Nestor, therefore, cannot tell much about Ulysses, who lies quite out of his horizon, at least in the Odyssey. He can only give hope that the man of wisdom will yet return. This Telemachus doubts, dropping into one of his low human moods, even in the presence of Pallas, who rebukes him sharply. It is, indeed, the great lesson; he must have faith in the reality of the Gods, this is the basis of all his future progress, the chief attainment of wisdom. The young man must not fall away into denial, he must be taught that there is a divine order in the world. Old Homer, too, had his notions about religion in education, and the Goddess herself is here introduced giving a lesson. Nestor, though unable himself to give much information about the Return, can point to the second grand Returner, Menelaus, who has lately come from a distant land, and may have something to say. In fact Menelaus was the last to separate from Nestor, Ulysses had separated long before. One other story Nestor tells with great sympathy, that of Agamemnon, who represents a still different form of the Return. The great leader of the Greeks can master the Trojan difficulty, can even get back to home and country, but these are ultimately lost to him by his faithless spouse. Still, after the father's death, the son Orestes restores Family and State. Therein Telemachus sees an image of himself, the son, who is to slay his mother's suitors; he sees, too, the possible fate of his father. Ulysses has essentially the same problem as Agamemnon, though he has not the faithless wife in addition; Telemachus beholds his duty in the deed of Orestes, according to Greek consciousness. We shall see hereafter how Ulysses takes due precaution not to be slain in his own land, as Agamemnon was. In disguise he will go to his own palace and carefully note the situation in advance, and then strike the blow of deliverance. Several times Homer repeats in the Odyssey the tragic story of Agamemnon, the great Leader of the Greeks at Troy. An awe-inspiring tale of destiny; out of it AEschylus will develop his great tragedy, the Oresteia. Indeed the epos develops into tragedy with the full mythical unfolding of this story. AEschylus will deepen the motives into internal collisions; he will show the right and the wrong in Agamemnon, and even in Clytemnestra. Orestes, however beneficent his deed in avenging his father, will not escape the counterstroke; AEschylus will send after him the Furies for the guilt of having murdered his mother. Thus the double nature of the deed, its reward and its penalty, unfolds out of Homer into AEschylus, and creates the Greek drama as we know it at present.
