Focus On: (53311) Deucalion

Deukalion, along with his wife Pyrrha, daughter of Pandora, lived in the northern reaches of Greece. Zeus, angered by the impiety of humankind at the time, sent the Great Deluge. Prometheus warned Deukalion and Pyrrha of the impending apocalypse and they survived by mounting a chest and reaching the dry peaks of Mount Parnassos. Once the waters receded, the couple consulted the Delphic Oracle on how to repopulate the earth.
