Nanna (moon god)

Nanna, also called Sin, is an ancient Mesopotamian lunar deity associated with the moon. Revered as the god who governs night, time, and lunar cycles, Nanna played a vital role in calendar systems and religious rituals. Often depicted as a wise and stabilizing figure, Nanna's influence helped ancient societies track months and seasons. Worshiped primarily in Sumer and later in other Mesopotamian cultures, the god embodies the moon's steady, cyclical nature, symbolizing continuity and order in the cosmos.
