Eridu Genesis / Sumerian Flood Story (Ziusudra tablet)
The only surviving Sumerian-language flood narrative: a single fragmentary tablet from Nippur (CBS 10673, c. 1600 BCE) in which the gods decree the deluge, the pious king Ziusudra of Šuruppak is warned (by Enki, through a wall), survives in a boat, sacrifices, and is granted eternal life in Dilmun. Jacobsen's article names and frames the composition; Civil's edition is the philological standard. It anchors the question of whether the flood story is originally Sumerian (with Akkadian Atra-ḫasīs as adaptation) or a parallel OB-era literary product.
The hero Ziusudra ("Life of long days") corresponds to Akkadian Ūta-napišti and to Berossus's Xisouthros — one continuous onomastic chain across ~2,000 years of the tradition.
The tablet is roughly contemporary with the OB Atra-ḫasīs copies; the Sumerian text is therefore not demonstrably older as an attestation, despite the language being older (Civil in Lambert & Millard 1969, 138–140).
The Sumerian King List (OB recensions, c. 1900–1800 BCE) divides history at "the Flood" ("after the flood had swept over, kingship was lowered from heaven a second time") — the earliest dated allusion to the flood as a past epochal event, predating all surviving narratives.
Single-tablet attestation with large lacunae; Jacobsen's "Eridu Genesis" reconstruction stitches it together with other compositions and is contested as a unity. Civil suspected the Sumerian text may itself be a late scribal exercise dependent on the Akkadian tradition — so "Sumerian original → Akkadian copy" cannot be assumed. The Ur III (c. 2100 BCE) King List recension appears to lack the antediluvian/flood section, so the flood-allusion date rests on OB copies.
