The Life of John Bunyan, Written by Himself, and Published under the Title of ‘Grace Abounding to the Chief of Sinners’. With the Addition of Some Particulars of His Examination before His Committal to Prison, and a Continuation to the Time He Joined Good

Though known to members of his community by the nickname "Bishop Bunyan," the author of The Pilgrim's Progress was actually a member of a Puritan sect that shunned the concept of religious authority. Bunyan's skills as a lay preacher were considerable; after the Restoration, he landed in jail for refusing to comply with Church of England regulations. His religious fervor and propensity for exaggeration have been described by twentieth-century psychologists as bordering on psychopathic obsession.
