So against Paris's guilty boast
Zeus, witness between guest and host,
Sends Atreus' sons for stern redress
Of his and Helen's wantonness.
Now Greece and Troy both pay their equal debt
Of aching limbs and wounds and sweat,
While knees sink low in gory dust,
And spears are shivered at first thrust.
Aeschylus, Agamemnon, 60-67
You now speak more in wisdom,
Naming the thrice-gorged Fury
That hates and haunts our race.
Hers is the thirst of slaughter,
Still slaked with feud and vengeance,
Till, with each wrong requited,
A new thirst takes its place.
Aeschylus, Agamemnon, 1475-81
