Ea's "faithful spouse" was the goddess Damkina, who was also called
Nin-ki, "lady of the earth". "May Ea make thee glad", chanted the
priests. "May Damkina, queen of the deep, illumine thee with her
countenance; may Merodach (Marduk), the mighty overseer of the Igigi
(heavenly spirits), exalt thy head." Merodach was their son: in time
he became the Bel, or "Lord", of the Babylonian pantheon.

Like the Indian Varuna, the sea god, Ea-Oannes had control over the
spirits and demons of the deep. The "ferryman" who kept watch over the
river of death was called Arad-Ea, "servant of Ea". There are also
references to sea maidens, the Babylonian mermaids, or Nereids. We
have a glimpse of sea giants, which resemble the Indian Danavas and
Daityas of ocean, in the chant:

Seven are they, seven are they,
In the ocean deep seven are they,
Battening in heaven seven are they,
Bred in the depths of ocean....
Of these seven the first is the south wind,
The second a dragon with mouth agape....[44]

name, signifying "the high one", is derived from "ana", "heaven"; he
was the city god of Erech (Uruk). It is possible that he was developed
as an atmospheric god with solar and lunar attributes. The seven
demons, who were his messengers, recall the stormy Maruts, the
