In 1660 the revival under the Restoration government of obsolete enactments against conventicles, with no endeavour to discriminate between seditious conspirators like the Fifth Monarchy men and harmless worshippers like the Baptists, compelled the reluctant Bedford magistrates to arrest and imprison Bunyan as an unlicensed preacher. He might have escaped, or have obtained release by a trifling submission, but with the spirit of a Christian martyr he disdained either course, and abode contentedly in prison for nearly twelve years. His captivity in the commodious county gaol was by no means oppressive; indeed, in the first part of it he enjoyed a large measure of liberty, afterwards withdrawn. He supported himself by making tagged laces, as well as by the publication of some books, of which _Grace Abounding_ (1666) is the most important. The first part of _Pilgrim's Progress_ was also written in prison, but, as Bunyan's best biographer, Dr. John Brown, almost proves, during a second and comparatively brief confinement in 1676. In 1672 Bunyan published his _Defence of Justification by Faith_, a coarse and violent attack on the _Design of Christianity_, by Dr., afterwards Bishop Fowler, one of the most tolerant divines of the age, but who was provoked to reply with almost equal acrimony. In the same year Charles II.'s merciful but entirely illegal suspension of all statutes against Papists and Nonconformists liberated Bunyan, who even obtained a licence to preach, and became stated minister of the Baptist congregation at Bedford, then meeting in a barn in an orchard. Notwithstanding some few molestations, of which the second imprisonment in 1675-76 was the chief, the remainder of his life was in general tranquil and prosperous. The first part of _Pilgrim's Progress_ appeared in 1678, and, though not half-a-dozen copies of it are now known to exist, immediately attained the highest popularity. Edition followed edition, the first two or three with remarkable additions and improvements. Bunyan frequently visited London, where he became a popular preacher; his influence was courted, though unsuccessfully, by the government itself, and in 1688, the year of his death, he had become in some sort chaplain to the Lord Mayor, 'an Anabaptist, a very odd ignorant person,' says Evelyn. His principal works in the interval had been: _The Life and Death of Mr. Badman_, 1680; _The Holy War_, 1682; the second part of the _Pilgrim's Progress_, 1684; _The Jerusalem Sinner Saved_, 1688. His death, on August 31st, 1688, took place in London, and was occasioned by cold contracted on a journey which he had undertaken to reconcile a father with his son.
