The YPM BC 018686 tablet is preserved in excellent condition and contains almost one fourth of "inanna's Descent" in its ninety lines of translated text. This artifact was initially noticed by Edward Chiera, a Sumerian scholar, but wouldn't be published until many years later. In 1950, Samuel N. Kramer, a well-known Sumerian scholar, published his translation of YPM BC 018686 (formerly YBC 4621) in a revised translation of "Inanna's Descent." This publication also contained the first translation of a tablet named Ni 9685, a small clay tablet artifact that provided twenty-six more translated lines of "Inanna's Descent."
Significance for the ending of "Inanna's Descent"
YPM BC 018686 was an extremely important artifact for the decipherment of the conclusion of "Inanna's Descent to the Netherworld." Another Sumerian scholar, Bendt Alster, published an article in Acta Sumerologica (volume 18, 1996) where he reconstructed the last fifty lines of "Inanna's Descent" by primarily comparing three artifacts: CBS 6894, UET VI 10, and the current artifact. As Alster noted, the Yale tablet was an important part of his translation.
