Then she advised them of all the dangers of their way home to Greece, how they must shun the Sirens, and Scylla and Charybdis, and she sent a messenger, Iris, the goddess of the Rainbow, to bid Thetis help them through the perils of the sea, and bring them safe to Phæacia, where the Phæacians would send them home. 'But you shall never be happy, nor know one good year in all your lives,' said Circe, and she bade them farewell. They went by the way that Ulysses went on a later day; they passed through many perils, and came to Iolcos, where Pelias was old, and made Jason reign in his stead. But Jason and Medea loved each other no longer, and many stories, all different from each other, are told concerning evil deeds that they wrought, and certainly they left each other, and Jason took another wife, and Medea went to Athens. Here she lived in the palace of Ægeus, an unhappy king who had been untrue to his own true love, and therefore the gods took from him courage and strength. But about Medea at Athens the story is told in the next tale, the tale of Theseus, Ægeus's son. THESEUS I THE WEDDING OF ÆTHRA Long before Ulysses was born, there lived in Athens a young king, strong, brave, and beautiful, named Ægeus. Athens, which later became so great and famous, was then but a little town, perched on the top of a cliff which rises out of the plain, two or three miles from the sea. No doubt the place was chosen so as to be safe against pirates, who then used to roam all about the seas, plundering merchant ships, robbing cities, and carrying away men, women, and children, to sell as slaves. The Athenians had then no fleet with which to put the pirates down, and possessed not so much land as would make a large estate in England: other little free towns held the rest of the surrounding country. King Ægeus was young, and desired to take a wife, indeed a wife had been found for him. But he wanted to be certain, if he could, that he was to have sons to succeed him: so many misfortunes happen to kings who have no children. But how was he to find out whether he should have children or not? At that time, and always in Greece before it was converted to Christianity, there were temples of the gods in various places, at which it was supposed that men might receive answers to their questions. These temples were called oracles, or places where oracles were given, and the most famous of them was the temple of Apollo at Pytho, or Delphi, far to the north-west of Athens. Here was a deep ravine of a steep mountain, where the god Apollo was said to have shot a monstrous dragon with his arrows. He then ordered that a temple should be built here, and in this temple a maiden, being inspired by the god, gave her prophecies. The people who came to consult her made the richest presents to the priests, and the temple was full of cups and bowls of gold and silver, and held more wealth in its chambers than the treasure houses of the richest kings.
