Ningal

Ningal (Sumerian: NIN=lady, GAL=great: Great Lady), one of Enki's daughters, became the wife of the Sumerian Moon god, Sin (also Nanna-Sin or Nanna-Suen). Ningal and Sin produced three very famous children, Shamash, the Sun god, Ereshkigal, the Queen of the Netherworld, and Innin, who became Inanna (later, Ishtar), the Queen of Heaven.

Like Sin, her husband, Ningal had temples at Ur and Harran. Ningal's crytographic number was 25.
