It would be hard to imagine a more misleading title than “Fiercely Modern: Art of the Naga Warrior,” the name of a show at the Rubin Museum of Art. The Naga, a diverse collection of peoples speaking similar languages and residing in a mountainous area in northeastern India, certainly were fierce. Headhunting was one of their prized pursuits. But they were far from modern by present-day standards. In fact, the culture of the Naga was nearly destroyed by modern Europeans. First came mid-19-century subjugation by the British, who wanted to stop the irritation of headhunting raids on neighboring Indian territories. Then American Baptist missionaries invaded, eventually succeeding in almost totally suppressing the Naga’s “satanic” practices and converting nearly all of the population to nominal Christianity.
