"Seal 253 must have been made when the influence of the Akkad period was still predominant, because its enthroned god faces right. In Akkad designs there seems to be no convention in this respect; on seals of the following period, however, it is exceptional for an enthroned god to face right. The Sumerian inscription, however, shows that the seal was made after the fall of the Akkad dynasty, when Sumerian became once more the official language of the country. A Post-Akkad dating is furthermore indicated in view of the fact that the worshiper is beardless, as in later representations, whereas on seals of the Akkad period, worshipers are bearded."
