When does it appear
In the month of August in the year 1891 the kāhili and the pūloʻu were seen by a man in his dream. In that dream he saw an aliʻi perched precariously inside a large kāhili rainbow above Iolani palace. At that very moment, the aliʻi fell and that man that was dreaming awoke with a start. The man understood this dream, and he thought, this dream was a sign for the falling of a ruling chief, or a time of overthrow that was coming. In 16 months later after the printing of the newspaper article about his dream, the Hawaiian government was fraudulently overthrown by some missionaries and greedy American businessmen (Unknown author 1891).
