"On April 12 the Néret-Minet auction house in Paris will auction many sacred Hopi artifacts, over the objections of the tribe. But while American officials frequently work with foreign nations to return antiquities, Washington has no reciprocal agreements governing American artifacts abroad... tribes reaching overseas to recover items that they view as culturally important are left to do battle on their own.
The Hopis, who number about 18,000 in northeast Arizona, believe the objects in the Paris sale, which they call Katsinam, or ‘friends,’ are imbued with divine spirits. The brightly colored visages and headdresses, often adorned with horsehair, sheepskin, feathers and maize, are thought to embody the spirits of warriors, animals, messengers, fire, rain and clouds, among other things. They are used today, as in the past, in many Hopi rites, like coming-of-age ceremonies and harvest rituals."
