Metates and Hallucinogens in Costa Rica

Abstract

Metates are grinding stones on which corn and other substances are ground with hand-held stones called manos. A clue that grinding stones were associated with mushroom rituals is, for example, provided by a tripod metate from NW Costa Rica belonging to the period of the 2nd or 3rd century AD.
