According to Greek mythology, Zeus once sent a flood to destroy the human race, which had angered him with their impiety. But Deucalion and Pyrrha managed to survive the flood by building a wooden chest and floating in it.
As the waters ebbed, Deucalion and Pyrrha were instructed to repopulate the earth by throwing stones over their shoulders, which were magically transformed into a new race of human beings.
Deucalion and Pyrrha were important genealogical figures in Greek myth, both as creators of the new human race and as parents of several important children—most notably Hellen, the ancestor of the Hellenes. Deucalion was said to have built the temple of Olympian Zeus in Athens. He was also connected with sites in Thessaly and Locris.
