deluge myth

"The Deluge", frontispiece to Gustave Doré's illustrated edition of the Bible A flood myth or a deluge myth is a narrative in which a great flood—usually sent by one or more deities—destroys civilization, typically as an act of divine retribution. Parallels are often drawn between the floodwaters of these myths and the primordial cosmic ocean that appears in certain creation myths, because the floodwaters are described as a means of social cleansing or purifying humanity of its corruption, for example, in preparation for rebirth. Most flood myths also feature a culture hero who "represents the human craving for life".

The oldest known narrative of a divinely initiated flood originates from the Sumerian culture in Mesopotamia, among others expressed in the Akkadian Atra-Hasis epic, which dates to the 18th century BCE. Comparable flood narratives appear in many other cultures, including the biblical Genesis flood narrative, manvantara-sandhya in Hinduism, Deucalion in Greek mythology, and in indigenous North American cultures.
