... That Shamas, or Shemesh, "the sun," was worshipped separately from Baal has been already mentioned.  In Assyria and Babylonia he was one of the foremost deities; and his cult among the Phoenicians is witnessed by such a name as Abed-Shemesh (q.v.), which is found in two of the native inscriptions... (The Religions of the Ancient World, Rawlinson, 1885).

SHEMESH.  Or SHAMASH.  In Babylonian mythology the son of Ningal, and the god of the sun.  He was called the "Judge of Heaven and Earth," "Director of All," and "Lord of the Cities of Larsa and Sippara."  His consort and sister was the goddess Ishtar, the daughter of Sin, who must not be confounded with Ishtar, the daughter of Anu.  His analogue was the Shemesh or Shems of the Syrian religions.
