Asar was already attested in the Third Millennium as part of incantations, albeit playing a minor role. Asalluhi often appears in incantations in relation to his father
Enki. This type of incantation follows the formula where two deities are engaged in a conversation, discussing how to treat the patient. In his studies on incantations, Falkenstein has dubbed it the
Marduk-Ea type invocations. However, the name is not very representative of the whole, and Cunningham has shown that the formula was attested earlier in the Fāra and
Ebla texts, with
Enlil taking the role of Ea and
Ningirima taking the role of Marduk. Earlier incantations had Asalluhi send a messenger to Enki to seek support, but starting in the Ur III period Asalluhi started to occasionally directly seek out Enki in his temple to ask for support, possibly emphasizing the mediating role of temples instead of messengers. The general structure of the Asalluhi-Enki dialogues starts with Asalluhi noticing a problem and reporting to his father Enki. Enki assures Asalluhi that he knows everything that he knows, and then proceeds to instruct Asalluhi on the procedures. Geller argued that during the Old Babylonian period the incantation priest would assume the role of Asalluhi, who would be acting as the messenger for Enki. Johandi notes that such a translation would not make sense for some of the texts, and there is nothing like the first millennium texts where the priests directly claim to be in the image of Asalluhi/Marduk, although the option still remains possible. Asalluhi also appears in what is commonly termed the legitimation-type formula as per Falkenstein. The priests will legitimize themselves by establishing them as the representative of the gods. As most of the incantations of this type are directed against demons, Enki and his circle feature prominently among them. The priest would claim that the incantation is the incantation of gods such as Asalluhi, while in other texts they would claim that the gods themselves cast the incantation. Asalluhi is claimed to be the one to recite the "incantation of Eridu" in the Old Babylonian period, whereas in earlier periods the role was assumed by the human priest. Asalluhi also features in consecration incantations, which prepares objects and materials for rituals. In particular, he seems to appear in preparing objects for purification. Although in hymns Asalluhi's role as an exorcist is not stated, and outside of incantations his connections with magic are doubtful, his role as a divine exorcist was already well established by the Old Babylonian period. It would still seem that in the Asalluhi-Enki formula, Asalluhi functioned as the executor of Enki's orders, and Asalluhi cannot be called an expert, lacking initiative and needing Enki's encouragement. In other texts, such as a myth, and incantation texts of other formulas like the legitimation-type, though, Asalluhi is described as an exorcist or as the exorcist of the gods. In the Sumerian
Temple Hymns, Asalluhi is described with more aggressive characteristics, listing epithets like "the strong prince", "the hero", and was even described as a leopard and a storm. The other name given to Asalluhi in the hymn, Asaralimnuna can either mean "Asar, the princely bison" or "Asar, the bison of the prince." Johandi notes that this imagery is reminiscent of the young warrior gods archetype, for example
Ninurta. Asalluhi seemed to have a relationship with the deified
Shulgi, who was honored in Asalluhi's temple in Kuara. Other texts relate Asar/Asalluhi to deities associated with the underworld and other deified kings, so it is possible that Asalluhi may have had a connection with the underworld. Jacobsen had argued that Asalluhi was originally a storm god based on the reading of lú-ḫi as lú-ḫe, which would translate the name Asalluhi as "man-drenching Asal," and that Ishkur was also attested with the lú-ḫe epithet. Johandi suggests that it is possible, however there is no other evidence pointing to Asar/Asalluhi originally functioning as a storm god, and points out that a deity being associated with storm imagery does not corroborate to a deity being a storm god with Ninurta being the prime example. Asalluhi was also said to have granted wisdom to Mesopotamian kings in a couple texts, taking over the role usually reserved for Enki. In Asalluhi A, Asalluhi was described with several traits reminiscent of that of Enki. The sharing of traits with Enki is likely due to the father-son relationship. In contrast to his usual portrayal as a deity benevolent to humans, some texts, namely Sin-Iddinam's prayer to Ninisina and another Old Babylonian letter relate Asalluhi to plagues. Oshima believes that Marduk was the god related to disease and sickness and Sin-iddinam's prayer is suggestive of Marduk's possible original role before the identification with Asalluhi, but Johandi disagrees and suggests that Asalluhi may have had a similar role prior to the identification with Marduk as the letter was dated quite early (reign of
Sumu-abum), although evidence for Asalluhi's role in human sickness is scarce. Asalluhi's implied ability to cancel incantations could also point to a less benevolent side to the god. == Associations with other deities ==
