The image above depicts a typical cylinder seal of the Ur III period (ca. 2100-2000 BC). Its legend reads “Abbakalla, son of Ur-mes;” the inscription, however, was evidently cut into an imperfectly erased earlier legend, itself probably the more standardized formula “So-and-so, scribe (Sum. dub-sar), son of so-and-so.” The traces of ‛dumu ...’ are clearly visible in a third box below the end of our legend.
