In Irish mythology, it is said that a race of kings descended from the heavens to the ancient, pre-Celtic culture of Ireland. These tall, bright, shining creatures were elegant and beautiful and brought with them the secret knowledge of the gods.

They are often referred to simply as the Tuatha, Tua or the Tuatha Dé, which was also used in early Irish Christian texts as a name for the Israelite diaspora, which, in and of itself, is an interesting historical reference, as Danu has also been rendered Anu. The reference – if not already obvious – creates an interesting link between Israel and ancient Mesopotamian mythologies.

The people of the Israelite tribe of Dan intermingled with the Canaanite Tuatha De Danann, also known as the Dragon Lords of Anu, said to be the offspring of the ancient Sumerian Anunnaki. This is also one of the interpretations of the Sons of God intermingling with the “daughters of men,” referenced in the Genesis chapter six story of the Nephilim. One of the interpretations of the story is that the children of Israel, as represented by the tribe of Dan, broke the law of God and intermarried with the Canaanites in the region of Mount Hermon, where the Elohim (the Watchers of the Book of Enoch) were said to have descended. Hence, the basis of the story for the “Sons of God” intermingling with the “Daughters of Men.” This integrated tribe of Dan and Danaan/Danu/Anu migrated to the north and west, settling along the way in the European and Scandinavian regions as a conquering nomadic people, replacing those they conquered with their own traditions blended with the Canaanite Anunnaki Serpent culture.
