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 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.
The "tale" presents a consistent satire of religious excess, while the digressions are a series of parodies of contemporary writing in literature, politics, theology, Biblical exegesis, and medicine. The overarching parody is of enthusiasm, pride, and credulity. At the time it was written, politics and religion were still closely linked in England, and the religious and political aspects of the satire can often hardly be separated. "The work made Swift notorious, and was widely misunderstood, especially by Queen Anne herself who mistook its purpose for profanity." It "effectively disbarred its author from proper preferment within the church," but is considered one of Swift's best allegories, even by himself. It was enormously popular, but Swift believed it damaged his prospect of advancement in the Church of England.
A Tale of a Tub is divided between various forms of digression and sections of a "tale". The "tale", or narrative, is an allegory of three brothers, Peter, Martin, and Jack, as they attempt to make their way in the world. Each brother represents one of the primary branches of Christianity in the West. This part of the book is a pun on "tub", which Alexander Pope says was a common term for a Dissenter's pulpit, and a reference to Swift's own position as a clergyman. Peter (named for Saint Peter) stands in for the Roman Catholic Church. Jack (named for John Calvin, but whom Swift also connects to "Jack of Leyden") represents the various dissenting Protestant churches such as Baptists, Presbyterians, Quakers, Congregationalists and Anabaptists. The third brother, middle born and middle standing, is Martin (named for Martin Luther), whom Swift uses to represent the 'via media' of the Church of England. The brothers have inherited three wonderfully satisfactory coats (representing religious practice) by their father (representing God), and they have his will (representing the Bible) to guide them. Although the will says that the brothers are forbidden from making any changes to their coats, they do nearly nothing but alter their coats from the start. In as much as the will represents the Bible and the coat represents the practice of Christianity, the allegory of the narrative is supposed to be an apology for the Anglican church's refusal to alter its practice in accordance with Puritan demands and its continued resistance to ally with the Roman church.
