Three names that appear more often as a sacred group of three are …
Ninki - (later became Ishtar) the mother
Enki - (later became Namakh) the father
Marduk the son
This Trinity representation evolved a little further. In the ancient ruins in Syria centuries later after the belief had been passed down many generations, long before The Christ, some names were altered for unknown reasons. Perhaps in the same way the name Yeshua, a Hebrew Aramaic name was altered to become Jesus, a more acceptable Roman name after someone of the authority like Emperor Constantine had altered it. The same three Sun gods from Sumer now as follows… from left to right… Marduk the son on a lion, Enki… now as Namakh the father still retaining the bull of Taurus, and
Ninki… now as Ishtar on another lion.
