Myths and Legends of Ancient Greece and Rome
Eos first married the Titan Astræus, and their children were Heosphorus (Hesperus), the evening star, and the winds. She afterwards became united to Tithonus, son of Laomedon, king of Troy, who had won her affection by his unrivalled beauty; and Eos, unhappy at the thought of their being ever separated by death, obtained for him from Zeus the gift of immortality, forgetting, however, to add to it that of eternal youth. The consequence was that when, in the course of time, Tithonus grew old and decrepid, and lost all the beauty which had won her admiration, Eos became disgusted with his infirmities, and at last shut him up in a chamber, where soon little else was left of him but his voice, which had now sunk into a weak, feeble quaver. According to some of the later poets, he became so weary of his cheerless and miserable existence, that he entreated to be allowed to die. This was, however, impossible; but Eos, pitying his unhappy condition, exerted her divine power, and changed him into a grasshopper, which is, as it were, all voice, and whose monotonous, ceaseless chirpings may not inaptly be compared to the meaningless babble of extreme old age.
