In Holy War, John Bunyan was an English preacher, but today he's most famous for writing the seminal Pilgrim's Progress, one of history's most famous and popular allegorical works. Bunyan even has a festival in his honor within the Church of England.Though not as popular as Pilgrim's Progress, this allegorical novel relates the story of the town "Mansoul", a perfect place that replaces its beneficient ruler with Diabolus. The allegory's distinction between God and Satan is obvious.
