Far-flung exchanges may have involved turquoise for cacao
Chocolate may have provided sweet impetus for extensive trade between ancient northern and southern societies in the Americas. Pueblo people living in what’s now the U.S. Southwest drank a cacao-based beverage that was imported from Mesoamerican cultures in southern Mexico or Central America, a new chemical analysis of Pueblo vessels finds.
Pueblo groups and an ensuing Southwest society traded turquoise for Mesoamerican cacao for about five centuries, from around 900 to 1400, proposes a team led by archaeologist Dorothy Washburn of the University of Pennsylvania in Philadelphia. Surprisingly, large numbers of people throughout Pueblo society apparently consumed cacao, from low-ranking farmers to elite residents of a multistory pueblo, the scientists report online March 4 in the Journal of Archaeological Science.
