In the city of Ephyre, now called Corinth, was a king named Glaucus, who had a son, Bellerophon. He was brought up far from home, in Argos, by King Proetus (the great-uncle of Perseus), who was his foster-father, and loved him well. Proetus was an old man, but his wife, Anteia, was young and beautiful, and Bellerophon also was beautiful and young, and, by little and little, Anteia fell in love with him, and could not be happy without him, but no such love was in Bellerophon's heart for her, who was his foster-mother. At last Anteia, forgetting all shame, told Bellerophon that she loved him, and hated her husband; and she asked him to fly with her to the seashore, where she had a ship lying ready, and they two would sail to some island far away, and be happy together.
Bellerophon knew not what to say; he could not wrong King Proetus, his foster-father. He stood speechless, his face was red with shame, but the face of Anteia grew white with rage.
'Dastard!' she said, 'thou shalt not live long in Argos to boast of my love and your own virtue!' She ran from him, straight to King Proetus, and flung herself at his feet. 'What shall be done, oh king,' she cried, 'to the man who speaks words of love dishonourable to the Queen of Argos?'
'By the splendour of Zeus,' cried Proetus, 'if he were my own foster-son he shall die!'
'Thou hast named him!' said Anteia, and she ran to her own upper chamber, and locked the door, and flung herself on the bed, weeping for rage as if her heart would break. Proetus followed her, but she would not unlock her door, only he heard her bitter weeping, and he went apart, alone, and took thought how he should be revenged on Bellerophon. He had no desire to slay him openly, for then the King of Ephyre would make war against him. He could not bring him to trial before the judges, for there was no witness against him except Anteia; and he did not desire to make his subjects talk about the queen, for it was the glory of a woman, in those days, not to be spoken of in the conversation of men.
Therefore Proetus, for a day or two, seemed to favour Bellerophon more kindly than ever. Next he called him into his chamber, alone, and said that it was well for young men to see the world, to cross the sea and visit foreign cities, and win renown. The eyes of Bellerophon brightened at these words, not only because he desired to travel, but because he was miserable in Argos, where he saw every day the angry eyes of Anteia. Then Proetus said that the King of Lycia, in Asia far across the sea, was his father-in-law, and his great friend. To him he would send Bellerophon, and Proetus gave him a folded tablet, in which he had written many deadly signs. Bellerophon took the folded tablet, not looking, of course, at what was written in it, and away he sailed to Lycia. The king of that country received him well, and on the tenth day after his arrival asked him if he brought any token from King Proetus.
Bellerophon gave him the tablet, which he opened and read. The writing said that Bellerophon must die. Now at that time Lycia was haunted by a monster of no human birth; her front was the front of a lion, in the middle of her body she was a goat, she tapered away to a strong swift serpent, and she breathed flame from her nostrils. The King of Lycia, wishing to get rid of Bellerophon, had but to name this curse to his guest, who vowed that he would meet her if he might find her. So he was led to the cavern where she dwelt, and there he watched for her all night till the day dawned.
He was cunning as well as brave, and men asked him why he took with him no weapon but his sword, and two spears with heavy heads, not of bronze, but of soft lead. Bellerophon told his companions that he had his own way of fighting, and bade them go home, and leave him alone, while his charioteer stood by the horses and chariot in a hollow way, out of sight. Bellerophon himself watched, lying on his face, hidden behind a rock in the mouth of the cavern. The moment that the rising sun touched with a red ray the dark mouth of the cave, forth came the Chimaera, and, setting her fore paws on the rock, looked over the valley. The moment that she opened her mouth, breathing flame, Bellerophon plunged his leaden spears deep down her throat, and sprang aside. On came the Chimaera, her serpent tail lashing the stones, but Bellerophon ever kept on the further side of a great tall rock. The Chimaera ceased to pursue him, she rolled on the earth, uttering screams of pain, for the lead was melting in the fire that was within her, and at last the molten lead burned through her, and she died. Bellerophon hacked off her head, and several feet of her tail, stowed them in his chariot, and drove back to the palace of the King of Lycia, while the people followed him with songs of praise.
The king set him three other terrible tasks, but he achieved each of the adventures gloriously, and the king gave him his daughter to be his bride, and half of all the honours of his kingdom. This is the story of Bellerophon (there were other ways of telling it), and Perseus was determined to do as great deeds as he. But Perseus was still a boy, and he did not know, and no man could tell him, the way to the island of the Gorgons.
When Perseus was about sixteen years old, the King of Seriphos, Polydectes, saw Danae, fell in love with her, and wanted to take her into his palace, but he did not want Perseus. He was a bad and cruel man, but Perseus was so much beloved by the people that he dared not kill him openly. He therefore made friends with the lad, and watched him carefully to see how he could take advantage of him. The king saw that he was of a rash, daring and haughty spirit, though Dictys had taught him to keep himself well in hand, and that he was eager to win glory. The king fell on this plan: he gave a great feast on his birthday, and invited all the chief men and the richest on the island; Perseus, too, he asked to the banquet. As the custom was, all the guests brought gifts, the best that they had, cattle, women-slaves, golden cups, wedges of gold, great vessels of bronze, and other splendid things, and the king met the guests at the door of his hall, and thanked them graciously.
