Homer, admirable in all respects, has the special merit of being the only poet who rightly appreciates the part he should take himself. The poet should speak as little as possible in his own person, for it is not this that makes him an imitator. Other poets appear themselves upon the scene throughout, and imitate but little and rarely. Homer, after a few prefatory words, at once brings in a man, or woman, or other personage; none of them wanting in characteristic qualities, but each with a character of his own.
The element of the wonderful is required in Tragedy. The irrational, on which the wonderful depends for its chief effects, has wider scope in Epic poetry, because there the person acting is not seen. Thus, the pursuit of Hector would be ludicrous if placed upon the stage—the Greeks standing still and not joining in the pursuit, and Achilles waving them back. But in the Epic poem the absurdity passes unnoticed. Now the wonderful is pleasing: as may be inferred from the fact that every one tells a story with some addition of his own, knowing that his hearers like it. It is Homer who has chiefly taught other poets the art of telling lies skilfully. The secret of it lies in a fallacy, For, assuming that if one thing is or becomes, a second is or becomes, men imagine that, if the second is, the first likewise is or becomes. But this is a false inference. Hence, where the first thing is untrue, it is quite unnecessary, provided the second be true, to add that the first is or has become. For the mind, knowing the second to be true, falsely infers the truth of the first. There is an example of this in the Bath Scene of the Odyssey.
Accordingly, the poet should prefer probable impossibilities to improbable possibilities. The tragic plot must not be composed of irrational parts. Everything irrational should, if possible, be excluded; or, at all events, it should lie outside the action of the play (as, in the Oedipus, the hero's ignorance as to the manner of Laius' death); not within the drama,—as in the Electra, the messenger's account of the Pythian games; or, as in the Mysians, the man who has come from Tegea to Mysia and is still speechless. The plea that otherwise the plot would have been ruined, is ridiculous; such a plot should not in the first instance be constructed. But once the irrational has been introduced and an air of likelihood imparted to it, we must accept it in spite of the absurdity. Take even the irrational incidents in the Odyssey, where Odysseus is left upon the shore of Ithaca. How intolerable even these might have been would be apparent if an inferior poet were to treat the subject. As it is, the absurdity is veiled by the poetic charm with which the poet invests it.
The diction should be elaborated in the pauses of the action, where there is no expression of character or thought. For, conversely, character and thought are merely obscured by a diction that is over brilliant.
With respect to critical difficulties and their solutions, the number and nature of the sources from which they may be drawn may be thus exhibited.
The poet being an imitator, like a painter or any other artist, must of necessity imitate one of three objects,—things as they were or are, things as they are said or thought to be, or things as they ought to be. The vehicle of expression is language,—either current terms or, it may be, rare words or metaphors. There are also many modifications of language, which we concede to the poets. Add to this, that the standard of correctness is not the same in poetry and politics, any more than in poetry and any other art. Within the art of poetry itself there are two kinds of faults, those which touch its essence, and those which are accidental. If a poet has chosen to imitate something, (but has imitated it incorrectly) through want of capacity, the error is inherent in the poetry. But if the failure is due to a wrong choice if he has represented a horse as throwing out both his off legs at once, or introduced technical inaccuracies in medicine, for example, or in any other art the error is not essential to the poetry. These are the points of view from which we should consider and answer the objections raised by the critics.
First as to matters which concern the poet's own art. If he describes the impossible, he is guilty of an error; but the error may be justified, if the end of the art be thereby attained (the end being that already mentioned), if, that is, the effect of this or any other part of the poem is thus rendered more striking. A case in point is the pursuit of Hector. If, however, the end might have been as well, or better, attained without violating the special rules of the poetic art, the error is not justified: for every kind of error should, if possible, be avoided.
Again, does the error touch the essentials of the poetic art, or some accident of it? For example,—not to know that a hind has no horns is a less serious matter than to paint it inartistically.
Further, if it be objected that the description is not true to fact, the poet may perhaps reply,—'But the objects are as they ought to be': just as Sophocles said that he drew men as they ought to be; Euripides, as they are. In this way the objection may be met. If, however, the representation be of neither kind, the poet may answer,—This is how men say the thing is.' This applies to tales about the gods. It may well be that these stories are not higher than fact nor yet true to fact: they are, very possibly, what Xenophanes says of them. But anyhow, 'this is what is said.' Again, a description may be no better than the fact: 'still, it was the fact'; as in the passage about the arms: 'Upright upon their butt-ends stood the spears.' This was the custom then, as it now is among the Illyrians.
Again, in examining whether what has been said or done by some one is poetically right or not, we must not look merely to the particular act or saying, and ask whether it is poetically good or bad. We must also consider by whom it is said or done, to whom, when, by what means, or for what end; whether, for instance, it be to secure a greater good, or avert a greater evil.
Other difficulties may be resolved by due regard to the usage of language. We may note a rare word, as in {omicron upsilon rho eta alpha sigma / mu epsilon nu / pi rho omega tau omicron nu}, where the poet perhaps employs {omicron upsilon rho eta alpha sigma} not in the sense of mules, but of sentinels. So, again, of Dolon: 'ill-favoured indeed he was to look upon.' It is not meant that his body was ill-shaped, but that his face was ugly; for the Cretans use the word {epsilon upsilon epsilon iota delta epsilon sigma}, 'well-favoured,' to denote a fair face. Again, {zeta omega rho omicron tau epsilon rho omicron nu / delta epsilon / kappa epsilon rho alpha iota epsilon}, 'mix the drink livelier,' does not mean `mix it stronger' as for hard drinkers, but 'mix it quicker.'
Sometimes an expression is metaphorical, as 'Now all gods and men were sleeping through the night,'—while at the same time the poet says: 'Often indeed as he turned his gaze to the Trojan plain, he marvelled at the sound of flutes and pipes.' 'All' is here used metaphorically for 'many,' all being a species of many. So in the verse,—'alone she hath no part...,' {omicron iota eta}, 'alone,' is metaphorical; for the best known may be called the only one.
