Worship of Wer is chiefly attested from the middle
Euphrates area, northern
Babylonia (though only before the
Middle Babylonian period), the
Diyala area, and
Assyria. While confirmed attestations go back to the time of the
Akkadian Empire, only from the
Old Babylonian period onward the god is known from sources other than
theophoric names. Wer appears in nine types of masculine theophoric names from Old Babylonian Mari, with eight using the spelling Mer and one - Wer. Furthermore, the names of the local deities
Itūr-Mēr and Tar’am-Mēr are both agreed to be theophoric names invoking him. Other sites where names invoking him are attested include
Sippar, various locations in Assyria (in the Old Assyrian period) and the Diyala area,
Puzrish-Dagan (Puzur-Wer from the Ur III period) and
Larsa (Ubār-Wēr from the Old Babylonian period). A possible seventh century BCE attestation of a theophoric name invoking him as Ber,
dnbr, usually interpreted as Dannu-Ber, "Ber is strong," is known from an
Aramaic papyrus found in
Saqqara in
Egypt, However, the restoration is not certain, and according to Daniel Schwemer caution should be maintained. References to veneration of Wer other than theophoric names are absent from the corpus of Mari texts, though a place named Bāb-Mēr (KÁ-
me-erki) is attested in a single source from the
šakkanakku period. Furthermore, later texts from the
kingdom of Ḫana attest the existence of a house of worship dedicated to him (akīt
dme-er) in nearby
Terqa. He was also apparently worshiped in Nerebtum,
Shaduppum and Kakkulatum. A school text from
Kanesh, an Assyrian trading colony in
Anatolia, mentions him alongside
Ashur. In the Neo-Assyrian period, he was worshiped in Assur in the temple of Ištar-Aššurītu ("the Assyrian
Ishtar"), and in
Nineveh in the temple of Ashur. He is also mentioned on the Antakya stele of
Adad-nirari III alongside Ashur,
Adad,
Sin of
Harran and other deities. Additionally, in the same period Iluwēr, most likely the same deity, was worshiped by
Arameans in
Tell Afis in Syria, as attested on the
Stele of Zakkur. ==Mythology==
