Ulysses follows the direction of Circe, indeed he is propelled by the wind which she sends, to the "confines of the Ocean stream," to the limits of this terrestrial Upperworld. Here is the land of the Cimmerians, "hid in fog and in cloud," which veils the realm of the dead; here the sun sends no beam, either rising or setting. Again it is possible that the poet may have heard some dim account of the regions of the extreme North. But the significance of the Cimmerians is to shadow forth the dark border-land between life and death, which is here that between the limited and the unlimited. We see the strong attempt of the poet to get beyond limitation in its twofold appearance: first he will transcend the external boundary of the Homeric horizon, that of the sea stretching far to the westward; still more emphatic is his effort to transcend the limits of finite thinking and to reach an infinite realm, which is the goal of the spirit. He sweeps out of sensuous space, yet the poetic imagination has to remain in space after all, though it be a new space of its own creation. In like manner, he has to give the disembodied souls some finite nourishment in the shape of food and blood, in order that they become real. We feel in these dark Cimmerian limits his wrestle to pass over to the supersensible by thought.
I. The Present is represented by Ulysses and his companions, who now perform the rites consisting of a sacrifice and prayer to "the nations of the dead." We may find in the libation of "mingled honey, sweet wine, and water," a suggestion of the tissues and fluids of the body, while the blood of the sacrificed animals hints the principle of vitality. When the disembodied spirit tastes these elements, it gets a kind of body again, sufficient at least to be able to speak. That the sheep must be black is curiously symbolical, hinting the harmony expressed in the color of the animal and of Hades.
The souls "came thronging out of Erebus," eager to communicate. This aspiration must thus be their general condition; they wish to hear from us as much as we wish to hear from them. Hence there must be a selection, which involves a new rite, the flaying and the burning of the carcasses of the animals along with "prayer to Pluto and Proserpine" king and queen of the Underworld. Yet this choice requires activity from the hero, who has to draw his sword and keep off the crowd of spirits, till the right one comes, the Theban seer Tiresias.
