Thus of the twelve seals for which any sort of dating can be postulated, seven may be Sargonid, one pre-Sargonid, and four of the Larsa or later periods. On current dating, the maximum period required to cover these possibilities would be 2500–1500 B.C., with a strong focus on *c.* 2350 B.C. But the ends of the bracket are very insecurely dated by the seals, and collateral evidence must now be considered.
