That John Bunyan had read at least the first book of Spenser's Faerie Queene, and had transformed certain adventures of the Red Cross Knight into the adventures of his own hero in Pilgrim's Progress, is a statement which has been frequently made. And, indeed, the idea has much reason on its side. The parallel between a series of incidents in Spenser's first book and a series in Pilgrim's Progress is fully as close as many another which has been held sufficient to establish a literary relationship. To Spenser's House of Holinesse, with its porter, its four grave damsels, its sober entertainment of the knight, corresponds Bunyan's House Beautiful. To the closing episode of the Red Cross Knight's sojourn at the House of Holinesse, his sight of the pilgrim's road and of Hierusalem from the near-by Mount of Contemplation, corresponds the view which Christian, from the top of the House Beautiful, has of the Delectable Mountains, from which, in the course of the story, he is to see the Celestial City itself. To the immediately succeeding conflict with the dragon, to the monster's fiery breath and horrid shrieks, to the hero's distress and eventual triumph, and particularly to the miraculous restoration of the wounded knight through the agency of the Tree of Life, corresponds Christian's battle with Apollyon, fought in the Valley of Humiliation, just after he has parted from the damsels of the House Beautiful. When to the parallel between these series of incidents in The Faerie Queene and in Pilgrim's Progress is added a certain similarity between the allegorical significances of these incidents, as well as a much more doubtful likeness between Spenser's Despair and the Giant Despair of Bunyan, some sort of relationship between the earlier and the later author appears evident enough.
