This name refers both to a sister of Dumuzi known from some of the texts pertaining to his death, and to a primordial deity paired with Alala and listed in enumerations of ancestors of Anu.
[1] Belili appears in two distinct roles in Mesopotamian texts, as a sister of Dumuzi and as a primordial deity counted among the ancestors of Anu.

[20] Andrew R.

"[27] In the Desert by the Early Grass, a collection of laments dedicated to temporarily dying gods mourned by their respective mothers or sisters, mentions Belili alongside Amashilama, Ninazimua, Geshtinanna and three deities whose names are not preserved.
