Weather god and sun disk

"In Old Babylonian representations the weather god, Adad, is usually shown standing on a bull and holding a lightning fork; often he also holds the bull's rein. This portrayal is probably related to the somewhat similar representation in the glyptic of the Assyrian merchant colonies in Anatolia... 509, 510, 512, 514 may be of other than Babylonian origin... Seal 512 has in its inscription a name conforming with names used in Nuzi in northern Mesopotamia... The inscription of this seal not only contains a name that conforms with names found in Nuzi, but also carries over from one line to the next--a feature observed in inscriptions on seal impressions from Nuzi but not in those of Old Babylonian cylinders."
