The late twentieth century witnessed a great surge of Native American writing, much of which went back to tribal myth for material, for imagery, for theme, as in the case of Leslie Marmon Silko’s “Yellow Woman,” Louise Erdrich’s Kashpaw/Nanapush novels, and Gerald Vizenor’s peculiar Bearheart: The Heirship Chronicles.
I can confirm this. For my APUSH class, I read a book called Native American Testimony by Peter Nabokov, a book of many primary-source experiences as or with Native Americans. Most of the entries were from the 1900’s.
