“But this fault is rare in Bunyan — far rarer than in Piers Plowman. If such dead wood were removed from The Pilgrim’s Progress the book would not be very much shorter than it is. The greater part of it is enthralling narrative or genuinely dramatic dialogue. Bunyan stands with Malory and Trollope as a master of perfect naturalness in the mimesis of ordinary conversation” (C.S. Lewis, Selected Literary Essays, p. 146).
