It’s the tomb that keeps on giving. More than two years since its discovery, a treasure-filled Greek tomb has offered up perhaps its most significant find to date: a Minoan stone carving so sophisticated and detailed that it has forced art historians to reaccess their understanding of ancient artwork.

Dubbed the Pylos Combat Agate, the sealstone carving is just an inch and a half wide, but its impact on the study of prehistoric art may well be enormous.

“This seal should be included in all forthcoming art history texts, and will change the way that prehistoric art is viewed,” said Sharon Stocker, a senior research associate in the University of Cincinnati classics department, in a statement. She believes the stone, made by the ancient Minoans, is the finest-known example of prehistoric glyptic art produced in the Aegean Bronze Age.

The intricately carved gemstone “shows that the [Minoan’s] ability and interest in representational art, particularly movement and human anatomy, is beyond what it was imagined to be,” added her husband, department head Jack Davis, a professor of Greek archaeology. “The representation of the human body is at a level of detail and musculature that one doesn’t find again until the Classical period of Greek art 1,000 years later.”

“Looking at the image for the first time was a very moving experience, and it still is,” Stocker noted. “It’s brought some people to tears.”

The landmark find shows a warrior battling against two adversaries, killing one enemy, the other already dead at his feet.

It’s the latest archaeological treasure to come out of the Griffin Warrior Tomb, discovered by the Davis- and Stocker-led team from the University of Cincinnati at Pylos in 2015, which was touted as the most significant Greek archaeological discovery in half a century.

The tomb is believed to have been the final resting place of a remarkably wealthy Mycenaean warrior or priest. (A team of special
