Hesiod, The Homeric Hymns, and Homerica
Page: 47(ll. 613-616) So it is not possible to deceive or go beyond the will of Zeus; for not even the son of Iapetus, kindly Prometheus, escaped his heavy anger, but of necessity strong bands confined him, although he knew many a wile.
(ll. 617-643) But when first their father was vexed in his heart with Obriareus and Cottus and Gyes, he bound them in cruel bonds, because he was jealous of their exceeding manhood and comeliness and great size: and he made them live beneath the wide-pathed earth, where they were afflicted, being set to dwell under the ground, at the end of the earth, at its great borders, in bitter anguish for a long time and with great grief at heart. But the son of Cronos and the other deathless gods whom rich-haired Rhea bare from union with Cronos, brought them up again to the light at Earth's advising. For she herself recounted all things to the gods fully, how that with these they would gain victory and a glorious cause to vaunt themselves. For the Titan gods and as many as sprang from Cronos had long been fighting together in stubborn war with heart-grieving toil, the lordly Titans from high Othyrs, but the gods, givers of good, whom rich-haired Rhea bare in union with Cronos, from Olympus. So they, with bitter wrath, were fighting continually with one another at that time for ten full years, and the hard strife had no close or end for either side, and the issue of the war hung evenly balanced. But when he had provided those three with all things fitting, nectar and ambrosia which the gods themselves eat, and when their proud spirit revived within them all after they had fed on nectar and delicious ambrosia, then it was that the father of men and gods spoke amongst them:
(ll. 644-653) 'Hear me, bright children of Earth and Heaven, that I may say what my heart within me bids. A long while now have we, who are sprung from Cronos and the Titan gods, fought with each other every day to get victory and to prevail. But do you show your great might and unconquerable strength, and face the Titans in bitter strife; for remember our friendly kindness, and from what sufferings you are come back to the light from your cruel bondage under misty gloom through our counsels.'
(ll. 654-663) So he said. And blameless Cottus answered him again: 'Divine one, you speak that which we know well: nay, even of ourselves we know that your wisdom and understanding is exceeding, and that you became a defender of the deathless ones from chill doom. And through your devising we are come back again from the murky gloom and from our merciless bonds, enjoying what we looked not for, O lord, son of Cronos. And so now with fixed purpose and deliberate counsel we will aid your power in dreadful strife and will fight against the Titans in hard battle.'
