Dragon/Ymir/Typhon

[granpa]

12 And there appeared a great wonder in heaven; a woman clothed with the sun, and the moon under her feet, and upon her head a crown of twelve stars:

2 And she being with child cried, travailing in birth, and pained to be delivered.

3 And there appeared another wonder in heaven; and behold a great red dragon, having seven heads and ten horns, and seven crowns upon his heads.

4 And his tail drew the third part of the stars of heaven, and did cast them to the earth: and the dragon stood before the woman which was ready to be delivered, for to devour her child as soon as it was born.

5 And she brought forth a man child, who was to rule all nations with a rod of iron: and her child was caught up unto God, and to his throne.

6 And the woman fled into the wilderness (Eden), where she hath a place prepared of God, that they should feed her there a thousand two hundred and threescore days.

7 And there was war in heaven: Michael and his angels fought against the dragon; and the dragon fought and his angels,

8 And prevailed not; neither was their place found any more in heaven.

9 And the great dragon was cast out, that old serpent, called the Devil, and Satan, which deceiveth the whole world: he was cast out into the earth, and his angels were cast out with him.

This obviously takes place in the garden of Eden.

many world mythologies describe a dragon existing in the beginning.

From the void that was the rest of the universe, the first god, Ometeotl, created itself. Ometeotl was both male and female, good and evil, light and darkness, fire and water, judgment and forgiveness, the god of duality. Ometeotl gave birth to four children, the four Tezcatlipocas, who each preside over one of the four cardinal directions.

It was these four gods who eventually created all the other gods and the world we know today, but before they could create they had to destroy, for every time they attempted to create something, it would fall into the water beneath them and be eaten by Cipactli, the giant earth crocodile, who swam through the water with mouths at every one of her joints.

The deity Tezcatlipoca sacrificed a foot when he used it as bait to draw the monster nearer. He and Quetzalcoatl created the earth from its body.

In the beginning, there were two regions: Muspellsheimr in the south, full of fire, light and heat; and Niflheimr in the north, full of arctic waters, mists, and cold.[3] Between them stretched the yawning emptiness of Ginnungagap, and into it poured sparks and smoke from the south and layers of rime-ice and glacial rivers from the north. As heat and cold met in Ginnungagap, a living Jötunn, Ymir, appeared in the melting ice. From his left armpit, the first man and woman were born. From his legs, the frost jötnar were born, making Ymir the progenitor of the jötnar. Most sources identify Ymir's oldest son as Thrudgelmir, who bore Ymir's grandson, Bergelmir. The other jötnar are usually unnamed. Ymir fed on the milk of the cow Auðhumla. She licked the blocks of salty ice, releasing Búri.

Buri's son Borr had three sons, the gods Odin, Vili and Vé. The three slew Ymir, and all of the jötnar (giants) except for Bergelmir and his wife

The gods Odin, Vili, and Vé fashioned the Earth (elsewhere personified as a goddess; Jörð) from his flesh, from his blood the ocean, from his bones the hills, from his hair the trees, from his brains the clouds, from his skull the heavens, and from his eyebrows the middle realm in which mankind lives, Midgard

In the Rigveda, Purusha is described as a primeval giant that is sacrificed by the gods (see Purushamedha) and from whose body the world and the varnas (classes) are built. He is described as having a thousand heads and a thousand feet.

Much later we have:

20 And I saw an angel coming down out of heaven, having the key to the Abyss and holding in his hand a great chain. 2 He seized the dragon, that ancient serpent, who is the devil, or Satan, and bound him for a thousand years. 3 He threw him into the Abyss, and locked and sealed it over him, to keep him from deceiving the nations anymore until the thousand years were ended. After that, he must be set free for a short time.
The Judgment of Satan

7 When the thousand years are over, Satan will be released from his prison 8 and will go out to deceive the nations in the four corners of the earth—Gog and Magog—and to gather them for battle. In number they are like the sand on the seashore. 9 They marched across the breadth of the earth and surrounded the camp of God’s people, the city he loves. But fire came down from heaven and devoured them

But when Zeus had driven the Titans from Olympus,
mother Earth bore her youngest child Typhoeus of the love of
Tartarus, by the aid of golden Aphrodite.

—Hesiod, Theogony 820–822.

Typhon was described in pseudo-Apollodorus, Bibliotheke, as the largest and most fearsome of all creatures. His human upper half reached as high as the stars, and his hands reached east and west. Instead of a human head, a hundred dragon heads erupted from his neck and shoulders (some, however, depict him as having a human head, with the dragon heads replacing the fingers on his hands). His bottom half consisted of gigantic viper coils that could reach the top of his head when stretched out and constantly made a hissing noise. His whole body was covered in wings, and fire flashed from his eyes, striking fear even into the Olympians.

This would be around the time of Atlantis.
