Refutation of All Heresies 1.26.2

So, calling the nine Muses from Pieria, that is, from Olympus, he asked to be taught … "how at first gods and earth came to be, and rivers and the boundless sea with its swelling surge, and the gleaming stars and the wide heaven above, how they divided the wealth and how they shared out the honors, and also how at first they held Olympus of many folds." … "These things tell me, Muses," he says, "from the beginning, and say which of them first came to be. First of all Chaos came to be, and then broad-breasted Earth, the ever-sure seat of all the immortals who hold the peaks of snowy Olympus, and misty Tartarus in the depth of the wide-wayed earth, and Eros, who is fairest among the immortal gods, the limb-loosener, who in the breasts of all gods and all men subdues the mind and prudent counsel. From Chaos came Erebus and black Night; and from Night in turn came Ether and Day. And Earth first bore, equal to herself, starry Heaven, to cover her all round, that it might be an ever-sure seat for the blessed gods. And she bore the long mountains, pleasant haunts of the gods, of the Nymphs who dwell in the wooded mountains. And she bore also the unharvested deep, raging with its swell, the Sea, without delightful love; and then, lying with Heaven, she bore deep-eddying Ocean, and Coeus and Crius and Hyperion and Iapetus, and Theia and Rhea and Themis and Mnemosyne, and gold-crowned Phoebe and lovely Tethys. After them youngest was born Cronus of crooked counsel, most terrible of children, and he hated his lusty father. And she bore also the Cyclopes, with overbearing heart." And he enumerates all the other Giants from Cronus. And later, somewhere, Zeus was born of Rhea.
