To handle the tricky art of figuring out the painting’s age, they got creative and turned to radiocarbon dating of mud wasp nests. 

Radiocarbon dating lets scientist make age estimates for organic materials. The location of several wasp nests both under and over the pigment made it possible to dial in when it was created.

The painting was found on
