Piedras Negras (Pyramid K-5) was one of the most powerful Maya kingdoms of the Classic period, famous for its extraordinary carved stelae and thrones — Panel 3 is considered among the finest Maya sculptural achievements ever created. The site engaged in a centuries-long rivalry with Yaxchilan across the Usumacinta River. Tatiana Proskouriakoff's groundbreaking 1960 study of Piedras Negras stelae proved that Maya inscriptions recorded historical events, not purely astronomical data — revolutionizing Maya epigraphy. At 49.97° Giza bearing, the site anchors the western edge of the Peten pyramid corridor.
