_Then was my feature changed, my reason fled: Wearing these horns ye see, with frenzied hounds, Pricked and tormented by the gadfly’s sting, To fair Kerchneia’s stream and Lerna’s shore I hasted. And upon my traces still, Of rage unslaked, with myriad eyes agaze, The earth-born huntsman Argus followed hard. Him unawares a sudden death o’ertook, And reft him of his life. From land to land, Heaven’s scourge, the unsleeping gadfly, drives me still. My tale is told. What time has yet in store For me to suffer, tell me if thou canst: Not pitying think with lies to comfort me: False words I count of maladies the worst._[20] Io is asking more than she knows, and the prophecy that Prometheus will make to her is more wonderful than she could ever dream. In careful detail, and so impressively that she must remember every word, he indicates the first part of her wanderings. She must turn her face eastward, and faring through Scythia, pass along the sea-coast, avoiding the fierce Chalybes. Then on wearily to the range of the Caucasus, which she must ascend to the very summit; and following afterward a southward road, she will come to the land of the Amazons and down to the sea which separates the continents. Here she must boldly ford the strait, which in later times will be called Bosphorus because she, the cow-maiden, crossed it; and leaving Europe behind, she will tread on Asian soil. PROM. _... Deem ye not That this proud lord of heaven on great and small Tramples alike? For this poor mortal maid, Enamoured of her love, his godhead dooms To wander thus. Thy most imperious wooer, Maiden, thou well mayst rue. What I have told, Deem that the prelude hardly hast thou heard._ IO. _Woe’s me, alas, alas!... What boots it then to live? Were it not better From this hard rock to fling myself outright, That dashed to earth I might of all my toil Have riddance? Better surely once to die. Than all my days to be afflicted thus._[20] But Prometheus, looking further still into the future, sees some hope for her, as he contrasts her fate with his. However great her affliction, it must end some day; he can even foretell just what the issue will be, and when. But for him, suffering must continue until Zeus is hurled from his throne. IO. _Shall Zeus indeed be downcast from his throne?_ PROM. _To see that day methinks thou wouldst rejoice._ IO. _How could I but rejoice, whom he has wronged?_[20] She begs for a revelation of the fate of Zeus; and the titan tells briefly of a certain marriage that the god is contemplating, which must bring him ruin if Prometheus will not interpose. IO. _Who then shall loose thee in despite of Zeus?_
