In Black Elk Speaks and When the Tree Flowered, John C Neihardt recorded the teachings of the Oglala holy man Black Elk, who had, in a vision, seen himself as the sixth grandfather, the spiritual representative of the earth and of mankind. Raymond J. DeMallie makes available for the first time the transcripts from Neihardt's interviews with Black Elk in 1931 and 1944, which formed the basis for the two books. His introduction offers new insights into the life of Black Elk.
Lakota Belief and Ritual presents the James R. Walker collection of traditional Lakota knowledge. Walker spent eighteen years in South Dakota as a physician on the Pine Ridge Reservation, the home of the Oglala Sioux. From 1896 until 1914, he collected material relating to nearly every aspect of the old Lakota way of life. This collection records teachings by men whose statements of belief show the energy, depth, and imaginative intensity characteristic of the Lakota response to specific cultural, social, and ecological challenges.
