The Pilgrim's Progress is one of the most influential religious works in English literature. It was written by John Bunyan (1628-1688), a Puritan who was imprisoned for holding religious services outside the established Church of England. Bunyan, a tinker by trade and preacher by calling, began writing this Christian allegory during his twelve-year imprisonment in Bedford jail (1660-1672), though it wasn't published until 1678. We are proud to bring this book to life by refreshing the language to better suit modern readers.
