In Frank Waters's writings on Hopi mythology, the Blue Star Kachina or Saquasohuh, is a kachina or spirit, that will signify the coming of the beginning of the new world by appearing in the form of a blue star. The Blue Star Kachina is said to be the ninth and final sign before the "Day of Purification", described as an apocalypse or a "world engulfing cataclysm" that will lead to the destruction of the world.[1] Author Jason Colavito investigated this prophecy and found no reference to it before the late twentieth century.[2]
