This is the Denver-resident half of a pair of panels, which together tell a story of the still-lost Maya kingdom of Sak Tz’i’ (White Dog). We know the name of the site from inscriptions on the panels, it was once one of a number of kingdoms that battled along today’s Guatemala – Mexico border. But while we know the site’s name, and the rough area in which it was located (since its name glyph appears throughout the area), no one knows the location of Sak Tz’i’.
Such is the ambivalent nature of many ancient artifacts you can see in museums today. You get to see the artifacts, but many were ultimately purchased from looters (and by continuing such purchases, museums in the more-affluent parts of the world perpetuate the vicious cycle). By removing the panels from their original site, looters destroyed evidence about the site’s history.
Seen at the Maya: Hidden Worlds Revealed exhibit at the Denver Museum of Nature and Science.
