From the brief geographical glances which we catch up from the voyage, as well as from a number of hints scattered throughout the Odyssey (for instance, from what is said of the Ethiopians in the First Book), we are inclined to believe that Homer held the earth to be round. We like to think of the old Poet seeing this fact, not as a deduction of science, not even as a misty tradition from some other land, but as an immediate act of poetic insight, which beholds the law of the physical world rising out of the spiritual by the original creative fiat; the Poet witnesses the necessity by which nature conforms to mind. Homer knew the spiritual Return, this whole Odyssey is such a Return, whereby the soul is rounded off to completeness, and becomes a true totality. Why should he not apply the same law to nature, to the whole Earth, and behold it, not indefinitely extended as it appears to the senses, but returning into itself, whereby the line becomes a circle and the plain a globe? Some such need lay deep in his poetic soul, to which he had to harmonize the entire universe, visible as well as invisible. Not science is this, but an immediate vision of the true, always prophetic, which observes the impress of spirit everywhere upon the realm of matter. The old Greek sages seem to have known not merely of the rotundity of the Earth, but also of its movement round the Sun and upon its own axis, both movements being circular, returns, which image mind. Did they get their knowledge from Egypt or Chaldea? Questionable; if they looked inwardly deep enough, they could find it all there. Indeed the sages of Egypt and Chaldea saw the fact in their souls ere they saw it or could see it in the skies. So these Homeric glimpses into the realm of what is to become science are not to be neglected or despised, in spite of their mythical, ambiguous vesture. Moreover they are in profound harmony with the present poem, to which they furnish remote, but very suggestive parallels, making the physical universe correspond to the spiritual unfolding of the Hero.
