Where the Gods Reign is a complete anthropological overview of the Amazon rainforest ecosystem, containing chapters on rivers, ethnic groups, cultural activities, rubber and coca plants, drugs and medicines, and others. Beautiful photographs taken by Dr. Schultes during the '40s and '50s are accompanied by explanatory text, providing a vivid illustration of the evolutionary relationship between mankind and the biomes within which we live. Richard Evans Schultes is considered the father of modern ethnobotany and this text, a companion to Vine of the Soul, is a classic in the field.
