While you are learning all about the Anunnaki, you are going to stumble across a lot of different proper names for various gods and goddesses, one of which is “Anu,” or “An.” Many of these names are similar and can easily be mixed up if you do not take some time to learn the Sumerian family tree.

First things first—in case you are still quite new to researching the Anunnaki, I want to make sure you understand the basics before proceeding further.
Depending on whom you are speaking with, the “Anunnaki” may refer to either:
• A set of ancient Mesopotamian deities
• Space aliens who interacted with ancient cultures here on Earth
The mainstream view of course only recognizes the Anunnaki as fictitious Mesopotamian gods.
Those who support the alien theory equate the two, but disagree with the “fictitious” assertion.
Their belief is essentially that the Anunnaki are real, literal beings, and that what the ancient peoples of Mesopotamia referred to as “gods,” we would presently call “aliens.”
Clearly, that is our belief here at Annunaki.org.
Now, one of the most important Sumerian gods is the Sky Father, An, known interchangeably as “Anu.”
Anu, God of the Sky
There are a number of Sumerian tablets and texts which discuss Anu, but not all of them agree on every aspect of his existence (as is typical with any system of mythology). The earliest texts available for example do not explain where Anu came from at all—as if he was simply there. Later texts however state that he is the son of two primordial deities known as Anšar and Kišar.
As the Great Father of the Sky, Anu holds the highest position in the Sumerian pantheon—at least in name. In terms of power, he eventually shares his authority with Enlil and later Marduk (who also in some ways end up surpassing him).
In the Sumerian creation myth, heaven and earth were originally joined together. Anu had two consorts, Antu, Great Mother of the Sky, and Ki, the Earth Mother. He had children by both of them. With Ki, he had Enlil, Lord of the Air and Earth, and Nin-khursag, Lady of the Mountain. With Antu, he sired Enki, Lord of the Earth and Waters. These are all very prominent figures in Anunnaki mythology.
Note that there is some confusion over Ki’s identity. Ki is rarely mentioned in Sumerian texts, and it is unclear who she is and whether she was worshipped as a goddess.
Enlil cleaved apart the earth and heaven after he was born, separating the two forever. Ki and Enlil assumed direct authority over the earth. Anu held court in heaven.
I highly recommend that you look at a family tree diagram for the Sumerian pantheon at this point. You will see that there are a number of primordial gods who came before Anu, and also that he has many descendents through his children. This helps to give you a broader idea of the context of his reign. You can also follow the branches of the tree through to see how he is related to more distant descendents such as Ishtar.
Anu As a Source of Authority
As the original supreme Babylonian deity, Anu was seen by worshippers as the ultimate source of authority. He was responsible for conferring power on other deities as well as on mortal kings, which is exemplified through a number of stories in Sumerian mythology.
As one example, in the poem Inana and Ebih, Inana/Ishtar reports that, “An has made me terrifying throughout heaven.”
Whenever other deities were given powers of leadership, they would even go so far as to say that they had been given anûtu. This word quite literally translates as “Anu-power.”
In Enūma eliš, the Babylonian creation story, Marduk (son of Enki and Damkina) rises to the key position of power among the Anunnaki. When he does, his might is legitimized through a declaration among the gods: “Your word is Anu!” This phrase can be found in lines 4-6 of Tablet IV.
This is really quite extraordinary when you think about it. Anu’s power was so deeply respected that in many ways, Anu was power. It is very easy to read “Your word is Anu!” as “Your word is might!” or something similar along those lines. That was essentially what it meant.
In other words, even though Marduk had risen to a position of authority which eventually surpassed that of Anu, without Anu, his own power would have had no meaning. It was defined through Anu. In this sense, the idea of Anu continued to hold sway, even though the gods were now taking their marching orders from Marduk.
The Meaning of the Word “Anunnaki”
And that brings me around to a discussion about the meaning of the word “Anunnaki.” This is a source of some confusion, especially among those who believe that the Anunnaki are alien visitors.
The primary proponent of the Anunnaki theory was a Russian-born American writer named Zecharia Sitchin. Sitchin had some fascinating ideas, but to the mainstream detractors he was a notoriously horrendous translator.
This has caused many scholars to look down on his work and not take him seriously, despite his massive influence on pop culture and modern alien lore.
In his book The Twelfth Planet, Sitchin translates “Anunnaki” as “those who from the heavens came.”
Modern linguists say this isn’t quite right though.
Two closer translations would be “princely offspring,” or “offspring of Anu.” These are the correct translations which the majority of serious scholars agree upon.
While Sitchin’s translation may be off, in my opinion it is easy to see where he was coming from and why he thought that it was essentially correct. I think an argument cannot be made that his translation wasn’t totally illegitimate- it is possible to understand his sentiment and acknowledge that it was not 100% correct.
Sitchin probably did realize that “Anunnaki” meant “offspring of Anu.” He then took that and made it, “Those who from Anu came.” He then took that a step further, incorporating his understanding of Anu as Great Father of the Sky. Anu, as you know, reigned over heaven. So Sitchin simply took a literal approach, equating Anu to the Sky. From there, he could easily turn “Those who from Anu came” into “Those who from the Sky came.”
So is Sitchin’s translation wrong? Technically, maybe it is—but it was also an interpretive translation.
Depending on how you want to interpret Sumerian mythology, you could argue that on some level it makes a degree of sense. Anu was of the Sky, and the Anunnaki came from Anu—and therefore from the Sky. And if you believe that Anunnaki are aliens, you are already in a highly interpretive territory.
Key Points In Understanding Anu / Anu
Because Sumerian mythology can be complicated, especially when you are trying to figure out how it all fits together with the alien theory, I want to wrap this up by summarizing the key points that I have covered. That way you know the main takeaways.
• Anu, also known simply as “An,” is the Sumerian sky god.
• Anu is the son of Anšar and Kišar, and the father of Enlil, Enki and Nin-khursag.
• Anu is one of the most powerful Sumerian deities. His authority is so central to Babylonian mythology that the other gods evoke his name when power is conferred upon them. Even when Marduk surpassed Anu, the other gods said, “Your word is Anu!”
• The word “Anunnaki” is derived directly from Anu’s name, and translates properly to “offspring of Anu.”
• While Zecharia Sitchin technically mistranslates “Anunnaki” when he says it means, “Those who from the Sky came,” it is easy to see how this meaning connects directly to the true translation. Whether you see this as further evidence that the Anunnaki are aliens or not is totally up to your interpretation.
So now you are more familiar with one of the key players in Sumerian mythology.
Be sure to also read up on Enki, Enlil and the other gods so that you have a complete understanding of the Anunnaki!
