I suspect the images on the tiwanaku statues are a representation of ‘Ometecuhtli’.
“(Aztec; Ome, “duality” and Tecuhtli, “Lord”) The Lord of Duality. This is seen as the Androgynous nature of the Spirit. He is represented as being joined with his spouse Omecihuatl (see entry by that name). Ometecuhtli-Omecihuatl is the Aztec Osiris-Isis, Joseph-Mary, Shiva-Shakti, or Samantabahdra-Samantabahdri. This aspect of the Spirit is seen Kabbalistically within Daath, where divine creativity resides. The conjunction of Ometecuhtli-Omecihuatl is called Ometeotl, the one androgynous spirit.
The dwelling place of Ometeotl is the Omeyocan. The children of Ometecuhtli-Omecihuatl are the four aspects of the Cosmic Christ: Tezcatlipoca, Huitzilopochtli, Quetzalcoatl, and Xipetotec. See Omeyocan, Tezcatlipoca.
These might well be the 4 directions.
Wordly conceptual and visual parallels in Greek and Egyptian cultures
Further interesting Parallels are there on the female aspect and its representation, the snakes, with Egypt, representations of Wadjet, as dual snake headed women which in turn is the later female aspect Medusa, the Minoan snake godess and Aztec Coatlicue.
We see the dual headed snake figure also in Egypt and behold also holding the snakes. A representation of Wadjet. The female aspect of Duality.
Quite similar to Viracocha, yet the Egypt version is only the female aspect, while Viracocha is male and female combined.
And the Minoan snake godess, again only female aspect of nature.
Or isis on the Qetesh stele.
The lion below her as Leo is close to virgo, it links her to the Indian Durga, Brittania and other archetypes. (Shiva is male aspect) In modern times this translated to the red and blue Colour in occultism. Shiva and Durga are also seen as a combined God. Duality in 1, the universe. (Virgo/Leo and Otion/Taurus, sungod and moon, male and female etc)
Here below another Egyptian representation of Wadjet, the female aspect , compare it to the tiwanaku figure in the statues left hand. (right for you.) it’s the female aspect of the duality.
The dual snakes is the female aspect of nature.
It is important to understand that sometimes the female aspect is depicted as stand alone and sometimes male and female are in 1 image.
Examples of combined imagery, the two figures in tiwanaku statues hands, viracocha(male/sun) holding snakes (female/moon), young horus (male/sun) holding snakes (female/moon) and the sundisk with the two snakes.
Here below we see from the mochicha culture that predated chavin the disk of sun with the two snakes and priest on top. Again a duality, identical to the Egyptian sundisk in execution and concept.
Stand alone images of the female aspect are Wadjet in human form with two heads, Medusa, Coatlicue.
Now if we look back at the Mochicha culture we see this:
Or, at the Aztec calender stone…
The similarities are obvious. It’s the female aspect of nature.
Hindu godess Kali
So how can these cultures, Greek, mochicha, Aztec, Egyptian, Indian, that have nothing to do with each other come up with identical concepts?
The easiest way out is to blame Jung archetypes.
Yet the visual execution is also very similar. The fanged teeth, the tongue, the dual snake heads, the snakes for female aspect. Shiva wearing the cobra like Egyptian pharaohs the uraeus. It is to much to ignore as ‘mere coincidence.
As mentioned above, the sundisk with two snakes, is not just a random image. It’s not only a sundisk.
It is a representation of the combined dualistic nature of the universe in 1 image.
It is the same concept as Viracocha (sungod) holding two snakes or Horus on top of Wadjet in hatshepsut temple.
Wadjets head just has disapeared as can be seen from steles on same temple. The snake body next to the stairs is still to be seen.
We have seen snakes on balustrades before in other ‘unrelated’ cultures.
To conclude, identical representations of duality span global cultures.
They not only share concept but also execution and visual representations that can not be ignored any longer. The fact that the Tiwanaku culture has visual similarities and cultural duality concepts executed also in Egypt, like mentioned above is worthy of considering the possibilities of a shared ancestry or cultural global contact and exchange by a previous civilization.
