Archaeology magazine highlighted the work of an international research team led by the University of Cincinnati that used environmental DNA to unlock the secrets of ancient Mayan culture.
UC College of Arts and Sciences Professor David Lentz told the magazine that a DNA analysis of a stained section of ground at the base of a Maya ballcourt revealed the surprising discovery of possible ritual blessings at the important landmark in the city of Yaxnohcah.
Researchers said the ancient Maya likely made a ceremonial offering during the ballcourt's construction.
Environmental DNA from the site came from, among other plants, a tree called jool, the bark of which is used in ceremonial wrappings, and xtabentun, a plant with hallucinogenic properties also used in rituals.
The research was carried out through Mexico's National Institute of Anthropology and History in collaboration with researchers from the University of Calgary, the Autonomous University of Campeche and the National Autonomous University of Mexico.
Lentz and his research partners have been studying ancient Mesoamerican cultures across Mexico and Central America. New tools that can identify environmental DNA are helping them unlock secrets about how the ancient Maya might have used these spaces.
The ancient Maya played several ball games, including pok-a-tok, which was a mix of soccer and basketball. Players tried to get a ball through a ring or hoop on a wall.
"Ballcourts occupied prime real estate in the ceremonial center," Lentz said. "They were a fundamental part of the city."
Now UC researchers hope to apply similar environmental DNA techniques to excavations at the ancient Maya city of Calakmul, about 10 miles north of Yaxnohcah, where lidar surveys have identified previously unknown agricultural terraces.
"We're about to get a completely new picture of how the Maya fed themselves," he told the magazine.
