Diluvian

A flood myth or deluge myth is a narrative in which a great flood, usually sent by a deity or deities, destroys civilization, often in an act of divine retribution. Parallels are often drawn between the flood waters of these myths and the primeval waters found in certain creation myths, as the flood waters are described as a measure for the cleansing of humanity, in preparation for rebirth. Most flood myths also contain a culture hero, who "represents the human craving for life".

The flood myth motif is found among many cultures as seen in the Mesopotamian flood stories, Deucalion in Greek mythology, the Genesis flood narrative, the Hindu texts from India, Bergelmir in Norse Mythology, in the lore of the K'iche' and Maya peoples in Mesoamerica, the Lac Courte Oreilles Ojibwa tribe of Native Americans in North America, the Muisca, and Cañari Confederation, in South America, and the Aboriginal tribes in southern Australia.

The Mesopotamian flood stories concern the epics of Ziusudra, Gilgamesh, and Atrahasis. In the Sumerian King List, it relies on the flood motif to divide its history into preflood (antediluvian) and postflood periods. The preflood kings had enormous lifespans, whereas postflood lifespans were much reduced. The Sumerian flood myth found in the Deluge tablet was the epic of Ziusudra, who heard the Divine Counsel plan to destroy humanity, in response to which he constructed a vessel that delivered him from great waters. In the Atrahasis version, the flood is a river flood.
