Handsome Lake (1735-1815) was a religious reformer among the Iroquois, the prominent alliance of New York tribes. His 'Code', presented in this book in full, attempted to simplify the spiritual practices of the Iroquois, preaching temperance, a strict moral code, and self-determination. It also contains some startling prophecies: Handsome Lake believed the world would end (by fire) in the year 2100; he predicted the destruction of the environment, famines, and war; and one of his visions (see section 93) appears to describe the destruction of the ozone layer. This book also contains invaluable descriptions of Iroquois religious rituals and myths at the turn of the twentieth Century.
