Deucalion is a figure from Greek mythology, often considered the Greek equivalent of Noah from the biblical flood story. He was the son of Prometheus and is known for surviving a great flood sent by the gods to cleanse the earth of humanity's wickedness. Deucalion built an ark to save himself and his wife, Pyrrha, from the deluge. After the flood, Deucalion and Pyrrha repopulated the earth by throwing stones over their shoulders, which transformed into people. This act symbolizes rebirth and the continuation of humanity. Their story highlights themes of survival, divine retribution, and renewal in ancient Greek culture.
