"Safety Lies Midway"

Context: Phaëthon, son of Clymene and Phoebus, the sun-god, is taunted by a friend and wants to prove that Pheobus is his father. He goes to the sun-god's palace and begs him to grant a wish to which Phoebus gladly consents. Phaëthon then tells his father that he wants to drive the sun chariot across the sky. Phoebus immediately regrets his promise, telling his son that there are many dangers, that the steeds are difficult for even him to handle. But Phaëthon insists. With a sad heart Phoebus agrees, and gives his son this advice:

Five zones there are: your course, confined to three;
The farthest north and south must never see.
Next, share your heat between the earth and sky;
Press not too low, nor set your course too high.
Heaven's halls will kindle if too high you stray;
Too low, the earth: your safety lies midway.
