The use of Šarru as a divine name is always puzzling.  Many of the gods appear in Assyrian names as Šar-ilâni, "king of the gods."  Šar-ilâni-ilai is an Assyrian name.  But when we meet with Šarru-dilini, Šarru-habi, are we to understand that these names imply that to a certain extent the reigning king of Assyria was paid divine honours?  Or is šarru another name for Šamaš, as Dr. Bezold takes it to be in the Fifth volume of the Catalogue?  I believe the former supposition is the true one.  This is confirmed by the fact that not only Šarru, but also Ahu and Abu replace the divine names in all sorts of compounds.  Unless we are to suppose divine honours paid to brotherhood and fatherhood.  The name Apil-šarri-ilai is very suggestive in this connection.  No one surely supposes there was a god called Apil-šarri, or that the "king's son" was identified with Malik.
