The image on the right gives you some idea of the cosmos as understood by the peoples living in this part of the continent when the Spanish arrived, and for many generations before. The yellow-green grassy layer with the central pine is the level people live on, with a dome above and water below, and distinctive edge-cliffs. Spirits are above and below and with the people. Note that the three red circle figures are slightly different for the people world and the realms above and below.
The image on the left is of a large shell with a supernatural creature carved on it that looks like a segmented snake. Snakes are more associated with the water world below. Archaeologists call them gorgets; the dictionary definition of that is a throat cover—armor or clothing—but I suspect these were worn or placed a bit lower, although this part of the past isn’t my specialty.
That’s all the context I will give you now, other than that my friend Adam used this artwork in his interesting and informative presentation this evening. I’m still processing it, and that’s a good thing.
