Lightning

A wonderful thing the great strong shield was to see -- even for Zeus the loud-thunderer, by whose will Hephaestus made it and fitted it with his hands. This shield the valiant son of Zeus wielded masterly, and leaped upon his horse-chariot like the lightning of his father Zeus who holds the aegis, moving lithely. And his charioteer, strong Iolaus, standing upon the car, guided the curved chariot.
