Above and beyond any particular cultural or geographic bias, floods are representative of fertility. The pounding of waves in the world's oceans has, often enough, been a metaphor for the seed of man, the sperm that fertilizes the eggs of women. When the waters inundate the shores, they leave in their wake green and growing things, vegetation to nourish all animal life – yup, that includes we humans, too.
Another metaphor a flood represents is cleansing, both universal and spiritual. The reason a child is baptized is to perform a spiritual cleansing having been born from that mundane union of male and female. For an adult, a baptism represents rebirth into a new religion…a washing-away of the old beliefs.
Finally, floods are a type of transportation from the mundane world to the spiritual world, and a rebirth into that world of spirit. Crossing the water and crossing the sky were the same thing to the ancient Egyptians who crossed the Nile to bury the bodies of the kings/ pharaohs. This journey across the Nile was symbolic of the journey the spirit took across the Milky Way (which was considered to be a celestial river) to arrive in the land of the dead ruled by Osiris. Another water-as-spiritual-travel tradition is found in the I Ching. The Book of Changes often mentions "crossing the great river" or "crossing the great water" when it speaks of a spiritual journey.
One of the surprising threads that connects many of the world's flood myths is the number of diverse cultures whose ancestors, as well as a variety of plant and animal life, were saved by fashioning a boat of some sort. It's quite remarkable, really, from Asia to South America, people saved themselves by building boats. Apparently, Noah isn't the only one who got a message to learn ship-building in short order.
There are hundreds of flood myths from around the world. A great many of them are caused by a god's decision to punish sinful humans. In a few cases, the flood is a god's attempt to save the earth due to overpopulation. Overwhelmingly, no matter the reason for the flood, the outcome is that the world is fresh and new again, and people have the chance to start over.
Perhaps people today have been "missing the boat!" People put the emphasis on the wrong part of the story; instead of talking about wickedness and punishment, we should concentrate on being refreshed, being reborn, and starting over!
Here are flood myths from around the globe. Check out the last one from South Brazil…it gives a whole new spin on Darwin and his Theory of Evolution!
European:
Greek: Zeus sent a flood to destroy the men of the Bronze Age. Prometheus advised his son Deucalion to build a chest. All other men perished except for a few who escaped to high mountains. Deucalion and his wife Pyrrha (daughter of Epimetheus and Pandora), after floating in the chest for nine days and nights, landed on Parnassus. When the rains ceased, he sacrificed to Zeus, the God of Escape. At the bidding of Zeus, he threw stones over his head; they became men, and the stones which Pyrrha threw became women. That is why people are called laoi, from laas, "a stone." (The Roman story is very similar.)
Celtic: Heaven and Earth were great giants, and Heaven lay upon the Earth so that their children were crowded between them, and the children and their mother were unhappy in the darkness. The boldest of the sons led his brothers in cutting up Heaven into many pieces. From his skull they made the firmament. His spilling blood caused a great flood which killed all humans except a single pair, who were saved in a ship made by a beneficent Titan.
Welsh: The lake of Llion burst, flooding all lands. Dwyfan and Dwyfach escaped in a mastless ship with pairs of every sort of living creature. They landed in Prydain (Britain) and repopulated the world.
Lithuanian: From his heavenly window, the supreme god Pramzimas saw nothing but war and injustice among mankind. He sent two giants, Wandu and Wejas (water and wind), to destroy earth. After twenty days and nights, little was left. Pramzimas looked to see the progress. He happened to be eating nuts at the time, and he threw down the shells. One happened to land on the peak of the tallest mountain, where some people and animals had sought refuge. Everybody climbed in and survived the flood floating in the nutshell. God's wrath abated, he ordered the wind and water to abate. The people dispersed, except for one elderly couple who stayed where they landed. To comfort them, God sent the rainbow and advised them to jump over the bones of the earth nine times. They did so, and up sprang nine other couples, from which the nine Lithuanian tribes descended.
Transylvanian Gypsy: One day, and old man came to the country and asked for a night's lodging, which a couple gave him in their cottage. When he departed the next day, he said he would return in nine days. He gave his host a small fish in a vessel and said he would reward the host if he did not eat the fish but returned it then. The wife thought the fish must be exceptionally good to eat, but the husband said he had promised the old man to keep it and made the woman swear not to eat it. After two days of thinking about it, though, the wife yielded to temptation and threw the fish on the hot coals. Immediately, she was struck dead by lightning, and it began to rain. The rivers started overflowing the country. On the ninth day, the old man returned and told his host that all living things would be drowned, but since he had kept his oath, he would be saved. The old man told the host to take a wife, gather his kinfolk, and build a boat on which to save them, animals, and seeds of trees and herbs. The man did all this. It rained a year, and the waters covered everything. After a year, the waters sank, and the people and animals disembarked.
Near East
Sumerian: The gods had decided to destroy mankind. The god Enlil warned the priest-king Ziusudra ("Long of Life") of the coming flood by speaking to a wall while Ziusudra listened at the side. He was instructed to build a great ship and carry beasts and birds upon it. Violent winds came, and a flood of rain covered the earth for seven days and nights. Then Ziusudra opened a window in the large boat, allowing sunlight to enter, and he prostrated himself before the sun-god Utu. After landing, he sacrificed a sheep and an ox and bowed before Anu and Enlil. For protecting the animals and the seed of mankind, he was granted eternal life and taken to the country of Dilmun, where the sun rises.
Babylonian: Three times (every 1200 years), the gods were distressed by the disturbance from human overpopulation. The gods dealt with the problem first by plague, then by famine. Both times, the god Enki advised men to bribe the god causing the problem. The third time, Enlil advised the gods to destroy all humans with a flood, but Enki had Atrahasis build an ark and so escape. Also on the boat were cattle, wild animals and birds, and Atrahasis' family. (The Assyrian version is very similar.)
Chaldean: The god Chronos in a vision warned Xisuthrus, the tenth king of Babylon, of a flood coming on the fifteenth day of the month of Daesius. The god ordered him to write a history and bury it in Sippara, and told him to build and provision a vessel (5 stadia by 2 stadia) for himself, his friends and relations, and all kinds of animals. Xisuthrus asked where he should sail, and Chronos answered, "to the gods, but first pray for all good things to men." Xisuthrus built a ship five furlongs by two furlongs and loaded it as ordered. After the flood had come and abated somewhat, he sent out some birds, which returned. Later, he tried again, and the birds returned with mud on their feet. On the third trial, the birds didn't return. He saw that land had appeared above the waters, so he parted some seams of his ship, saw the shore, and drove his ship aground in the Corcyraean mountains in Armenia. He disembarked with his wife, daughter, and pilot, and offered sacrifices to the gods. Those four were translated to live with the gods.
Hebrew: God, upset at mankind's wickedness, resolved to destroy it, but Noah was righteous and found favor with Him. God told Noah to build an ark. Noah did so, and took aboard his family and pairs of all kinds of animals. For 40 days and nights, floodwaters came from the heavens and from the deeps, until the highest mountains were covered. The waters flooded the earth for 150 days; then God sent a wind and the waters receded, and the ark came to rest in Ararat. After 40 days, Noah sent out a raven, which kept flying until the waters had dried up. He next sent out a dove, which returned without finding a perch. A week later he set out the dove again, and it returned with an olive leaf. The next week, the dove didn't return. After a year and 10 days from the start of the flood, everyone and everything emerged from the ark. Noah sacrificed some clean animals and birds to God, and God, pleased with this, promised never again to destroy all living creatures with a flood, giving the rainbow as a sign of this covenant. Animals became wild and became suitable food, and Noah and his family were told to repopulate the earth.
Africa
Pygmy: Chameleon heard a strange noise, like water running, in a tree, but at that time there was no water in the world. He cut open the trunk, and water came out in a great flood that spread all over the earth. The first human couple emerged with the water.
Bakongo (west Zaire): An old lady, weary and covered with sores, arrived in a town called Sonanzenzi and sought hospitality, which was denied her at all homes but the last she came to. When she was well and ready to depart, she told her friends to pack up and leave with her, as the place was accursed and would be destroyed by Nzambi. The night after they had left, heavy rains came and turned the valley into a lake, drowning all the inhabitants of the town. The sticks of the houses can still be seen deep in the lake.
Yoruba (southwest Nigeria): A god, Ifa, tired of living on earth and went to dwell in the firmament with Obatala. Without his assistance, mankind couldn't interpret the desires of the gods, and one god, Olokun, in a fit of rage, destroyed nearly everybody in a great flood.
Mandingo (Ivory Coast): A charitable man gave away everything he had to the animals. His family deserted him, but when he gave his last meal to the (unrecognized) god Ouende, Ouende rewarded him with three handfuls of flour which renewed itself and produced even greater riches. Then Ouende advised him to leave the area, and sent six months of rain to destroy his selfish neighbors. The descendants of the rich man became the present human race.
Asia
Yenisey-Ostyak (north central Siberia): Flood waters rose for seven days. Some people and animals were saved by climbing on floating logs and rafters. A strong north wind blew for seven days and scattered the people, which is why there are now different peoples speaking different languages.
Tuvinian (Soyot) (north of Mongolia): The giant frog (or turtle) which supported the earth moved, which caused the cosmic ocean to begin flooding the earth. An old man who had guessed something like this would happen built an iron-reinforced raft, boarded it with his family, and was saved. When the waters receded, the raft was left on a high wooded mountain, where, it is said, it remains today. After the flood, Kezer-Tshingis-Kaira-Khan created everything around us.
Hindu: Manu, the first human, found a small fish in his washwater. The fish begged protection from the larger fishes, in return for which it would save Manu. Manu kept the fish safe, transferring it to larger and larger reservoirs as it grew, eventually taking it to the ocean. The fish warned Manu of a coming deluge and told him to build a ship. When the flood rose, the fish came, and Manu tied the craft to its horn. The fish led him to a northern mountain and told Manu to tie the ship's rope to a tree to prevent it from drifting. Manu, alone of all creatures, survived. He made offerings of clarified butter, sour milk, whey, and curds. From these, a woman arose, calling herself Manu's daughter. Whatever blessings he invoked through her were granted him. Through her, he generated this race.
Tibet: Tibet was almost totally inundated, until the god Gya took compassion on the survivors, drew off the waters through Bengal, and sent teachers to civilize the people, who until then had been little better than monkeys. Those people repopulated the land.
Lolo (southwestern China): In primeval times, men were wicked. The patriarch Tse-gu-dzih sent a messenger down to earth, asking for some flesh and blood from a mortal. Only one man, Du-mu, complied. In wrath, Tse-gu-dzih locked the rain-gates, and the waters mounted to the sky. Du-mu was saved in a log hollowed out of a Pieris tree, together with his four sons and otters, wild ducks, and lampreys. The civilized peoples who can write are descended from the sons; the ignorant races are descendants of wooden figures whom Du-mu constructed after the deluge.
Miao (Hmong) (southern China, north Thailand, Laos): After people had lived on the earth for 9,000 years, two brothers noticed that someone was coming at night and undoing everything they had done in the field in the day. They laid in wait and saw an old man filling their furrows. The elder brother wanted to kill him, but the younger brother said they should first question him for his reason. The old man said their work was futile because a flood would soon come. The brothers realized the man was the Lord of the Sky and asked him what they should do. He told the elder, violent-tempered brother to build an iron boat and the younger brother to build a wooden boat and to take his sister, males and females of each animal species, and two seeds of each species of plant. In the seventh month rain fell for four days and nights. The iron boat sank, but the wooden boat floated up to the sky. Seeing the earth flooded, the Lord of the Sky sent a dragon in the shape of a rainbow to dry it. The brother wanted to marry his sister, but she resisted. But after various tests proved it was the will of the Lord of the Sky, they married. Their child had no head or limbs. Thinking it was an egg, they cut it open. It contained no child, but the pieces became people when they fell to earth. By cutting it into the smallest possible pieces, they created innumerable children and repopulated the earth.
Australia
Narrinyeri (South Australia): A man's two wives ran away from him. He pursued them to Encounter Bay, saw them at a distance, and angrily cried out for the waters to rise and drown them. A terrible flood washed over the hills and killed the two women. The waters rose so high that a man named Nepelle, who lived at Rauwoke, had to drag his canoe to the top of the hill now called Point Macleay. The dense part of the Milky Way shows his canoe floating in the sky.
Victoria: Bunjil, the creator, was angry with people because of the evil they did, so he caused the ocean to flood by urinating into it. All people were destroyed except those whom Bunjil loved and fixed as stars in the sky, and a man and a woman who climbed a tall tree on a mountain, and from whom the present human race is descended.
North, Central, and South America
Norton Sound Eskimo: In the first days, the water from the sea came up and flooded all the earth except for a very high mountain in the middle. A few animals escaped to this mountain, and a few people survived in a boat, subsisting on fish. The people landed on the mountain as the water subsided and followed the retreating water to the coast. The animals also descended.
Kaska (northern inland British Columbia): A great flood came; people survived it on rafts and canoes. Darkness and high winds came, which scattered the vessels. When the flood subsided, people landed at the nearest land and lived where they had landed. Thus they were scattered all over the world, and when they met again long afterwards, they were different tribes and spoke different languages.
Shasta (northern California interior): Coyote encountered an evil water spirit who said, "There is no wood" and caused water to rise until it covered Coyote. After the water receded, Coyote shot the water spirit with a bow and ran away, but the water followed him. He ran to the top of Mount Shasta; the water followed but didn't quite reach the top. Coyote made a fire, and all the other animal people swam to it and found refuge there. After the water receded, they came down, made new homes, and became the ancestors of all the animal people today.
Michoacan (Mexico): When the flood waters began to rise, a man named Tezpi entered into a great vessel, taking with him his wife and children and diverse seeds and animals. When the waters abated, the man sent out a vulture, but the bird found plenty of corpses to eat and didn't return. Other birds also flew away and didn't return. Finally, he sent out a hummingbird, which returned with a green bough in its beak.
Macusi (British Guyana): The good spirit Makunaima ("He who works in the night") created the heaven and earth. When he had created plants and trees, he came down from his heavenly mansion, climbed a tree, and chipped off bark with a large stone axe. The chips turned into animals of all kinds when they fell into the river at the base of the tree. Next, Makunaima created man, and after the man had fallen asleep, he awoke to find a woman beside him. Later the evil spirit got more power on earth, so Makunaima sent a great flood. Only one man survived in a canoe. He sent a rat to see whether the flood had abated, and the rat returned with a cob of maize. When the flood had subsided, the man threw stones behind him, which became other people.
Coroado (south Brazil): A flood once covered the whole earth except for the top of the coastal range Serra do Mar. Members of the three tribes Coroados, Cayurucres, and Cames, swam for the mountains holding lighted torches between their teeth. The Cayurucres and Cames wearied and drowned, and their souls went to dwell in the heart of the mountain. The Coroados made it and stayed there, some on the ground and some in the branches of trees. Several days passed without food and without the water lowering. Then some saracuras, a species of waterfowl, flew to them with baskets of earth. The birds began throwing the earth into the water, and the water sank. The people urged the birds to hurry, so the birds called the ducks to help them. When the flood subsided, the Coroados descended, except for the ones which had climbed into trees, who became monkeys.
