Hesiod, The Homeric Hymns, and Homerica
Page: 44(ll. 453-491) But Rhea was subject in love to Cronos and bare splendid children, Hestia 1618, Demeter, and gold-shod Hera and strong Hades, pitiless in heart, who dwells under the earth, and the loud-crashing Earth-Shaker, and wise Zeus, father of gods and men, by whose thunder the wide earth is shaken. These great Cronos swallowed as each came forth from the womb to his mother's knees with this intent, that no other of the proud sons of Heaven should hold the kingly office amongst the deathless gods. For he learned from Earth and starry Heaven that he was destined to be overcome by his own son, strong though he was, through the contriving of great Zeus 1619. Therefore he kept no blind outlook, but watched and swallowed down his children: and unceasing grief seized Rhea. But when she was about to bear Zeus, the father of gods and men, then she besought her own dear parents, Earth and starry Heaven, to devise some plan with her that the birth of her dear child might be concealed, and that retribution might overtake great, crafty Cronos for his own father and also for the children whom he had swallowed down. And they readily heard and obeyed their dear daughter, and told her all that was destined to happen touching Cronos the king and his stout-hearted son. So they sent her to Lyetus, to the rich land of Crete, when she was ready to bear great Zeus, the youngest of her children. Him did vast Earth receive from Rhea in wide Crete to nourish and to bring up. Thither came Earth carrying him swiftly through the black night to Lyctus first, and took him in her arms and hid him in a remote cave beneath the secret places of the holy earth on thick-wooded Mount Aegeum; but to the mightily ruling son of Heaven, the earlier king of the gods, she gave a great stone wrapped in swaddling clothes. Then he took it in his hands and thrust it down into his belly: wretch! he knew not in his heart that in place of the stone his son was left behind, unconquered and untroubled, and that he was soon to overcome him by force and might and drive him from his honours, himself to reign over the deathless gods.
(ll. 492-506) After that, the strength and glorious limbs of the prince increased quickly, and as the years rolled on, great Cronos the wily was beguiled by the deep suggestions of Earth, and brought up again his offspring, vanquished by the arts and might of his own son, and he vomited up first the stone which he had swallowed last. And Zeus set it fast in the wide-pathed earth at goodly Pytho under the glens of Parnassus, to be a sign thenceforth and a marvel to mortal men 1620. And he set free from their deadly bonds the brothers of his father, sons of Heaven whom his father in his foolishness had bound. And they remembered to be grateful to him for his kindness, and gave him thunder and the glowing thunderbolt and lightening: for before that, huge Earth had hidden these. In them he trusts and rules over mortals and immortals.
