Bk II:90-110 Phaethon insists on driving the chariot.
"No doubt, since you ask for a certain sign to give you confidence in being born of my blood, I give you that sure sign by fearing for you, and show myself a father by fatherly anxiety. Look at me. If only you could look into my heart, and see a father's concern from within! Finally, look around you, at the riches the world holds, and ask for anything from all of the good things in earth, sea, and sky. I can refuse you nothing. Only this one thing I take exception to, which would truly be a punishment and not an honour. Phaethon, you ask for punishment as your reward! Why do you unknowingly throw your coaxing arms around my neck? Have no doubt! Whatever you ask will be given, I have sworn it by the Stygian streams, but make a wiser choice!"
The warning ended, but Phaethon still rejected his words, and pressed his purpose, blazing with desire to drive the chariot. So, as he had the right, his father led the youth to the high chariot, Vulcan's work. It had an axle of gold, and a gold chariot pole, wheels with golden rims, and circles of silver spokes. Along the yoke chrysolites and gemstones, set in order, glowed with brilliance reflecting Phoebus's own light.
