The narrative relates that he mounts the monsters, “slain heroes,” he has defeated as trophies on his [gišgigir z]a-gìn-na, “shining chariot.” Echoing the number of Tiāmat’s eleven monstrous offspring, (from the Enûma Eliš, whom Marduk had vanquished), Ninurta’s conquests included: He then journeys with his attendants, Udanna, the all-seeing god, Lugalanbadra, the bearded lord, and Lugalkudub, with full battle regalia in a terrifying procession to Nippur.
In the Ekur, he displays his trophies and booty to the general astonishment of the gods—including his brother, the moon god Sin, father Enlil, and mother Ninlil.
Ninurta then extols his virtues in a long hymn of self-praise in an effort to solicit the establishment of his own cult.
On his departure from the Ekur, he is petitioned by the god Ninkarnunna to extend his blessings to the king, perhaps the underlying purpose of the whole poem.
It may have been recited during some kind of cultic activity, such as the annual transport of the Ninurta idol between the temples, Ešumeša and Ekur.
