Here's one version of The War of the Titans, as told by Hesiod in the Theogony (this version is translated by Hugh G. Evelyn-White). Dig in.
(ll. 116-138) Verily at the first Chaos came to be, but next wide-bosomed Earth, the ever-sure foundations of all (4) the deathless ones who hold the peaks of snowy Olympus, and dim Tartarus in the depth of the wide-pathed Earth, and Eros (Love), fairest among the deathless gods, who unnerves the limbs and overcomes the mind and wise counsels of all gods and all men within them. From Chaos came forth Erebus and black Night; but of Night were born Aether (5) and Day, whom she conceived and bare from union in love with Erebus. And Earth first bare starry Heaven, equal to herself, to cover her on every side, and to be an ever-sure abiding-place for the blessed gods. And she brought forth long Hills, graceful haunts of the goddess-Nymphs who dwell amongst the glens of the hills. She bare also the fruitless deep with his raging swell, Pontus, without sweet union of love. But afterwards she lay with Heaven and bare deep-swirling Oceanus, Coeus and Crius and Hyperion and Iapetus, Theia and Rhea, Themis and Mnemosyne and gold-crowned Phoebe and lovely Tethys. After them was born Cronos the wily, youngest and most terrible of her children, and he hated his lusty sire.
(ll. 139-146) And again, she bare the Cyclopes, overbearing in spirit, Brontes, and Steropes and stubborn-hearted Arges (6), who gave Zeus the thunder and made the thunderbolt: in all else they were like the gods, but one eye only was set in the midst of their fore-heads. And they were surnamed Cyclopes (Orb-eyed) because one orbed eye was set in their foreheads. Strength and might and craft were in their works.
(ll. 147-163) And again, three other sons were born of Earth and Heaven, great and doughty beyond telling, Cottus and Briareos and Gyes, presumptuous children. From their shoulders sprang an hundred arms, not to be approached, and each had fifty heads upon his shoulders on their strong limbs, and irresistible was the stubborn strength that was in their great forms. For of all the children that were born of Earth and Heaven, these were the most terrible, and they were hated by their own father from the first.
And he used to hide them all away in a secret place of Earth so soon as each was born, and would not suffer them to come up into the light: and Heaven rejoiced in his evil doing. But vast Earth groaned within, being straitened, and she made the element of grey flint and shaped a great sickle, and told her plan to her dear sons. And she spoke, cheering them, while she was vexed in her dear heart:
(ll. 164-166) `My children, gotten of a sinful father, if you will obey me, we should punish the vile outrage of your father; for he first thought of doing shameful things.'
(ll. 167-169) So she said; but fear seized them all, and none of them uttered a word. But great Cronos the wily took courage and answered his dear mother:
(ll. 170-172) `Mother, I will undertake to do this deed, for I reverence not our father of evil name, for he first thought of doing shameful things.'
(ll. 173-175) So he said: and vast Earth rejoiced greatly in spirit, and set and hid him in an ambush, and put in his hands a jagged sickle, and revealed to him the whole plot.
(ll. 176-206) And Heaven came, bringing on night and longing for love, and he lay about Earth spreading himself full upon her (7).
Then the son from his ambush stretched forth his left hand and in his right took the great long sickle with jagged teeth, and swiftly lopped off his own father's members and cast them away to fall behind him. And not vainly did they fall from his hand; for all the bloody drops that gushed forth Earth received, and as the seasons moved round she bare the strong Erinyes and the great Giants with gleaming armour, holding long spears in their hands and the Nymphs whom they call Meliae (8) all over the boundless earth. And so soon as he had cut off the members with flint and cast them from the land into the surging sea, they were swept away over the main a long time: and a white foam spread around them from the immortal flesh, and in it there grew a maiden. First she drew near holy Cythera, and from there, afterwards, she came to sea-girt Cyprus, and came forth an awful and lovely goddess, and grass grew up about her beneath her shapely feet. Her gods and men call Aphrodite, and the foam-born goddess and rich-crowned Cytherea, because she grew amid the foam, and Cytherea because she reached Cythera, and Cyprogenes because she was born in billowy Cyprus, and Philommedes (9) because sprang from the members. And with her went Eros, and comely Desire followed her at her birth at the first and as she went into the assembly of the gods. This honour she has from the beginning, and this is the portion allotted to her amongst men and undying gods, -- the whisperings of maidens and smiles and deceits with sweet delight and love and graciousness.
(ll. 207-210) But these sons whom be begot himself great Heaven used to call Titans (Strainers) in reproach, for he said that they strained and did presumptuously a fearful deed, and that vengeance for it would come afterwards.
(ll. 453-491) But Rhea was subject in love to Cronos and bare splendid children, Hestia (18), 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 (19). 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 (20). 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.
(ll. 617-643) 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.'
(ll. 664-686) So he said: and the gods, givers of good things, applauded when they heard his word, and their spirit longed for war even more than before, and they all, both male and female, stirred up hated battle that day, the Titan gods, and all that were born of Cronos together with those dread, mighty ones of overwhelming strength whom Zeus brought up to the light from Erebus beneath the earth. An hundred arms sprang from the shoulders of all alike, and each had fifty heads growing upon his shoulders upon stout limbs. These, then, stood against the Titans in grim strife, holding huge rocks in their strong hands. And on the other part the Titans eagerly strengthened their ranks, and both sides at one time showed the work of their hands and their might. The boundless sea rang terribly around, and the earth crashed loudly: wide Heaven was shaken and groaned, and high Olympus reeled from its foundation under the charge of the undying gods, and a heavy quaking reached dim Tartarus and the deep sound of their feet in the fearful onset and of their hard missiles. So, then, they launched their grievous shafts upon one another, and the cry of both armies as they shouted reached to starry heaven; and they met together with a great battle-cry.
(ll. 687-712) Then Zeus no longer held back his might; but straight his heart was filled with fury and he showed forth all his strength. From Heaven and from Olympus he came forthwith, hurling his lightning: the bold flew thick and fast from his strong hand together with thunder and lightning, whirling an awesome flame. The life-giving earth crashed around in burning, and the vast wood crackled loud with fire all about. All the land seethed, and Ocean's streams and the unfruitful sea. The hot vapour lapped round the earthborn Titans: flame unspeakable rose to the bright upper air: the flashing glare of the thunder- stone and lightning blinded their eyes for all that there were strong. Astounding heat seized Chaos: and to see with eyes and to hear the sound with ears it seemed even as if Earth and wide Heaven above came together; for such a mighty crash would have arisen if Earth were being hurled to ruin, and Heaven from on high were hurling her down; so great a crash was there while the gods were meeting together in strife. Also the winds brought rumbling earthquake and duststorm, thunder and lightning and the lurid thunderbolt, which are the shafts of great Zeus, and carried the clangour and the warcry into the midst of the two hosts. An horrible uproar of terrible strife arose: mighty deeds were shown and the battle inclined. But until then, they kept at one another and fought continually in cruel war.
(ll. 713-735) And amongst the foremost Cottus and Briareos and Gyes insatiate for war raised fierce fighting: three hundred rocks, one upon another, they launched from their strong hands and overshadowed the Titans with their missiles, and buried them beneath the wide-pathed earth, and bound them in bitter chains when they had conquered them by their strength for all their great spirit, as far beneath the earth to Tartarus. For a brazen anvil falling down from heaven nine nights and days would reach the earth upon the tenth: and again, a brazen anvil falling from earth nine nights and days would reach Tartarus upon the tenth. Round it runs a fence of bronze, and night spreads in triple line all about it like a neck-circlet, while above grow the roots of the earth and unfruitful sea. There by the counsel of Zeus who drives the clouds the Titan gods are hidden under misty gloom, in a dank place where are the ends of the huge earth. And they may not go out; for Poseidon fixed gates of bronze upon it, and a wall runs all round it on every side. There Gyes and Cottus and great-souled Obriareus live, trusty warders of Zeus who holds the aegis.
(ll. 736-744) And there, all in their order, are the sources and ends of gloomy earth and misty Tartarus and the unfruitful sea and starry heaven, loathsome and dank, which even the gods abhor.
It is a great gulf, and if once a man were within the gates, he would not reach the floor until a whole year had reached its end, but cruel blast upon blast would carry him this way and that. And this marvel is awful even to the deathless gods.
(ll. 820-868) But when Zeus had driven the Titans from heaven, huge Earth bare her youngest child Typhoeus of the love of Tartarus, by the aid of golden Aphrodite. Strength was with his hands in all that he did and the feet of the strong god were untiring. From his shoulders grew an hundred heads of a snake, a fearful dragon, with dark, flickering tongues, and from under the brows of his eyes in his marvellous heads flashed fire, and fire burned from his heads as he glared. And there were voices in all his dreadful heads which uttered every kind of sound unspeakable; for at one time they made sounds such that the gods understood, but at another, the noise of a bull bellowing aloud in proud ungovernable fury; and at another, the sound of a lion, relentless of heart; and at anothers, sounds like whelps, wonderful to hear; and again, at another, he would hiss, so that the high mountains re-echoed. And truly a thing past help would have happened on that day, and he would have come to reign over mortals and immortals, had not the father of men and gods been quick to perceive it. But he thundered hard and mightily: and the earth around resounded terribly and the wide heaven above, and the sea and Ocean's streams and the nether parts of the earth. Great Olympus reeled beneath the divine feet of the king as he arose and earth groaned thereat. And through the two of them heat took hold on the dark-blue sea, through the thunder and lightning, and through the fire from the monster, and the scorching winds and blazing thunderbolt. The whole earth seethed, and sky and sea: and the long waves raged along the beaches round and about, at the rush of the deathless gods: and there arose an endless shaking. Hades trembled where he rules over the dead below, and the Titans under Tartarus who live with Cronos, because of the unending clamour and the fearful strife. So when Zeus had raised up his might and seized his arms, thunder and lightning and lurid thunderbolt, he leaped form Olympus and struck him, and burned all the marvellous heads of the monster about him. But when Zeus had conquered him and lashed him with strokes, Typhoeus was hurled down, a maimed wreck, so that the huge earth groaned. And flame shot forth from the thunder- stricken lord in the dim rugged glens of the mount (26), when he was smitten. A great part of huge earth was scorched by the terrible vapour and melted as tin melts when heated by men's art in channelled (27) crucibles; or as iron, which is hardest of all things, is softened by glowing fire in mountain glens and melts in the divine earth through the strength of Hephaestus (28). Even so, then, the earth melted in the glow of the blazing fire. And in the bitterness of his anger Zeus cast him into wide Tartarus.
(ll. 881-885) But when the blessed gods had finished their toil, and settled by force their struggle for honours with the Titans, they pressed far-seeing Olympian Zeus to reign and to rule over them, by Earth's prompting. So he divided their dignities amongst them.
