The Ni 4200 (clay tablet) is a cuneiform tablet that contains lines 211-233 (obverse) of the Inanna's Descent to the Netherworld afterlife myth in Sumerian cuneiform. This tablet joins (is part of) Ni 4187, which contains lines 234-253 (reverse) of the same myth. The Ni 4200 artifact was first published by Samuel N. Kramer in a 1939 publication of Revue d'Assyriologie et d'Archéologie Orientale (volume 36), a prominent journal. This article is commonly referenced as RA 36. Kramer published a translation, transliteration, collation, and commentary of the artifact.
The large tablet is preserved well on the obverse side but heavily damaged on the reverse side.
Most of the Nippur tablets related to "Inanna's Descent" were discovered in modern-day Iraq during expeditions by the British Museum in the 1890s. This artifact first appeared in a 1939 journal article by Samuel N. Kramer. Kramer also published another article in 1942 that included a recopy, as well as an improved translation. Subsequent publications by Kramer also utilized this artifact.
