Names for specific conceptions of god: YahWeh?, JesusChrist?, the HolyTrinity, TheGodhead?, AllAh?, KrishNa?, BuddHa; then there are the many names for the many different gods of polytheistic religions, e.g., ZeUs?, JupiTer?, OdIn?, and SiVa. In old persia the name of the sun god was shamash (or sha.mash). According to the old sources his sister "Ishtar" (AKA "Ianna") represented the goddess of the moon. In some narrations the both of them were mixed up, so Ishtar was the goddess of the sun and shamash was the god of the moon. Shamash -being the sun god- was the first to be pictured with a sort of corona. In a later time the christian religion adapted this kind of image when the holy saints got their gloriole.
