JS30-93 ~ The Giants Canibalized the young (The Hewixi) ~

This is the way the Hewixi were in the First Times, when this world was discovered, how they eat each other, how they swallow each other.

They hunted in what they would call traditional way and hunted a young girl, or young life. They did not hunt down an old person for the sacrifice, because their gods did not accept it in that way.

They kept the flesh and the next day, they would distribute it among themselves.

So the Hewixi are the ones, who way in the past, battled with the ancestors of the Huichol and they controlled the land, where the Huichol established themselves and are established to this day.

So we have two Hewixi, both being victims of human sacrifice. The arrows were anointed with the blood of the victims.

And then we have parts of thier body, because the Hewixi were really not very human in a real sense, they were also giants, they were strange beings, who transformed themselves into wild animals (we see parts of their cloas). We also see parts of the body, the flesh, that has been kept, you see a head, spine, feet, ribs and two hearts.
