WASHINGTON, D.C.—A tunic, or unku, once worn by an Inca man has been recovered from a grave in northern Chile, according to a statement released by George Washington University. Unkus were made according to specifications imposed by imperial authorities, said team member Jeffrey Splitstoser of George Washington University. This unku, however, also has features unique to the provincial region where it was found, hundreds of miles south of Cusco, the Inca capital. “It represents a study of a rare example of an excavated Inca unku tunic, whose context and technical features are providing an unprecedented understanding of imperial Inca influence in the provinces,” Splitstoser explained.
