes whatever is supernatural, and especially the machines of the gods. If Homer was not the first who introduced the deities (as Herodotus imagines) into the religion of Greece, he seems the first who brought them into a system of machinery for poetry, and such a one as makes its greatest importance and dignity: for we find those authors who have been offended at the literal notion of the gods, constantly laying their accusation against Homer as the chief support of it. But whatever cause there might be to blame his machines in a philosophical or religious view, they are so perfect in the poetic, that mankind have been ever since contented to follow them: none have been able to enlarge the sphere of poetry beyond the limits he has set: every attempt of this nature has proved unsuccessful; and after all the various changes of times and religions, his gods continue to this day the gods of poetry.
We come now to the characters of his persons; and here we shall find no author has ever drawn so many, with so visible and surprising a variety, or given us such lively and affecting impressions of them. Every one has something so singularly his own, that no painter could have distinguished them more by their features, than the poet has by their manners. Nothing can be more exact than the distinctions he has observed in the different degrees of virtues and vices. The single quality of courage is wonderfully diversified in the several characters of the Iliad. That of Achilles is furious and intractable; that of Diomede forward, yet listening to advice, and subject to command; that of Ajax is heavy and self-confiding; of Hector, active and vigilant: the courage of Agamemnon is inspirited by love of empire and ambition; that of Menelaus mixed with softness and tenderness for his people: we find in Idomeneus a plain direct soldier; in Sarpedon a gallant and generous one. Nor is this judicious and astonishing diversity to be found only in the principal quality which constitutes the main of each character, but even in the under parts of it, to which he takes care to give a tincture of that principal one. For example: the main characters of Ulysses and Nestor consist in wisdom; and they are distinct in this, that the wisdom of one is artificial and various, of the other natural, open, and regular. But they have, besides, characters of courage; and this quality also takes a different turn in each from the difference of his prudence; for one in the war depends still upon caution, the other upon experience. It would be endless to produce instances of these kinds. The characters of Virgil are far from striking us in this open manner; they lie, in a great degree, hidden and undistinguished; and, where they are marked most evidently affect us not in proportion to those of Homer. His characters of valour are much alike; even that of Turnus seems no way peculiar, but, as it is, in a superior degree; and we see nothing that differences the courage of Mnestheus from that of Sergestus, Cloanthus, or the rest, In like manner it may be remarked of Statius’s heroes, that an air of impetuosity runs through them all; the same horrid and savage courage appears in his Capaneus, Tydeus, Hippomedon, &c. They have a parity of character, which makes them seem brothers of one family. I believe when the reader is led into this tract of reflection, if he will pursue it through the epic and tragic writers, he will be convinced how infinitely superior, in this point, the invention of Homer was to that of all others.
