Edward S. Curtis. The Dance of the Gods. 1906.
Hmmmmmm….this picture merits more inquiry!
I found this is the Wikipedia, but it’s impossible to tell what the people look like (to learn more about the Tamil people, who represent ; hyperlink will get you to the Tamil article):
"Devarattam (“dance of the gods”) is the dance of the Kambalathu Nayakar community of Tamil Nadu, who believe that they are the direct descendants of the ‘devas’ or gods. The dance involves fast and fluent movements to the rhythmic sound of Deva Thunthubi, a drum-shaped percussion instrument.
Today, the dance is performed during festivals, marriages and other social occasions. Traditionally, it was performed when a king returned with his army after a successful battle..”
If you search “Dance of the Gods Tamil” for images you will find modern images of the men dancing that don’t look that different from the one above.
