On the Origin of the Genus Psilocybe and Its Potential Ritual Use in Ancient Africa and Europe. The role of altered states of consciousness in the production of geometric and figurative art by prehistoric cultures in Africa and Europe has been hotly debated. Helvenston and Bahn have tried to refute the most famous hypothesis, Lewis-Williams’ neuropsychological model, by claiming that appropriate visual hallucinations required the ingestion of LSD, psilocybin, or mescaline, while arguing that none of these compounds were available to the cultures in question. We present here mycological arguments that tell another story. A prehistoric worldwide distribution of the mushroom genus Psilocybe, and therefore of psilocybin, is supported by the existence of endemic species in America, Africa, and Europe, the disjunct distribution of sister species, and the possibility of long-distance spore dispersal. It is more difficult to point to instances of actual prehistoric ritual use in Africa and Europe, but there are a growing number of suggestive findings.
Sobre el Origen del Género Psilocybe y su Uso Ritual Potencial en África y Europa Antiguas. El papel de los estados alterados de conciencia en la producción de arte geométrico y figurativo por culturas prehistóricas en África y Europa ha sido fuertemente debatido. Helvenston y Bahn han tratado de refutar la hipótesis más famosa, el modelo neuropsicológico de Lewis-Williams, al afirmar que las alucinaciones visuales apropiadas requieren la ingestión de LSD, psilocibina o mezcalina, al mismo tiempo que sostienen que ninguno de estos compuestos estaba disponible para las culturas en cuestión. Presentamos aquí argumentos micológicos que cuentan una historia diferente. La distribución prehistórica mundial del hongo del género Psilocybe, y por ende de la psilocibina, es apoyada por la existencia de especies endémicas en América, África y Europa, por la distribución disyunta de especies hermanas, y por la posibilidad de dispersión de esporas a larga distancia. Es más difícil señalar ejemplos de uso ritual prehistórico reales en África y en Europa, pero hay un número creciente de hallazgos sugerentes.
