Through four or five centuries, by the hypothesis, every singer who could find an audience was treating as much as he knew of a vast body of ancient lays exactly as he pleased, adding here, lopping there, altering everywhere. Moreover, these were centuries full of change. The ancient Achaean palaces were becoming the ruins which we still behold. The old art had faded, and then fallen under the disaster of the Dorian conquest. A new art, or a recrudescence of earlier art, very crude and barbaric, had succeeded, and was beginning to acquire form and vitality. The very scene of life was altered: the new singers and listeners dwelt on the Eastern side of the Aegean. Knights no longer, as in Europe, fought from chariots: war was conducted by infantry, for the most part, with mounted auxiliaries. With the disappearance of the war chariot the huge Mycenaean shields had vanished or were very rarely used. The early vase painters do not, to my knowledge, represent heroes as fighting from war chariots. They had lost touch with that method. Fighting men now carried relatively small round bucklers, and iron was the metal chiefly employed for swords, spears, and arrow points. Would the new poets, in deference to tradition, abstain from mentioning cavalry, or small bucklers, or iron swords and spears? or would they avoid puzzling their hearers by speaking of obsolete and unfamiliar forms of tactics and of military equipment? Would they therefore sing of things familiar--of iron weapons, small round shields, hoplites, and cavalry? We shall see that confused and self-contradictory answers are given by criticism to all these questions by scholars who hold that the Epics are not the product of one, but of many ages. There were other changes between the ages of the original minstrel and of the late successors who are said to have busied themselves in adding to, mutilating, and altering his old poem. Kings and courts had passed away; old Ionian myths and religious usages, unknown to the Homeric poets, had come out into the light; commerce and pleasure and early philosophies were the chief concerns of life. Yet the poems continued to be aristocratic in manners; and, in religion and ritual, to be pure from recrudescences of savage poetry and superstition, though the Ionians "did not drop the more primitive phases of belief which had clung to them; these rose to the surface with the rest of the marvellous Ionic genius, and many an ancient survival was enshrined in the literature or mythology of Athens which had long passed out of all remembrance at Mycenas."
