The Debate between Winter and Summer or Myth of Emesh and Enten is a Sumerian creation myth, written on clay tablets in the mid to late 3rd millennium BC.
Seven "debate" topics are known from the Sumerian literature, falling in the category of 'disputations'; some examples are: the debate between sheep and grain; the debate between bird and fish; the tree and the reed; and the dispute between silver and copper, etc. These topics came some centuries after writing was established in Sumerian Mesopotamia. The debates are philosophical and address humanity's place in the world.
The first lines of the myth were discovered on the University of Pennsylvania Museum of Archaeology and Anthropology, catalogue of the Babylonian section (CBS), tablet number 8310 from their excavations at the temple library at Nippur. This was translated by George Aaron Barton in 1918 and first published as "Sumerian religious texts" in "Miscellaneous Babylonian Inscriptions", number seven, entitled "A Hymn to Ibbi-Sin". The tablet is 5.5 inches (14 cm) by 4.75 inches (12.1 cm) by 1.6 inches (4.1 cm) at its thickest point. Barton describes Ibbi-Sin as an "inglorious King" suggesting the text to have been composed during his lifetime, he commented "The hymn provides a powerful statement for emperor worship in Ur at the time of composition." Ibbi-Sin is still mentioned in the modern translation "For my king named by Nanna, the son of Enlil, Ibbi-Sin, when he is arrayed in the 'cutur' garment and the 'hursag' garment."
