Leslie Marmon Silko published a critique of Gary Snyder’s Turtle Island in a 1977 issue of the Yardbird Reader. 1977 is the year she published her first novel Ceremony. And Yardbird Reader was a literary journal founded in 1972 by Ishmael Reed — a yearly anthology featuring writing by contemporary authors of color. Several of the writers I’m teaching this semester, in other words, wrote in dialogue with one another over the course of the 1970s. Silko titled her critique of Snyder “An Old-Time Indian Attack Conducted in Two Parts.”
