John Bunyan wrote may other works of fiction and nonfiction, including his autobiography, Grace Abounding to the Chief of Sinners, and novels The Holy War and The Life and Death of Mr. Badman.
The twentieth-century Christian writer C.S. Lewis published Pilgrim's Regress in 1933, an allegory inspired by Bunyan's work but set in Lewis's context.
Pilgrim's Progress had a profound influence on English literature, and there are clear allusions to it in works like Robinson Crusoe (1791) and the title of William Makepeace Thackeray's Vanity Fair (1847).
