Oldest known painting of a Maya mythical hero found at Calakmul

Researchers at the ancient Maya city of Calakmul are now saying a mural once interpreted as a generic warrior holding a spear may actually depict Juun Ajaw, a mythical hunter who is central to Maya storytelling. If confirmed, it could be the earliest known image of that figure. What gets me is imagining the hand that painted it, the brushwork decisions someone made on wet plaster centuries ago to convey a specific story. Every mark was intentional. It's a reminder that draftsmanship has always been inseparable from narrative. Has anyone else studied ancient mural techniques or tried to learn from how early artists handled line and composition on that scale?
