Deucalion isn't the only guy from the land of mythology who built a boat to escape a god-sent flood that destroyed all of humanity. But he is part of a very exclusive club of human beings who survived this major disaster in order to get humanity going again after everything dried out. Thanks, guys.
Yep. You're not the only one who noticed that the story of Deucalion is a whole lot like the story of Noah, which appears in Jewish, Christian, and Islamic traditions. Just like Deucalion, Noah was the only good dude left on Earth, so when God decided to cleanse the world with a giant flood, he ordered Noah to build a giant ark. Noah brought his wife with him and ended up landing on the top of a mountain—sound familiar? Unlike Deucalion, Noah was told to bring two of every animal on earth. (We guess Zeus wasn't much of an animal lover.)
Here's yet another guy who built a boat to survive a big ol' flood. His story pops up in the ancient Sumerian Epic of Gilgamesh, where he meets Gilgamesh while the warrior king is on his quest for immortality. Like Noah, Utnapishtim was also instructed to save the animals as well as certain humans. Unlike his other boat buddies, Utnapishtim got the added bonus of immortality for his efforts.
Manu is a major figure in Hinduism and is thought of as the father of all humanity. Just like the rest of the dudes in this group, Manu was a really good guy who survived the great flood by building a gigantic boat, taking his family and some animals along with him. The gods knew that Manu was worth saving because he made the very good decision of helping out Vishnu when the god appeared to Manu in the form of a carp. (Moral of the story: always be nice to carp.)
