Who created literary texts in ancient Mesopotamia, and did the Mesopotamians have a concept of “literature” (→ 1)? A core witness is the song Innana B / nin me šara (NMS → 2). New translations and an inductive analysis of references to text, addressee, and speaker reveals NMS to be created by a priestess for a war ritual (→ 3). Instead of staking a claim to authorship, however, the song stresses a claim for priesthood (→ 4). New evidence shows why: the creators of ritual songs are gods, and En-ḫedu-ana is only allowed to create such a song when she herself acts as a priestess embodying a deity (→ 5 and 6). The last section will offer proof that NMS belongs to the category of literature, from both ancient and modern perspectives, and explain why it is also to be regarded as both a mythic and ritual text (→ 7).The analysis demonstrates the birth of literature through the goddess Nin-gal, embodied in En-ḫedu-ana.
