Prometheus monologue — Specimens of Greek Tragedy — Aeschylus and Sophocles

Yet, yet shall Zeus, for all his proud self-will, Be humbled. On a wedlock he is bent Whereof the fateful offspring shall one day Hurl him from sovereignty to nothingness, And so fulfil the curse old Chronos spake, When from his immemorial throne he fell. And this his doom how to escape not one Of all the gods can rede him saving I. But to me all is known. Then let him sit Triumphant while his thunders roll through heaven, And his hand grasps the flaming thunderbolt; All his artillery shall not save its lord From utter shame and ruin bottomless. Such the antagonist himself arrays Against himself, dread and invincible, One who a fiercer than the lightning's flame, A louder than the thunder's peal shall find, And wrest the truncheon that makes earth to quake, Poseidon's trident, from its wielder's hand. Wrecked on misfortune's rock, he then shall know How high it is to reign, to serve how low.
