A Tale of a Tub
A Tale of a Tub was the first major work written by Jonathan Swift, arguably his most difficult satire and perhaps his most masterly. The "Tale" is a prose parody divided into sections each delving into the morals and ethics of the English. Composed between 1694 and 1697, it was eventually published in 1704. It was long regarded as a satire on religion, and has famously been attacked for that, starting with William Wotton.

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.
