The oldest known flood myth is the Sumerian flood story, preserved in a fragmentary clay tablet from the city of Nippur, dated to around 1600 BCE. This text, known as the Eridu Genesis, tells of a king named Ziusudra who is warned by a deity of a coming deluge and builds a boat to survive it.
The Sumerian Eridu Genesis
The Eridu Genesis is the earliest surviving written account of a great flood. It was discovered in the late 19th century among the ruins of Nippur in modern-day Iraq. The tablet is broken, but the surviving text describes how the gods decide to destroy humanity with a flood. The god Enki, who is sympathetic to humans, warns Ziusudra, the pious king of Shuruppak, to build a large boat. Ziusudra does so, and after the floodwaters recede, he offers a sacrifice to the gods. The sun god Utu appears, and Ziusudra is granted eternal life and made to dwell in the land of Dilmun.
This story predates the more famous Babylonian flood myth in the Epic of Gilgamesh by several centuries. The Gilgamesh tablet containing the flood story (Tablet XI) dates to around 650 BCE, though the epic itself is older. The Sumerian version is the earliest written flood narrative we have, but it is not the oldest flood story in the world—that distinction likely belongs to oral traditions that were never written down.
How the Sumerian Myth Was Passed Down
The Sumerian flood story was transmitted through cuneiform writing on clay tablets. Scribes in ancient Mesopotamia copied and adapted texts over centuries. The Eridu Genesis we have today is a copy made in the Old Babylonian period, but the story it tells is much older. It likely originated as an oral tale in the third millennium BCE, passed down by word of mouth before being written.
When the Sumerians were conquered by the Babylonians, their myths were absorbed and adapted. The Babylonian version, found in the Epic of Gilgamesh, changes the hero’s name to Utnapishtim and adds more detail about the boat’s construction and the animals taken aboard. Later, the Assyrians copied the Babylonian texts, and through them, the story influenced neighboring cultures, including the Hebrews, who wrote the Noah story in the Book of Genesis.
Key Differences Between the Sumerian and Later Versions
While the Sumerian, Babylonian, and Hebrew flood stories share a common outline—a divine warning, a boat, a flood, and a sacrifice—they differ in important ways:
- Number of gods: The Sumerian version has multiple gods who disagree about the flood. The Hebrew version has a single God who acts alone.
- Reason for the flood: In the Sumerian story, the gods send the flood because humans are too noisy. In the Babylonian version, the god Enlil is angry at humans for disturbing his rest. In the Hebrew version, God sends the flood because of human wickedness.
- Hero’s fate: Ziusudra is granted immortality and taken to Dilmun. Utnapishtim is also made immortal, but Noah lives out his life and dies naturally.
- Duration: The Sumerian text is too broken to know the exact length, but the Babylonian flood lasts seven days. The Hebrew flood lasts forty days and nights.
These differences show how each culture reshaped the older myth to fit its own religious beliefs and literary traditions.
What the Eridu Genesis Tells Us About Sumerian Religion
The Eridu Genesis offers a rare glimpse into Sumerian theology. The gods are not all-powerful or all-good; they are capricious and can be irritated by human behavior. The flood is not a moral punishment but a divine whim. The hero Ziusudra is chosen not because he is righteous, but because the god Enki favors him and warns him directly.
The story also reflects the Sumerian view of kingship. Ziusudra is a king, and his survival ensures the continuation of royal authority. The text ends with his being given eternal life, which legitimizes the institution of kingship as a divine gift. This political dimension is absent from the later Hebrew version, where Noah is a farmer, not a king.
Comparisons with Other Ancient Flood Myths
Beyond Mesopotamia, flood myths appear in nearly every ancient culture. The Greeks told of Deucalion and Pyrrha, who survived a flood sent by Zeus and repopulated the earth by throwing stones over their shoulders. In Hindu tradition, the god Vishnu appears as a fish (Matsya) to warn King Manu of an impending flood, and Manu builds a boat that is tied to the fish’s horn. In Chinese mythology, the hero Yu tamed the great flood by dredging rivers, rather than building an ark.
These stories are so widespread that some scholars argue they may be distant memories of real flooding events, such as the flooding of the Black Sea around 5600 BCE or the Persian Gulf around 6000 BCE. However, no single event can explain all flood myths, and most scholars now believe they developed independently in different regions, drawing on common human experiences of rivers overflowing and coastal storms.
Common Misconceptions About the Oldest Flood Myth
One common misconception is that the Epic of Gilgamesh contains the oldest flood story. In fact, the Gilgamesh version is a later adaptation of the Sumerian tale. Another misconception is that the biblical Noah story is the original, with all others being copies. In reality, the Sumerian text is older than the Book of Genesis by at least a thousand years.
It is also often said that the Sumerian story is the source of all later flood myths. This is not true. While the Babylonian and Hebrew versions clearly descend from the Sumerian, Greek, Indian, and Chinese flood stories likely developed independently. The similarities between them are due to shared human psychology and environmental factors, not direct borrowing.
How to Learn More About the Eridu Genesis
If you want to read the Eridu Genesis for yourself, the best resource is a translation by Thorkild Jacobsen, published in The Harps That Once…: Sumerian Poetry in Translation (1987). The tablet itself is housed in the University Museum in Philadelphia. Online, you can find the text at the Electronic Text Corpus of Sumerian Literature (ETCSL), which offers transliterations and translations of Sumerian texts.
For a broader look at flood myths, the book The Flood Myth (1988), edited by Alan Dundes, collects essays from various scholars. It is a good starting point for understanding how flood stories function in different cultures.
Frequently Asked Questions
Is the Sumerian flood myth the oldest in the world?
It is the oldest written flood myth we have, but oral traditions may be older. The Sumerian tablet dates to about 1600 BCE, but the story itself is likely from the third millennium BCE. We cannot know if earlier oral versions existed in other cultures.
How is the Sumerian flood story different from Noah’s Ark?
The Sumerian version is polytheistic, with gods who argue and act selfishly. The hero Ziusudra is a king, not a righteous man. The Hebrew version is monotheistic, and Noah is chosen for his moral virtue. The boat is also described differently—Ziusudra’s is a square box, while Noah’s is a rectangular ark.
Did the Sumerians believe the flood actually happened?
We do not know. The story is presented as a myth, not a historical account. Some scholars think it may have been inspired by real river floods in Mesopotamia, but there is no evidence that a global flood ever occurred.
What happened to Ziusudra after the flood?
According to the Eridu Genesis, Ziusudra was given eternal life and taken to the land of Dilmun, a place often associated with paradise. The text is broken, so we do not know the full details, but later Babylonian versions say Utnapishtim and his wife were granted immortality and settled at the mouth of the rivers.
Why do so many cultures have flood myths?
Flood myths are common because floods are universal human experiences. Rivers overflow, storms cause surges, and coastal areas are vulnerable. Ancient people often interpreted these disasters as divine punishment. The similarity of many stories may also be due to cultural contact, especially in the Middle East, where trade and conquest spread ideas.
