The dance depicted  has pre-Columbian origins. Believed to be originally a dance to honor the sun, thunder and rain gods, the costumes are markers of importance. The now-extinct Q'a bird was used to create the elaborate headdresses because of the birds' vibrant plumage. Vintage Aztec/Mayan Copper Plaque Depicting a Dance to Honor the Sun Very Interesting piece Patina is as we acquired it.  Very uncommon find.  Thank you.
