The archives of the temple of Ninurta, the é-šu-me-ša4, in Nippur, extended over more than seventy-five years, from year 1 of Lipit-Enlil of Isin (1810) to year 28 of Rim-Sin I (1730) and were inadvertently preserved when they were used as infill for the temple of Inanna in the Parthian period. The 420 fragments show a thriving temple economy absorbing much of the available wealth.[32] The year-names following his accession year all somewhat monotonously commemorate generous gifts to the temple of Enlil.
