While Jabru is described as an Elamite god, he is known exclusively from Mesopotamian texts, and attestations of him are infrequent. An Elamite town named Jabru did exist, but according to the Assyrian
Tākultu text its tutelary deity was a goddess named Jabrītu. It was located close to the border of Elam and
Babylonia, and appears in an inscription of
Amar-Sin mentioning it was destroyed alongside Huhnur, presumed to be the cult center of
Ruhurater. According to a
Šurpu commentary, Jabru was the Elamite equivalent of the
Mesopotamian god representing the sky,
Anu. However, according to the god list
An = Anum, a god bearing the name Yabnu (
dia-ab-na) was instead the "
Enlil of Elam".
Wilfred G. Lambert concludes that both of these theonyms are variant spellings of the same name. In an
Assyrian text known as the
Underworld Vision of an Assyrian Prince (VAT 10057), Jabru is mentioned as one of the three gods guarding the corpse of a king, the other two being
Humban and
Napirisha. Alexandre Lokotionov notes that this sequence of gods mirrors the reference to Jabru in Šurpu, and that its inclusion possibly indicates that to the Assyrians the underworld "could have simply been a repository for the exotic and the unusual." ==Speculative identification==
