Book excerpt: Native Americans believed that it was their responsibility to maintain harmony in the natural world on which they depended by performing a variety of rituals. Shamans were credited with exceptional powers to act on behalf of the community. They claimed to be capable of separating their spirits from their bodies and interceding with those spirits that controlled the many forces of nature. Having studied the subject at first hand during his many visits to American tribes, Dr. Norman Bancroft Hunt sets out the richly rewarding results of his research in this survey of shamanic traditions and practices in various Native American groups. Shamanism in North America is profusely illustrated with the most remarkable masks, effigies, and implements used by shamans and includes evocative images of the often harsh wilderness inhabited by the tribes under discussion, as well as some revealing historical photographs of shamans.
