Based on more than 24 months of ethnographic research among Maya ritualists in the western highlands of Guatemala, this article examines howpajooneem, ortz’ite’seed divination, facilitates decision-making and distributes cognition between client, diviner, and ritual techniques.Tz’ite’seed divination exhibits a stylized routine that draws on important ‘mediating structures,’ including the 260-day ritual calendar known throughout Mesoamerica. Because it is both a ritual and cognitive practice, Maya divination grounds decision-making in a perennially relevant set of cultural values.
