The Pilgrim’s Progress from This World to That Which Is to Come. Delivered under the Similitude of a Dream. In Two Parts. With Two Hundred and Seventy Engravings, from Entirely New Designs

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.
