Atra-Hasis Epic — Old Babylonian Cuneiform Tablets
The Epic of Atra-Hasis is an Akkadian narrative preserved on cuneiform tablets, the oldest complete copies of which date to the Old Babylonian period, c. 1646–1626 BCE (reign of Ammi-saduqa). The text was definitively edited and translated by W.G. Lambert and A.R. Millard in their 1969 Clarendon Press monograph, which established the scholarly baseline for all subsequent comparative flood-myth work. The epic covers creation of humanity (from divine blood and clay), the overpopulation and noise problem that motivates the gods to send plagues and ultimately the flood, and the survival of the pious Atrahasis ("exceedingly wise") who is warned by Enki. It is the earliest substantially complete Mesopotamian flood narrative in cuneiform and the textual ancestor of Gilgamesh Tablet XI.
The oldest tablets are dated c. 1646–1626 BCE, pushing the attested written flood tradition approximately one thousand years before the Book of Genesis is believed to have been composed.

Utanapishti/Utnapishtim is called "Atrahasis" twice in Gilgamesh Tablet XI (lines 49 and 197), indicating direct literary dependence of the later Standard Babylonian Gilgamesh version on the Atrahasis tradition. (Originally extracted from Wikipedia: Gilgamesh flood myth; line 49 independently verified 2026-06-11 against SOAS BAPLAR's George-2003-based text — "ana bāb atar-hasīs ipahhur mā[tum]" — see Provenance; cf. epic-of-gilgamesh-tablet-xi citing George 2003, vol. 1, pp. 508–528 for both lines.)
The gods' stated motivation in Atrahasis — to "wipe out mankind" because human noise (rigmu) disturbs their sleep — is distinct from the Gilgamesh version, where the motive is left vague. This motivational specificity is one reason scholars regard Atrahasis as the earlier, fuller version. (Attributed to Lambert & Millard 1969, pp. 12–15, via tertiary summary; page reference not yet checked against the edition.)
A Sumerian precursor tradition, the Eridu Genesis (tablet CBS 10673, Nippur; c. 1600 BCE written form; Thorkild Jacobsen named and analysed it in JBL 100:4, 1981), features the flood hero Ziudsura and may represent an earlier independent branch, though the surviving tablet is no earlier than Atrahasis.
Lambert and Millard's 1969 edition is the landmark scholarly work; it is accepted across Assyriology as the standard edition. The dating of the oldest Atrahasis tablet to Ammi-saduqa's reign is based on scribal colophons; this is a well-established paleographic attribution. Uncertainty remains about whether the flood episode was originally an integral part of the creation myth or a later interpolation. Some scholars (e.g. Wilfred G. Lambert, later work) explored whether the flood narrative ultimately derives from a Sumerian original or was first composed in Akkadian — the question remains open. The Eridu Genesis tablet, also Old Babylonian in its written form, shows that Sumerian and Akkadian flood traditions were in circulation in the same period; which is "earlier" as an oral tradition cannot be determined from cuneiform evidence alone.
Provenance: This note's extractions were not taken from Lambert & Millard 1969 directly. They were drawn from tertiary summaries — Wikipedia ("Gilgamesh flood myth") and a COJS summary page — while the original frontmatter recorded the Wikipedia URL as url_verified: yes, misrepresenting a verified tertiary page as the cited scholarly source. Corrected: the Lambert & Millard citation stands as the reference edition (url_verified: not-online); per AGENTS §2.4, claims resting solely on this note's tertiary-derived extractions are capped at medium.
