A 1856 work by Henry Rowe Schoolcraft, an American geographer, geologist, and ethnologist, noted for his early studies of Native American cultures. “Hitherto, Indian opinion, on abstract subjects, has been a sealed book. It has been impossible to extract the truth from his evasive replies. If asked his opinion of religion in the abstract, he knows not the true meaning of the term. His ideas of the existence of a Deity are vague, at best; and the lines of separation between it and necromancy, medical magic, and demonology are too faintly separated to allow him to speak with discrimination. The best reply, as to his religious views, his mythology, his cosmogony, and his general views as to the mode and manifestations of the government and providences of God, are to be found in his myths and legends.”
