What is "ziusudra"

Ziusudra (also Zi-ud-sura and Zin-Suddu; Hellenized Xisuthros: "found long life" or "life of long days") of Shuruppak is listed in the WB-62 Sumerian king list recension as the last king of Sumer prior to the deluge. He is subsequently recorded as the hero of the Sumerian flood epic. He is also mentioned in other ancient literature, including The Death of Gilgamesh and The Poem of Early Rulers, and a late version of The Instructions of Shuruppak refers to Ziusudra. Akkadian Atrahasis ("extremely wise") and Utnapishtim ("he found life"), as well as biblical Noah ("rest") are similar heroes of flood legends of the ancient Near East.

Although each version of the flood myth has distinctive story elements, there are numerous story elements that are common to two, three, or four versions. The earliest version of the flood myth is preserved fragmentarily in the Eridu Genesis, written in Sumerian cuneiform and dating to the 17th century BC, during the 1st Dynasty of Babylon when the language of writing and administration was still Sumerian. Strong parallels are notable with other Near Eastern flood legends, such as the biblical account of Noah.
