Where did the phrase 'once in a blue moon' come from? A folklorist traces the convoluted evolution of the phrase, while discussing why it adopted the many meanings it has throughout history.
âOnce in a blue moonâ today means âvery rarely,â though it used to mean something that was absurd, right along the lines of âwhen pigs fly.â The first known recorded use of a form of the phrase is in an anti-clerical pamphlet published in 1528 by William Roy and Jeremy Barlowe.
