For if ye are in truth of heavenly race, or have come in no wise inferior to me, to win the goods of strangers, I will give thee the fleece to bear away, if thou dost wish, when I have tried thee.

For against brave men I bear no grudge, such as ye yourselves tell me of him who bears sway in Hellas.

And the trial of your courage and might shall be a contest which I myself can compass with my hands, deadly though it be.

Two bulls with feet of bronze I have that pasture on the plain of Ares, breathing forth flame from their jaws; them do I yoke and drive over the stubborn field of Ares, four plough-gates; and quickly cleaving it with the share up to the headland, I cast into the furrows the seed, not the corn of Demeter, but the teeth of a dread serpent that grow up into the fashion of armed men; them I slay at once, cutting them down beneath my spear as they rise against me on all sides.

In the morning do I yoke the oxen, and at eventide I cease from the harvesting.
