XXXVII The story of the true and false Dreams and the horn and ivory gates rests on a double play of words: ἐλέφας (elephas), ivory, and ἐλεφαιρομαι (elephairomai), to cheat with false hope; κερας (keras), horn, and κραίνειν (krainein), to fulfill. Poem:-- The Ivory Gate MORTIMER COLLINS Dreams were sometimes sent through the gates of horn to prepare mortals for misfortunes, as was the case of Halcyone. Ceÿx, king of Thessaly, once left his beloved wife, Halcyone, to go on a journey to the oracle of Delphi. On the outgoing voyage, a tempest struck the ship on which the king was sailing, and he with all his crew perished in the waves. Every day the queen went down to the seashore to watch for the returning vessel, and every night she prayed to the gods to bring her husband safely back to her. Juno, knowing that these prayers were in vain, pitied the faithful Halcyone, and wished to prepare her for the great sorrow that must soon come with the news of Ceÿx's death. So she sent Iris to the cave of sleep, and the rainbow goddess bade one of the Dreams go forth from the gate of horn to visit the sleeping queen. The Dream glided to Halcyone's bedside, and, assuming the form of Ceÿx, appeared before her pale, like a dead man, and dripping with the salt sea. He told his wife that the storm had sunk his ship, and that he himself was dead. Terrified at this vision, Halcyone sprang from her couch and hastened to the beach, where she found the body of her husband washed up by the waves. In pity for her grief, the gods changed both Halcyone and Ceÿx into birds that ever afterward lived on the waters, and were known as the Halcyon birds. These birds uttered shrill cries of warning to all seamen whenever a storm threatened, but were themselves so fearless of the sea that they built their nests and hatched their young on the ever-tossing waves. XXXVIII The Nereides trained Arion, the wonderful winged steed that had the power of speech, to draw his father's chariot over the waves. He was said to be the first and the fleetest of horses, and passed successively into the hands of Cepreus (Pelops' son), Hercules, and Adrastus--the last of whom won all the chariot races, thanks to the fleetness of Arion. Neptune was a patron of horse trainers, and was himself especially devoted to horses.
