The Iliad 5.548–562

Now when the twain had reached manhood, they followed with the Argives on the black ships to Ilios famed for its horses, seeking to win recompense for the sons of Atreus, Agamemnon and Menelaus; but their own selves in that land did the doom of death enfold. Like them two lions upon the mountain tops are reared by their dam in the thickets of a deep wood; and the twain snatch cattle and goodly sheep and make havoc of the farmsteads of men, until themuselves are slain by the hands of men with the sharp bronze; even in such wise were these twain vanquished beneath the hands of Aeneas, and fell like tall fir-trees. But as they fell Menelaus dear to Ares had pity for them, and strode through the foremost fighters, harnessed in flaming bronze and brandishing his spear; and Ares roused his might with intent that he might be vanquished beneath the hands of Aeneas.
