Angels-NERGAL

Nergal was the Mesopotamian Mars, a god associated with war and
death. He was apparently adopted as a guardian spirit by the
Chaldeans, one of the groups of people who ruled the Mesopotamian
area in later centuries. His marriage to Ereshkigal, queen of the underworld,
caused him to be identified as king of the underworld in later
syncretistic religions, such as certain strands of Gnosticism. In certain
reference books (e.g., Gustav Davidson’s Dictionary of Angels), he is
mistakenly identified as one of the great winged centaurs of ancient
Mesopotamia, which explains his association with angels in some
writers’ minds. Also, in at least a few occult books, Nergal is identified
as chief of the “secret police” in the infernal regions, thus causing him
to be associated with fallen angels.
