Because of its explicit English Protestant theology "The Pilgrim's Progress" shares the feeling of most English, in the 17th century, against the Roman Catholic Church. It was published over the years of the Popish Plot (1678–1681) and ten years before the Glorious Revolution of 1688, and it shows the influence of John Foxe's "Foxe's Book of Martyrs". Bunyan presents a decrepit and harmless giant to confront Christian at the end of the Valley of the Shadow of Death that is explicitly named "Pope":Now I saw in my Dream, that at the end of this Valley lay blood, bones, ashes, and mangled bodies of men, even of Pilgrims that had gone this way formerly: And while I was musing what should be the reason, I espied a little before me a Cave, where two Giants, "Pope" and "Pagan", dwelt in old times, by whose Power and Tyranny the Men whose bones, blood ashes, &c. lay there, were cruelly put to death. But by this place "Christian" went without much danger, whereat I somewhat wondered; but I have learnt since, that "Pagan" has been dead many a day; and as for the other, though he be yet alive, he is by reason of age, and also of the many shrewd brushes that he met with in his younger dayes, grown so crazy and stiff in his joynts, that he can now do little more than sit in his Caves mouth, grinning at Pilgrims as they go by, and biting his nails, because he cannot come at them.
