Ninlil is the wife of Enlil, considered to rule over Saturn in the feminine sense, we see her motive power driving the rotation of the cosmos via the swastika.

the swastika, the sonnenrad or black sun depicts the rotation of the Heavens around the axis mundi, the former in seasons marked by Ursa Major, the latter twelve sig runes denoting the astrological signs of the zodiac. The swastika and Polaris mark the central sun, the sonnenrad the base, underworld inner aspect, chthonic in nature.

Erra the Fox is the God Sig-sig, Lord of Dreams, along with Isum and Hendursanga, they are the nightwatchmen, the light in darkness of the underworld, heralds of the silent night. He purifies and drives out evil, just ask.

>Utu, the great lord of Arali, After he turns the dark place into light he will judge your case. Let the child of the sun-god Utu, *light up for him the netherworld, the place of darkness!

>What Ninlil did, having given birth to Išum, was to set him alight. The two lines are to be translated, “Ninlil bore Išum for Šamaš, then set (him alight) and left him in the street.”
