> A later phase, as represented by this tablet, reflects changes in the techniques of writing that altered the shapes of signs. Symbols stood for nouns, primarily names of commodities, as well as a few basic adjectives, but no grammatical elements.

From Weavers, Scribes, and Kings:

> The reason that the artist immortalized Ushumgal and Shara-igizi-Abzu is that they were involved in a transaction so important that a record of it was carved onto a stone boulder, complete with pictures of the main parties. The roughly drawn cuneiform signs that litter the sides of the boulder, and even extend over the figures themselves, record that this transaction pertained to animals, land, and houses, in large quantities: 450 iku of fields are mentioned (about 158 hectares or 392 acres), along with three houses and some bulls, donkeys, and sheep. Unfortunately, the inscription suffers from a dire shortage of verbs, which would have been useful in determining what exactly was going on.
