CBS 13908 (clay tablet) is a clay cuneiform tablet containing lines 52-74 (obverse) and 76-97 (reverse) of the Sumerian afterlife myth titled "Inanna's Descent to the Netherworld." This artifact is housed at the Penn Museum in Pennsylvania and was first documented by a Sumerian scholar named Edward Chiera. It belongs to the Old Babylonian collection and was later re-published by several new scholars like Samuel N. Kramer and William R. Sladek.
The tablet is highly fragmented and the obverse side of it is classified as destroyed due to the wear and tear of time.
Discovery and publication
CBS 13908 was discovered during the Nippur excavations in modern-day Iraq between 1899-1900. Several excavations took place jointly between the University of Pennsylvania and the Ottoman Museum in Turkey. The artifacts sat in boxes at the Pennsylvania Museum until Edward Chiera (1885-1933), a Sumerian scholar who did lots of work on artifacts related to "Inanna's Descent," started publishing pictures of the fragments.
Before passing away in 1933, Chiera was working on publishing his artifact discoveries at the University of Chicago's Oriental Institute. His work was posthumously published in 1934 in Sumerian Epics and Myths In this publication were the first images of CBS 13908 (as plate number 48). Because Chiera only published sketches of the artifacts, it would take several years before other scholars would translate what they meant.
Importance for "Inanna's Descent"
In 1942, Samuel Kramer published a translation (and collation) of "Inanna's Descent," where the line numbers were carefully mapped out for this artifact. This publication is referred to as PAPS 85 in citations, short for the Proceedings of the American Philosophical Society; however, the journal seems to have gone defunct in 2015.
Kramer also published a revised translation of these artifacts in 1951 (in the Journal of Cuneiform Studies) as part of his many revisions to the myth's decipherment. This 1951 version of "Inanna's Descent" would remain as the main version of the myth until William R. Sladek published a revised translation in 1974.
