Here is some info, as read from the video description provided by the poster:
Here are some videos I came across one day. They were taken in 1986 at an elementary school. I found it very weird to watch it 23 years later and see how much the world had changed. I'll bet the man is still alive. He can definitely understand it now better than in 1986.
*According to my knowledge (Lybertha's) they were recorded in 1976, but I won't claim to be right.*
edit: I'm sure this is just a convention.
The Hopi maintain a complex religious and mythological tradition stretching back over centuries. However, it is difficult to definitively state what all Hopis as a group believe. Like the oral traditions of many other societies, Hopi mythology is not always told consistently and each Hopi mesa, or even each village, may have its own version of a particular story. But, "in essence the variants of the Hopi myth bear marked similarity to one another."
It appears to be a 5 part video, I've watched all of it and I found it interesting, and I hope you do to!
