EUROPEANS may have used magic mushrooms to liven up religious rituals 6000 years ago. So suggests a cave mural in Spain, which may depict fungi with hallucinogenic properties - the oldest evidence of their use in Europe.
The Selva Pascuala mural, in a cave near the town of Villar del Humo, is dominated by a bull. But it is a row of 13 small mushroom-like objects that interests Brian Akers at Pasco-Hernando Community College in New Port Richey, Florida, and Gaston Guzman at the Ecological Institute of Xalapa in Mexico. They believe that the objects are the fungi Psilocybe hispanica , a local species with hallucinogenic properties.
