Forgotten, but not erased
The Sumerians were not forgotten in the sense of vanishing without a trace. Their religion, literature and writing system shaped Babylonian and Assyrian culture, and Sumerian continued to be copied and studied by scribes for well over a thousand years after it stopped being spoken in daily life. What faded was general knowledge of them as a distinct people. By the Hellenistic and Roman periods, classical authors wrote about Babylon and Assyria, and not about Sumer. The name “Sumer” and the idea of a Sumerian people were lost to the wider world for roughly two thousand years, until scholars of the 19th century pieced them together again.
Why memory faded
Several things happened. Sumerian ceased to be a spoken language around 2000 to 1800 BCE and survived only as a language of ritual and scholarship. Cities such as Ur and Eridu declined as rivers shifted and political power moved north to Babylon and Assyria. Cuneiform itself fell out of use during the first centuries CE. Greek and Roman writers, and later Biblical traditions, kept memory of Babylon and Nineveh alive but gave little hint of an older civilization in the south. The ruins sat as large mounds, known locally by Arabic names, and nobody could read the inscriptions in them.
Decipherment: from Behistun to Nineveh
The first step was reading cuneiform at all. In the 1830s and 1840s Henry Rawlinson copied the trilingual Behistun inscription in Iran, which carried the same text in Old Persian, Elamite and Babylonian, and he, Edward Hincks and others used it to make progress on the Babylonian version. Their work did for cuneiform something loosely comparable to what the Rosetta Stone had done for Egyptian, though the process took decades and involved many scholars.
Meanwhile, excavations at Nineveh brought thousands of tablets from the library of the Assyrian king Ashurbanipal to the British Museum. Among them were word lists and texts in two columns, with a language that looked unrelated to Akkadian alongside its Akkadian translation. This was Sumerian, preserved by Assyrian scribes as a learned language.
Scholars argued over what this language was. Some, such as Joseph Halévy, doubted that it was a real language at all and suggested it was a cryptic way of writing Akkadian. Others, including Edward Hincks and Jules Oppert, argued for a separate non-Semitic people. In 1869 Oppert proposed the name “Sumerian”, drawn from the ancient royal title “king of Sumer and Akkad”. The debate continued for years, and it was the accumulation of new texts that eventually settled it.
Telloh and the first direct finds
The first large discoveries of Sumerian-period remains came from Telloh, the ancient city of Girsu in the state of Lagash. Ernest de Sarzec, a French vice-consul in Basra, began excavating there in 1877. He found statues of Gudea, the ruler of Lagash around 2100 BCE, and thousands of cuneiform tablets and inscribed objects. The statues were carved of hard stone and inscribed in Sumerian, and they showed that a sophisticated Sumerian culture had existed well before Babylon. Digging continued at Telloh in several campaigns over later decades. Methods of the time were rough by modern standards, and some finds were looted or poorly recorded, which limits what can be reconstructed today.
Nippur, Ur and the age of large expeditions
At Nippur, an American team from the University of Pennsylvania began work in 1889. Over several seasons they uncovered large numbers of tablets, including school texts, hymns and literary works, in the ancient religious centre of Sumer. The expedition faced disease, conflict and disputes among its staff, and its early record keeping is uneven, but it produced the largest early body of Sumerian literary material. These tablets, later studied by scholars such as Arno Poebel, who published a Sumerian grammar in the 1920s, and Samuel Noah Kramer, whose work on translating and interpreting Sumerian literature began in the 1930s, helped establish Sumerian as a language and literature in its own right.
Leonard Woolley’s excavations at Ur, from 1922 to 1934, offered a very different kind of evidence. Woolley’s team uncovered the great ziggurat precinct, residential neighbourhoods and the Royal Cemetery, with its gold, lapis lazuli and lyres. Woolley’s interpretations of some finds, notably his picture of the graves, were influential but have since been reconsidered. Meanwhile, work at sites such as Kish, Uruk and Tell Asmar widened the picture.
Methods improve
Over the 20th century, Mesopotamian archaeology shifted from treasure hunting to careful recording. Excavators learned to track layers in mounds, a technique linked to tell stratigraphy, and later scientific dating, including radiocarbon dating, gave firmer chronological anchors, although many Sumerian dates still rest mainly on texts and king lists. Surveys of ancient canals and settlement patterns, beginning in the mid-20th century, helped scholars see how cities fitted into their landscape.
Language work advanced alongside. Sumerian is not related to any known language, so understanding it depended on bilingual lists, patterns in the texts and comparison with Akkadian. Many details of grammar and vocabulary are still debated, particularly for the earliest texts.
What is still being recovered
Recovery of Sumer is ongoing. Tens of thousands of tablets remain unpublished in museum collections, and many sites in Iraq have suffered looting, war damage and neglect, which has destroyed context and information. New excavations and digital cataloguing projects continue to add detail. The Sumerians are no longer lost, but our knowledge of them is still partial, and it is built on a patchwork of finds made over roughly 150 years.
