One day she came to the sea, and as she fled along the beach she lifted up her hands and called aloud to great Neptune to help her. Neptune, the king of the sea, heard her and was kind to her. He sent a huge fish, called a dolphin, to bear her away from the cruel land; and the fish, with Leto sitting on his broad back, swam through the waves to Delos, a little island which lay floating on top of the water like a boat. There the gentle lady found rest and a home; for the place belonged to Neptune, and the words of cruel Juno were not obeyed there. Neptune put four marble pillars under the island so that it should rest firm upon them; and then he chained it fast, with great chains which reached to the bottom of the sea, so that the waves might never move it.

By and by twin babes were born to Leto in Delos. One was a boy whom she called Apollo, the other a girl whom she named Artemis, or Diana. When the news of their birth was carried to Jupiter and the Mighty Folk on the mountain top, all the world was glad. The sun danced on the waters, and singing swans flew seven times round the island of Delos. The moon stooped to kiss the babes in their cradle; and Juno forgot her anger, and bade all things on the earth and in the sky be kind to Leto.

The two children grew very fast. Apollo became tall and strong and graceful; his face was as bright as the sunbeams; and he carried joy and gladness with him wherever he went. Jupiter gave him a pair of swans and a golden chariot, which bore him over sea and land wherever he wanted to go; and he gave him a lyre on which he played the sweetest music that was ever heard, and a silver bow with sharp arrows which never missed the mark. When Apollo went out into the world, and men came to know about him, he was called by some the Bringer of Light, by others the Master of Song, and by still others the Lord of the Silver Bow.

Diana was tall and graceful, too, and very handsome. She liked to wander in the woods with her maids, who were called nymphs; she took kind care of the timid deer and the helpless creatures which live among the trees; and she delighted in hunting wolves and bears and other savage beasts. She was loved and feared in every land, and Jupiter made her the queen of the green woods and the chase.

"Where is the center of the world?"

This is the question which some one asked Jupiter as he sat in his golden hall. Of course the mighty ruler of earth and sky was too wise to be puzzled by so simple a thing, but he was too busy to answer it at once. So he said:

"Come again in one year from to-day, and I will show you the very place."

Then Jupiter took two swift eagles which could fly faster than the storm-wind, and trained them till the speed of the one was the same as that of the other. At the end of the year he said to his servants:

"Take this eagle to the eastern rim of the earth, where the sun rises out of the sea; and carry his fellow to the far west, where the ocean is lost in darkness and nothing lies beyond. Then, when I give you the sign, loosen both at the same moment."

The servants did as they were bidden, and carried the eagles to the outermost edges of the world. Then Jupiter clapped his hands. The lightning flashed, the thunder rolled, and the two swift birds were set free. One of them flew straight back towards the west, the other flew straight back towards the east; and no arrow ever sped faster from the bow than did these two birds from the hands of those who had held them.

On and on they went like shooting stars rushing to meet each other; and Jupiter and all his mighty company sat amid the clouds and watched their flight. Nearer and nearer they came, but they swerved not to the right nor to the left. Nearer and nearer—and then with a crash like the meeting of two ships at sea, the eagles came together in mid-air and fell dead to the ground.

"Who asked where is the center of the world?" said Jupiter. "The spot where the two eagles lie—that is the center of the world."

They had fallen on the top of a mountain in Greece which men have ever since called Parnassus.

"If that is the center of the world," said young Apollo, "then I will make my home there, and I will build a house in that place, so that my light may be seen in all lands."

So Apollo went down to Parnassus, and looked about for a spot in which to lay the foundations of his house. The mountain itself was savage and wild, and the valley below it was lonely and dark. The few people who lived there kept themselves hidden among the rocks as if in dread of some great danger. They told Apollo that near the foot of the mountain where the steep cliff seemed to be split in two there lived a huge serpent called the Python. This serpent often seized sheep and cattle, and sometimes even men and women and children, and carried them up to his dreadful den and devoured them.

"Can no one kill this beast?" said Apollo.

And they said, "No one; and we and our children and our flocks shall all be slain by him."

Then Apollo with his silver bow in his hands went up towards the place where the Python lay. The monster had worn great paths through the grass and among the rocks, and his lair was not hard to find. When he caught sight of Apollo, he uncoiled himself, and came out to meet him. The bright prince saw the creature's glaring eyes and blood-red mouth, and heard the rush of his scaly body over the stones. He fitted an arrow to his bow, and stood still. The Python saw that his foe was no common man, and turned to flee. Then the arrow sped from the bow—and the monster was dead.

"Here I will build my house," said Apollo.

Close to the foot of the steep cliff, and beneath the spot where Jupiter's eagles had fallen, he laid the foundations; and soon where had been the lair of the Python, the white walls of Apollo's temple arose among the rocks. Then the poor people of the land came and built their houses near by; and Apollo lived among them many years, and taught them to be gentle and wise, and showed them how to be happy. The mountain was no longer savage and wild, but was a place of music and song; the valley was no longer dark and lonely, but was filled with beauty and light.

"What shall we call our city?" the people asked.

"Call it Delphi, or the Dolphin," said Apollo; "for it was a dolphin that carried my mother across the sea."
