Then saw he other females: Tyro, who when she lived was the paramour of Neptune, and by him had Pelias and Neleus. Antiope, who bore two like sons to Jove, Amphion and Zethus, founders of Thebes. Alcmena, the mother of Hercules, with her fair daughter, afterwards her daughter-in-law, Megara. There also Ulysses saw Jocasta, the unfortunate mother and wife of Oedipus; who, ignorant of kin, wedded with her son, and when she had discovered the unnatural alliance, for shame and grief hanged herself. He continued to drag a wretched life above the earth, haunted by the dreadful Furies. There was Leda, the wife of Tyndarus, the mother of the beautiful Helen, and of the two brave brothers Castor and Pollux, who obtained this grace from Jove, that, being dead, they should enjoy life alternately, living in pleasant places under the earth. For Pollux had prayed that his brother Castor, who was subject to death, as the son of Tyndarus, should partake of his own immortality, which he derived from an immortal sire. This the Fates denied; therefore Pollux was permitted to divide his immortality with his brother Castor, dying and living alternately. There was Iphimedia, who bore two sons to Neptune that were giants, Otus and Ephialtes: Earth in her prodigality never nourished bodies to such portentous size and beauty as these two children were of, except Orion. At nine years old they had imaginations of climbing to heaven to see what the gods were doing; they thought to make stairs of mountains, and were for piling Ossa upon Olympus, and setting Pelion upon that, and had perhaps performed it, if they had lived till they were striplings; but they were cut off by death in the infancy of their ambitious project. Phaedra was there, and Procris, and Ariadne, mournful for Theseus's desertion, and Maera, and Clymene, and Eryphile, who preferred gold before wedlock faith. But now came a mournful ghost, that late was Agamemnon, son of Atreus, the mighty leader of all the host of Greece and their confederate kings that warred against Troy. He came with the rest to sip a little of the blood at that uncomfortable banquet. Ulysses was moved with compassion to see him among them, and asked him what untimely fate had brought him there, if storms had overwhelmed him coming from Troy, or if he had perished in some mutiny by his own soldiers at a division of the prey. "By none of these," he replied, "did I come to my death; but slain at a banquet to which I was invited by Aegisthus after my return home. He conspiring with my adulterous wife, they laid a scheme for my destruction, training me forth to a banquet as an ox goes to the slaughter, and, there surrounding me, they slew me with all my friends about me.
