Shamash is the sun god. He is also the god of truth and justice because he can see everything. Shamash holds a knife with a jagged edge so that he can cut his way through the mountains at dawn.
Shamash's symbol is a disc, sometimes with sun-rays, or a winged disc.
He was thought to travel in a boat, but from about 1000 B.C. his symbol became a horse, and later, a chariot.
