PARIS — Octavius Seowtewa, an elder of the Native American Zuni tribe from New Mexico, was sitting in a Paris cafe late last month, scrolling through his iPhone pictures of Ahayuda, carved and decorated wooden poles that are considered sacred to the Zuni. They were taken at his recent meetings with representatives of major European museums, whom he is hoping he can persuade to return the artifacts.

Mr. Seowtewa, who exudes a quiet persistence and was dressed that day in a black leather blazer, dark slacks and a button-down shirt, acknowledged that he hadn’t had much luck in his meetings at the Musée du Quai Branly here or at the Ethnological Museum in Berlin, among others. But he said he was just getting started.

Since 1978, the Zuni have been more proactive than other Native American tribes in reclaiming ceremonial objects: in their case, more than 100 Ahayuda, also called war gods, from institutions and collections in the United States. The Zuni have taken advantage of federal legislation that requires all United States institutions to return objects considered sacred by Native Americans to individual tribes or risk losing federal funding. But those laws do not apply in Europe. Here, the Zuni case is a moral one. “That’s all there is,” Mr. Seowtewa said. “We believe if you listen to us about the power these objects have to our community, that these are exemplars of sacred objects, of communally owned objects,” then museums will consider sending them back, he added.

Mr. Seowtewa said the Zuni wanted back only the Ahayuda and are not asking for other artifacts, including pottery and beads.
