Apollo made one last plea.
"Look the universe over, my son," he entreated, "and choose whatever is most precious in the earth or on the sea. This will I give you in proof that you are my son, but take back your other, rash request."
"I have only one wish, to drive the chariot of the Sun," Phaeton answered stubbornly.
There was but one course left then for Apollo, because a god could never break his promise. Without a word he led Phaeton to the great stable where he kept his lofty chariot.
The chariot was a gift of Vulcan to Apollo, and made of gold. The axle was of gold, the pole and wheels also of gold, and the spokes of the brightest silver. There were rows of chrysolites and diamonds along the seat that reflected the rays of the sun. Apollo ordered the Hours to harness the horses and they led the steeds, full fed with ambrosia, from the stalls, and attached the reins. As Phaeton, full of pride, watched he saw that Dawn had thrown open the purple gates of the east and his pathway, strewn with roses, stretched before him. He seated himself in the chariot and took the reins.
Apollo anointed his son's face with a powerful unguent that would make it possible for him to endure the flaming heat of the sun. He set the rays of light on his head and said sorrowfully,
"If you will be so rash, I beg of you to hold the reins more tightly than you ever did before and spare the whip. The horses go fast enough of their own accord, and the difficulty is to hold them in. You are not to take the direct road, but turn to the left. You will see the marks of my wheels and these will guide you. Go not too high, or you will set the heavenly dwellings on fire, or so low as to burn the earth, but keep to the middle course which is best. Night is just passing out of the western gates so you can delay no longer. Start the chariot, and may your chance work better for you than you have planned."
Phaeton stood up in the gilded chariot, lifted the reins, and was off like a dart.
In an instant the snorting, fiery horses discovered that they were carrying a lighter load than usual and they dashed through the clouds as if the chariot had been empty. It reeled and was tossed about like a ship at sea without ballast. The bars of the sky were let down and the limitless plain of the universe lay before the horses. They left Apollo's travelled course and Phaeton was powerless to guide them. He looked down at the earth so far below him, and he grew pale and his knees shook with terror. He turned his eyes on the trackless heavens in front of him and was even more terrified to see the huge forms among which he rode as if he was driven by a tempest; the Archer, the Great Bear, the Lion and the Crab. All those monsters of whom Apollo had warned him were there, and others too.
Phaeton wished he had never left the earth, never made so bold a request of his father. He lost his self command and could not tell whether to draw the reins tightly or let them loose. He forgot the names of the steeds. At last, as he saw the Scorpion directly in his path, its two great arms extended and its fangs reeking with poison, he lost all his courage and the reins dropped from his hands. As the horses felt their loosened harness, they dashed away headlong into unknown regions of the sky, now up in high heaven among the stars and then hurling the chariot down almost to the earth.
