John Bunyan wrote this of the antagonists that Christian ran across on his journey.

“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, 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.”
