Shamash vs Sin

The sun god and divine judge. Shamash sees all that occurs under the sun and is the god of justice, truth, and moral order.

Shamash is the son of the moon god Nanna/Sin, emerging from the underworld each dawn through the eastern mountains. Each night he descends through the western gates to travel through the underworld, bringing light even to the realm of the dead, before rising again at dawn.

Shamash traverses the sky each day, seeing everything that occurs beneath his rays. This all-seeing nature makes him the natural god of justice and truth. Nothing can be hidden from his sight, no lie escapes his notice, no injustice occurs beyond his witness. He is the great equalizer who treats beggar and king alike.

The moon god and lord of the night sky. Sin is the father of the sun god Shamash and the goddess Inanna, and the keeper of time through the lunar calendar.

Sin was born to Enlil and Ninlil in the underworld under unusual circumstances. After Enlil was banished to the underworld for ravishing Ninlil, she followed him and gave birth to Nanna/Sin there. Through clever deception, Sin was allowed to ascend to the sky, where he became the moon.

Sin is the great moon god of Mesopotamia, father of the sun and stars. In Mesopotamian astral hierarchy, the moon held precedence over the sun, as the moon's phases provided the basis for the calendar and the measurement of time. Sin's waxing and waning represented the cosmic rhythm that governed agriculture, religion, and commerce.
