Just in time for Valentine's Day, an anthropologist has unwrapped the first known evidence of
The evidence was apparently right under our noses—many of these cylinder jars have been in the Smithsonian's care ever since they were excavated in the 1890s and 1920s from the Chacoan settlement of Pueblo Bonito.
They look very similar to chocolate vessels used by Mayan cultures several hundred miles to the south. But no one knew the Chacoan jars' story for sure until University of New Mexico anthropology professor Patricia Crown followed a hunch and sent some sherds* off to a research center in Hershey, Pennsylvania (funded by a certain chocolate company you may have heard of) for analysis. Sure enough, the sherds contained traces of theobromine, a component of cacao.
From the abstract in last week's Proceedings of the National Academy of Sciences:
- The association of cylinder jars and cacao beverages suggests that the Chacoan ritual involving the drinking of cacao was tied to Mesoamerican rituals incorporating cylindrical vases and cacao.
* Just to be clear, she got the sherds from digging around the rubble at the Pueblo Bonito excavation site, not from the intact jars pictured here. The Smithsonian generally frowns on letting folks smash up its collection, even for the very worthy cause of chocolate research.
