The word Hero is one of those Greek words which have been adopted into all European languages, because they signify precisely a universal idea of the thing. He must be strong and able in battle, for a lost fight might mean the death or slavery of all his people. If the hero does his living and dying in a noble fashion, the folk trouble themselves very moderately about minor questions of religion or ethics, and are very moderately scandalised by occasional ferocity. Such a man is not to be hampered by ordinary rules; he is like a general commanding in the field, who may do anything for the preservation of his army, and the consequence is that he is seldom expected to moralise. He acknowledges and pays great honour to the cardinal virtues of truth-speaking, mutual fidelity, hospitality, strict observance of pledges. He is in many ways a religious man; though he is apt to break away from the priests when they interfere seriously with the business in hand. For the chastity of wives he has a high esteem, yet although he and his people are constantly brought into trouble about women, he is tolerant of them, even when their behaviour is what might be called regrettable; he treats them in some degree as irresponsible beings, on the ground, perhaps, that they are the only non-combatants in the world as he knows it, and that this gives them special privileges. We can measure the importance of such a personage in ancient days, by the noise which a first-class hero made in the primitive world. He became literally and figuratively immortal: he was regarded as a god, or at least godlike--the greatest of them were actually deified. He was seized upon by fable, myth, miraculous legend, and poetry--his name was handed down for centuries until the heroic lineaments were softened down, disfigured, and at last faded away in the magical haze of later Romance. But in very rare instances he had the good luck to be taken in hand, before it was too late, by some man of genius, who knew the temper of heroic times because he lived within range of them, and who has preserved for us a story, an incident, or a typical character--not, indeed, an authentic narrative, for the true story disappears under the tradition which is built over it; nor would such accurate knowledge be of much use to the poet, whose business it is only to give us a fine spirited account of what might have occurred. For the evidence that an ancient battle was really fought we must go to the historian; the poet will tell us how it was fought, he stirs the blood and fires the imagination by his tale of noble deeds and deaths. His strength rests upon the foundation of reality that underlies his artistic construction: he has never let go his hold upon sound experience: and the truth is felt in all the colour and detail of the picture, though the whole is a work of vivid imagination. We cannot verify, obviously, the facts and motives which led to the siege of Troy, although Herodotus appears to agree that the cause of that war was a Spartan woman's abduction, and only examines the point whether the Asiatic or the European Greeks were first to blame in the matter. Professor Murray prefers to believe in a myth growing out of the strife of light and darkness in the sky: but the rape of beautiful girls by seafaring rovers was evidently common enough in those times, so why should not the Homeric version be right? We can always be sure that the old poems represent accurately life, manners, and character; and from the analogy of those legends whose origin is known, we may fairly infer that the root of a famous story, divine or human, is first planted in fact, not in fancy; just as the Chanson de Roland is founded on a real battle in the pass of Roncevalles.
