“The excursus upon the origin of Odysseus’ scar is not basically different from the many passages in which a newly introduced character, or even a newly appearing object or implement, though it be in the thick of a battle, is described as to its nature and origin; or in which, upon the appearance of a god, we are told where he last was, what he was doing there, and by what road he reached the scene; indeed, even the Homeric epithets seem to me in the final analysis to be traceable to the same need for an externalization of phenomena in terms perceptible to the senses. Here is the scar, which comes up in the course of the narrative; and Homer’s feeling simply will not permit him to see it appear out of the darkness of an unilluminated past; it must be set in full light, and with it a portion of the hero’s boyhood. … To be sure, the aesthetic effect thus produced was soon noticed and thereafter consciously sought; but the more original cause must have lain in the basic impulse of the Homeric style: to represent phenomena in a fully externalized form, visible and palpable in all their parts, and completely fixed in their spatial and temporal relations. Nor do psychological processes receive any other treatment: here too nothing must remain hidden and unexpressed. With the utmost fullness, with an orderliness which even passion does not disturb, Homer’s personages vent their inmost hearts in speech; what they do not say to others, they speak in their own minds, so that the reader is informed of it. Much that is terrible takes place in the Homeric poems, but it seldom takes place wordlessly: Polyphemus talks to Odysseus; Odysseus talks to the suitors when he begins to kill them; Hector and Achilles talk at length, before battle and after; and no speech is so filled with anger or scorn that the particles which express logical and grammatical connections are lacking or out of place.”
