Sumerian literature constitutes the earliest known corpus of recorded literature, including the religious writings and other traditional stories maintained by the Sumerian civilization and largely preserved by the later Akkadian and Babylonian empires. These records were written in the Sumerian language in the 18th and 17th centuries BC during the Middle Bronze Age.
The Sumerians invented one of the first writing systems, developing Sumerian cuneiform writing out of earlier proto-writing systems by about the 30th century BC.
The Sumerian language remained in official and literary use in the Akkadian and Babylonian empires, even after the spoken language disappeared from the population; literacy was widespread, and the Sumerian texts that students copied heavily influenced later Babylonian literature.
Most Sumerian literature is written in left-justified lines, and could contain line-based organization such as the couplet or the stanza, but the Sumerian definition of poetry is unknown. It is not rhymed, although “comparable effects were sometimes exploited.” It did not use syllabo-tonic versification, and the writing system precludes detection of rhythm, metre, rhyme, or alliteration. Quantitative analysis of other possible poetic features seems to be lacking, or has been intentionally hidden by the scribes who recorded the writing.
Types of literature were not clearly defined, and all Sumerian literature incorporated poetic aspects. Sumerian poems demonstrate basic elements of poetry, including lines, , and metaphor. Humans, gods, talking animals, and inanimate objects were all incorporated as characters. Suspense and humor were both incorporated into Sumerian stories. These stories were primarily shared orally, though they were also recorded by scribes. Some works were associated with specific musical instruments or contexts and may have been performed in specific settings. Sumerian literature did not use titles, instead being referred to by the work's first line.
