The deeds of the immortal gods were told and sung at every fireside in Greece; and among these hero-tales there was none more popular than the story of how Apollo built for Neptune the famous wall of Troy. Many musicians would have been glad to perform a similar service for the mere fame that it would bring them, but they feared that the attempt to imitate Apollo would only result in failure and ridicule. So no mortal ever presumed to say that he could make rocks and stones obedient to the spell of his music. There was, however, one musician, Amphion, king of Thebes, who was anxious to prove that his playing was equal to Apollo's, but knowing how unwise it was to vie with an immortal, he determined not to test his skill publicly, but to carry out his cherished plan at night, when men were dreaming in their beds. He was eager to build a high wall around Thebes, and to build it as Apollo did the wall of Troy; so when the sun set, and darkness crept over the earth, Amphion stood just outside the city gates and began to play on his lyre. Immediately the stones rose from the ground and moved rhythmically into their places in the wall, which soon rose strong and high--a firmer defense than any that could be built by men's hands.[28] Another famous musician was Arion, who won not only praise for his great skill in playing, but also much wealth. Whenever a contest was held in which a prize of money was given, Arion was usually a competitor; and, as his music was really finer than that of most players, he easily won the reward. Once he was returning from a festival in Sicily whither many musicians had gone on account of the rich prize; and as he had come off victor, he was leaving the foreign shores well-laden with gold. Unfortunately he happened to embark on a ship owned by pirates who had heard of his great wealth, and were plotting to seize whatever part of it he had on board. As the easiest way to do this was to kill him, the pirates began to bind him with ropes that he might not be able to struggle when thrown over-board. Arion calmly accepted his fate, but begged the brutal crew to allow him to play once upon his lyre before going to his death. To this the pirates consented, and when the wonderful music filled the air, a school of dolphins swam toward the ship and kept close beside it, charmed by Arion's playing. Feeling sure that there was some magic in the music, the pirates hastened to throw the player and his lyre into the sea without waiting to bind him; but Arion did not drown as they had expected, for a friendly dolphin caught him on its back and swam with him to the shore, where he landed in safety. When in the course of time Arion died, the gods placed him, together with his lyre and the kindly dolphin, in the sky as constellations.
