First of all, there must be felt and seen the necessity of taking this journey to the Netherworld on the part of the Hero, the complete person of his time. The very conception of the universal man must include the visit to the realm of the Idea; the passage from the sensible to the supersensible, is the deepest need of his soul. Homer can give this spiritual movement only in a mythical form, hence it occurs here in Fableland. So Ulysses has to make the transition from Circe to Hades. Having the entire Book now before us, we observe that it shows a threefold movement; that is, one movement with three leading stages. These take the shape of three communications from the realm of the dead, which includes all past Time, imparted to the living who are now present, namely the Phaeacians, through Ulysses, who has had this cycle of experiences and now sings them. But that which is true in past Time must be seen to be true in all Time--Past, Present and Future. So there unfolds the idea of a World-Order, foretold at first by the Pre-Trojan prophet Tiresias, illustrated by the fate of the three Greco-Trojan heroes in Hades, and finally realized and active in the realm of Minos. The whole has, therefore, the secret underlying thought of a world-tribunal, which works through all human history; it is a kind of Last Judgment to which the deeds of men are appealed for final adjudication; it most profoundly suggests in its movement the ethical order of the Universe. Let us briefly sum up its three stages. I. The first communication from the Hades of the Past to the real world of the Present through Ulysses is that of the prophet Tiresias, "whose mind is whole;" he may be called the pure Idea (as subjective) uttering the Idea (as objective, as principle of the world). For he beholds the truth of things as they are in their essence, he himself being the impersonation of Truth. Thus he looks through the Future and foretells; he knows that Neptune will avenge the deed done to Polyphemus, that the Oxen of the Sun constitute a great danger, that Ulysses will punish the Suitors; then he prophesies the peace and final harmony of Ulysses after his long conflict and separation from home, country, and the Divine Order. So speaks Tiresias and is therein a kind of world-judge, prefiguring Minos of the last stage of Hades. For he prophesies according to the law of the deed; what you have done is sure to return upon you, be it good or bad. Hence he can tell what will happen to Ulysses for acts already committed (the wrath of Neptune); he can give a warning concerning things which Ulysses may do (the slaying of the Oxen of the Sun); he can affirm the certain punishment of guilt (the case of the Suitors). Thus the prophet voices a world-justice, which inflicts the penalty unflinchingly, but also bears within itself reconciliation. Such is the prophetic Idea, appearing in advance, not yet ordered and realized.
