Works Between 1656, when he published his first work, Some Gospel Truths Opened (a tract against the Ranters and Quakers—who at the time were somewhat indistinguishable), and his death in 1688, Bunyan published 42 titles. A further two works, including his Last Sermon, were published the following year by George Larkin. In 1692 Southwark comb-maker Charles Doe, who was a friend of Bunyan's in his later years, brought out, with the collaboration of Bunyan's widow, a collection of the author's works, including 12 previously unpublished titles, mostly sermons. Six years later Doe published The Heavenly Footman and finally in 1765 Relation of My Imprisonment was published, giving a total of 58 published titles. It is the allegory The Pilgrim's Progress, written during Bunyan's twelve-year imprisonment although not published until 1678 (six years after his release), that made Bunyan's name as an author with its immediate success. It remains the book for which Bunyan is best remembered. The images Bunyan uses in The Pilgrim's Progress are reflections of images from his own world: the strait gate is a version of the wicket gate at Elstow Abbey church; the Slough of Despond is a reflection of Squitch Fen, a wet and mossy area near his cottage in Harrowden; the Delectable Mountains are an image of the Chiltern Hills surrounding Bedfordshire. Even his characters, like the Evangelist as influenced by John Gifford, are reflections of real people. Further allegorical works were to follow: The Life and Death of Mr. Badman (1680), The Holy War (1682), and Pilgrim's Progress Part II (1684). Grace Abounding to the Chief of Sinners, a spiritual autobiography, was published in 1666, when he was still in prison. Memorials There is a small obelisk marking his birthplace in a field beside 'Bumpy Lane', which is in between the village of Elstow and Old Harrowden Lane. In 1862 a recumbent statue was created to adorn Bunyan's grave; it was restored in 1922. In 1874, a bronze statue of John Bunyan, sculpted by Sir Joseph Edgar Boehm, was erected in Bedford. This stands at the south-western corner of St Peter's Green, facing Bedford's High Street. The site was chosen by Boehm for its significance as a crossroads. Bunyan is depicted expounding the Bible, to an invisible congregation, with a broken fetter representing his imprisonment by his left foot. There are three scenes from
