I've always been a little intrigued with the two-time creation of humanity in Hellenic mythology. While Christianity's end of humanity by way of deluge is much more well-known, and everyone knows about Noah and his ark, humanity in Hellenic mythology also ended and was revived. Story time:

After the Titanomachy--the war in which the Olympic Gods took control from the elder generation of Gods, the Titans--ended, Zeus claimed His throne as rightful King to the Deathless Ones. Humanity did not yet exist. While most Titans were locked away in Tartarus by Zeus, the Titans Prometheus and Epimetheus--who were brothers--had been either neutral or on the side of Zeus during the Titan War and were therefor given a task. Prometheus was given the task of creating man and Epimetheus was ordered to give good qualities to all creatures of earth. So did Prometheus and Epimetheus. Prometheus shaped man out of clay and Athena breathed life into him. Epimetheus spread swiftness, cunning, fur and wings but ran out of gifts when he came to man. Prometheus remedied the situation by allowing men to walk upright and gave them fire.

It soon became apparent that Prometheus loved man more than the Olympians. When Zeus decreed that man must give sacrifice to the Deathless Ones, Prometheus stood ready to aid humanity. He butchered an animal and divided it into piles; the bones and fat formed one of them, the good meat wrapped in the hide of the animal, the other. Zeus vowed that he would abide by the choice of sacrifice He made now, and picked the tasty looking pile of bones. Zeus was angered but could not take back his vow: from that point on, the Gods would get the fat and the bones from a sacrificed animal. The humans were entitled to the meat and the hide. What He could take back was the gift of fire, and this He did.

Mankind suffered greatly without fire and Prometheus traveled either to the sun or Olympus to reclaim fire for his beloved mankind. This, of course, angered Zeus even further and so He devised a plan. First, He imprisoned Prometheus. He ordered Hermes to tie Prometheus to a mountain and had a giant eagle come every day to eat his liver. As an immortal, Prometheus' liver grew back over night so his torment was endless. Before Prometheus had been taken prisoner, however, he had told his brother Epimetheus never to accept a gift from Zeus, as Zeus' wrath would undoubtedly also extend to the mortal race He had created.

And Zeus, indeed, was not done with His punishment. After imprisoning Prometheus, Zeus assembled the Theoi. He told Hēphaistos to fashion a woman out of water and clay. Hēphaistos did and brought the statue before Zeus. Zeus then asked Aphrodite to bless the woman with a beauteous face and feminine whiles. He asked Athena to dress her modestly and give her the ability to weave and craft, Demeter taught her to tend the garden. From Apollon, she received the ability to make music and sing. All Gods gave her treacherous gifts, including Hera, who made her curious, and Hermes, who made her cunning and quick of the tongue. Then, Zeus named her Pandôra (Πανδωρα), All-Giving, and breathed life into her. He then bade Hermes to deliver her to Epimetheus, along with a vase (pithos) Pandôra was never allowed to open.

Epimetheus had been warned by Prometheus never to open or accept a gift from Zeus, but he laid eyes on Pandôra's beauty and fell in love too deeply to reject her. He took her into his home amongst men and wedded her right away. Pandôra loved Epimetheus, because he was a good man and good husband. She worked tirelessly to please him and helped him keep the home. Yet, she found herself drawn to the pithos she was told never to open. Her eyes would wander to it constantly and Hera's gift eventually prevented her from holding to her promise.

On a day when Epimetheus was away from the home, Pandôra decided to risk a sneak peak at the contents she had fantasized about so often. She pulled the lid off of the pithos and out flew dark spirits of disease, death and the destruction of humanity. Pandôra hastened to seal the jar but managed to trap only Hope (Elpis)--by Zeus' decree or by mere accident.

Mankind was now plagued with illness, with failing crops, with all that makes life hard. But they had Hope and soon, Pyrrha (Fire) was born to Epimetheus and Pandôra. Prometheus had a son, Deukalion, with Pronoia, an Okeanid nymph of Mount Parnassos in Phokis. They lived in the time of the Bronze Race of Man, a corrupt age in which the Gods were rarely worshipped. Zeus was angered by their hubris and decided to end this race of man. He sent a great deluge, killing everyone but Deukalion and Pyrrha, who were warned of the flood by Prometheus. They did not build a boat, but clung to a chest, eventually sailing to the mountain peaks of Parnassos. 

Once Zeus caused the water to recede, Deukalion and Pyrrha travelled to the oracle of Delphi and begged to learn how they could bring back mankind. They were told that they needed to cast the bones of their mother over their shoulders, and they understood that they needed to pick up stoned and toss them, because Gaia, the earth, is everyone's mother. Where the pebbles landed, humans rose from the earth. Deukalion created the men and Pyrrha the women, and from their efforts, humankind once more arose to populate the earth.

There are more flood myths in Hellenic mythology--Philemon and Baucis, for example--but none as all-consuming as this one, sent by Zeus. This severe example acts as a warning to mankind: the ultimate display of destructive power by the Gods should mankind disobey Them. In this case, human kind was unethical, did not give to the Gods, and overstepped their bounds. Autochthonous births (αὐτός χθών, 'earth-born') are also well-known in Hellenic mythology. Many ancient Hellenic kings traced their line back to Gaia in this way. These two themes give us an ethical standard to live up to, explain our place in the universe, and connect us to the divine in a beautiful and enlightening way. These are the major reasons why I enjoy this myth so much.
