Provenance:

Notes: 

"The crescent standard occurs frequently on Old Babylonian seals that show cursory engraving. It is uncertain whether it was intended in 536 to identify the deity standing beside it as the moon god, Sin, especially since the symbol of the weather god, a lightning fork on a bull, appears behind the figure in question." Porada, CANES, p. 60
