Tarot Retablo

I found this Retablo in the Philadelphia Museum of Art. It is from Peru and seems to depict some sort of healing ceremony using snakes. There is a woman laid out on a platform with someone waving snakes over her. Snakes are everywhere in the room. They hang from the walls and ceiling and other people in the room are holding snakes as well. The detail is really amazing.What really caught my eye in this piece were the inside doors, which depict tarot cards - Death and the Devil.
