Next to them were horsemen hard set, and they contended and labored for a prize. The charioteers standing on their well-woven cars, urged on their swift horses with loose rein; the jointed cars flew along clattering and the naves of the wheels shrieked loudly.So they were engaged in an unending toil, and the end with victory came never to them, and the contest was ever unwon. And there was set out for them within the course a great tripod of gold, the splendid work of cunning Hephaestus. And round the rim Ocean was flowing, with a full stream as it seemed,and enclosed all the cunning work of the shield. Over it swans were soaring and calling loudly, and many others were swimming upon the surface of the water; and near them were shoals of fish. A wonderful thing the great strong shield was to see—even for Zeus the loud-thunderer, by whose will Hephaestus made itand 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. Then the goddess grey-eyed Athena came near them and spoke winged words, encouraging them: “Hail, offspring of far-famed Lynceus!

Then draw back; for it is not ordained that you should take his horses or his splendid armor.” So said the bright-eyed goddess and swiftly got up into the car with victory and renown in her hands.Then heaven-nurtured Iolaus called terribly to the horses, and at his cry they swiftly whirled the fleet chariot along, raising dust from the plain; for the goddess bright-eyed Athena put mettle into them by shaking her aegis. And the earth groaned all round them.And they, horse-taming Cycnus and Ares, insatiable in war, came on together like fire or whirlwind. Then their horses neighed shrilly, face to face; and the echo was shivered all round them. And mighty Heracles spoke first and said to that other:
