Attestations of Isimud are available from between the
Early Dynastic and
Late Assyrian periods. However, no
temples dedicated to him are mentioned in known texts. In the first millennium BCE, Isimud received offerings in building rituals. He was also one of the deities belonging to the local pantheon of
Uruk in the
Seleucid period. It is not certain if he was already worshiped in this city in the
Neo-Babylonian period, though this possibility is accepted by Julia Krul. According to
Paul-Alain Beaulieu, the attestations are limited to two possible references in ritual texts, but the reading of the theonym is uncertain. He speculates that since no references to a separate sanctuary dedicated to him have been identified, he might have been worshiped in the
Eanna complex like many other minor deities. Later on, a cella dedicated to him existed in the Bīt Rēš, a newly built temple dedicated to
Anu and
Antu. It was likely located near the main gate, but as there is no agreement which of the entrances fulfilled this role, two separate rooms discovered during excavations have been identified as Isimud’s dwelling, 48 and 79b (the latter alternatively assumed to be the cella of
Kusu). He might have been regarded as one of the divine guards of the temple complex, alongside
Nuska,
Papsukkal and
Pisangunug. While absent from legal texts and
theophoric names, he is attested in ritual texts. He is mentioned for example in descriptions of the
akītu ceremony. In this context, he forms a trio with Nuska and Papsukkal. Either in the Neo-Babylonian period or later, Isimud was also worshiped in
Babylon, and appears in a ritual text in which priests follow him to various temples. He is mentioned in a text describing a procession taking place on the fourth day of the month Kislīmu, which involved a slave riding on the back of a bull.
Hurrian and Hittite reception Isimud was incorporated into the
Hurrian pantheon as well. According to Alfonso Archi, he was received by the Hurrians from Mesopotamia alongside
Ea and his wife
Damkina. He was also among the Hurrian deities who were introduced to
Hattusa.
Hittites similarly worshiped him alongside Ea. A single
theophoric name invoking him has been identified among the names of princes and officials of the Hittite Empire, in which only four other Hurrian deities,
Ḫebat,
Šarruma,
Šauška and
Teššub are otherwise attested. During the festival, he received offerings of meat and bread, as well as ritual
libations. ==Mythology==
