A Tale of a Tub
Robert Hendrickson notes in his book "British Literary Anecdotes" that "Swift was always partial to his strikingly original "The Tale of a Tub" (1704). On reading the work again in later years, he exclaimed 'Good God! What a genius I had when I wrote that book!'"
A Tale of a Tub
Upon publication the public realised both that there was an allegory in the story of the brothers and that there were particular political references in the Digressions. A number of "Keys" appeared soon thereafter, analogous to contemporary services like CliffsNotes or Spark Notes. "Keys" offered the reader a commentary on the "Tale" and explanations of its references. Edmund Curll rushed out a "Key" to the work, and William Wotton offered up an "Answer" to the author of the work.
