John Brown's biography of John Bunyan remains the standard, despite the lapse of over 100 years since it was first published. The author was one of Bunyan's successors as minister of the church in Bedford. He shows that many of the scenes familiar to readers of Pilgrim's Progress reflect local places and events and personal experience in the trials and joys of the Christian life.
I greatly admire Bunyan but this work was not at all provocative, interesting or very well told. Did not finish.
