gleam brightly, kindling the ravening flame, and anon cease from
blowing, and a terrible roar rises from the fire when it darts up from
below; so the bulls roared, breathing forth swift flame from their
mouths, while the consuming heat played round him, smiting like
lightning; but the maiden's charms protected him. Then grasping the tip
of the horn of the right-hand bull, he dragged it mightily with all his
strength to bring it near the yoke of bronze, and forced it down on to
its knees, suddenly striking with his foot the foot of bronze. So also
he threw the other bull on to its knees as it rushed upon him, and smote
it down with one blow. And throwing to the ground his broad shield, he
held them both down where they had fallen on their fore-knees, as he
strode from side to side, now here, now there, and rushed swiftly
through the flame. But Aeetes marvelled at the hero's might. And
meantime the sons of Tyndareus--for long since had it been thus ordained
for them--near at hand gave him the yoke from the ground to cast round
them. Then tightly did he bind their necks; and lifting the pole of
bronze between them, he fastened it to the yoke by its golden tip. So
the twin heroes started back from the fire to the ship. But Jason took
up again his shield and cast it on his back behind him, and grasped the
strong helmet filled with sharp teeth, and his resistless spear,
wherewith, like some ploughman with a Pelasgian goad, he pricked the
bulls beneath, striking their flanks; and very firmly did he guide the
well fitted plough handle, fashioned of adamant.

The bulls meantime raged exceedingly, breathing forth furious flame of
fire; and their breath rose up like the roar of blustering winds, in
fear of which above all seafaring men furl their large sail. But not
long after that they moved on at the bidding of the spear; and behind
them the rugged fallow was broken up, cloven by the might of the bulls
and the sturdy ploughman. Then terribly groaned the clods withal along
the furrows of the plough as they were rent, each a man's burden; and
Jason followed, pressing down the cornfield with firm foot; and far from
him he ever sowed the teeth along the clods as each was ploughed,
turning his head back for fear lest the deadly crop of earthborn men
should rise against him first; and the bulls toiled onwards treading
with their hoofs of bronze.

But when the third part of the day was still left as it wanes from dawn,
and wearied lab
