Bel (/ˈbeɪl/; from Akkadian bēlu), signifying "lord" or "master", is a title rather than a genuine name, applied to various gods in the Mesopotamian religion of Akkad, Assyria and Babylonia. The feminine form is Belit 'Lady, Mistress'. Bel is represented in Greek as Belos and in Latin as Belus. Linguistically Bel is an East Semitic form cognate with Northwest Semitic Baal with the same meaning.
Early translators of Akkadian believed that the ideogram for the god called in Sumerian Enlil was to be read as Bel in Akkadian. This is now known to be incorrect; but one finds Bel used in referring to Enlil in older translations and discussions.
Bel became especially used of the Babylonian god Marduk and when found in Assyrian and neo-Babylonian personal names or mentioned in inscriptions in a Mesopotamian context it can usually be taken as referring to Marduk and no other god. Similarly Belit without some disambiguation mostly refers to Bel Marduk's spouse Sarpanit. However Marduk's mother, the Sumerian goddess called Ninhursag, Damkina, Ninmah and other names in Sumerian, was often known as Belit-ili 'Lady of the Gods' in Akkadian.
