Dynasty of Dunnum

The Dynasty of Dunnum, sometimes called the Theogony of Dunnum or Dunnu or the Harab Myth, is an ancient Mesopotamian mythical tale of successive generations of gods who take power through parricide and live incestuously with their mothers and/or sisters, until, according to a reconstruction of the broken text, more acceptable behavior prevailed with the last generation of gods, Enlil and his twin sons Nušku and Ninurta, who share rule amicably. It is extant in a sole-surviving late Babylonian copy excavated from the site of the ancient city of Sippar by Hormuzd Rassam in the 19th century.
