(Since the early 1970s, a legend of Rainbow Warriors has inspired some environmentalists in the United States with a belief that their movement is the fulfillment of a Native American prophecy. Usually the story is claimed to be Hopi or Cree. However, the origin of the “prophecy” is not Native American at all, but rather from a 1962 book titled Warriors of the Rainbow by William Willoya and Vinson Brown from Naturegraph Publishers. Brown, who is attributed with research into Hopi prophecies, is the founder and owner of Naturegraph Publishers)
