Only the ends of lines of a large part of the ninth song are preserved in Rev. III. The tenth song probably occupied most of the space in Rev. IV. Speculation concerning the number of songs in the entire liturgy is limited to the number of about 11-13. The liturgy was, therefore, extremely long, attaining to a content of about 500 lines. We know from the single tablet variant of the sixth song that another edition of this series existed in which small tablets carried each a single kišub. A similar condition of editorial redaction is revealed by Zimmern, KL. 200, a small tablet which contains the twelfth song of a liturgy to the deified king of Isin, Išme-Dagan.
The historical event referred to in this liturgy is undoubtedly the destruction of Ur in the time of Ibi-Sin, last of the kings of the Ur dynasty. This calamity left many traces in the temple songs of Sumer, and the Sumerian prayer books of Nippur contain other lamentations on the fall of Ur, written perhaps during the Isin period. The writer has already published a single column tablet which rehearses the same catastrophe, mentioning Ibi-Sin himself and naming the Elamites as his captors.[247]
