It is stated by Pope in his prefatory advertisement that the House of Fame had only supplied him with the "hint" for the Temple of Fame, that "the design was entirely altered," and that "the descriptions, and most of the particular thoughts, were his own." Bowles says that "Pope seems unwilling to confess all he owes to Chaucer," and that his language would "lead us to conclude that the chief merit of the arrangement and imagination belonged to himself," whereas he is indebted to his predecessor for "what is most poetical in the whole composition." Pope cannot be accused of concealing his obligations to the House of Fame, for he has fairly specified them in his notes, but he extremely underrated the extent to which he borrowed from it when he fancied that his general outline was different, and "most of the particular thoughts entirely new." The fertility of invention ascribed to him by Roscoe, and which he, in some degree, challenges for himself, is the last praise he can claim. Every portion of the conception which has a touch of creative power is found in Chaucer, together with the largest part of what is good in the filling up. High authorities differ as to the effect of Pope's additions and variations. Thomas Warton pronounced that "the character of the poem was marred," and Bowles endorsed the criticism. Johnson, on the other hand, asserts that "the original vision was never denied to be much improved," and he had Joseph Warton, Roscoe, and Campbell on his side. "Much of Chaucer's fantastic matter," says Campbell, "has been judiciously omitted by Pope, who at the same time has clothed the best ideas of the old poem in spirited numbers and expression. Chaucer supposes himself to be snatched up to heaven by a large eagle, who addresses him in the name of St. James and the Virgin Mary. In Pope, the philosophy of fame comes with much more propriety from the poet himself than from the beak of a talkative eagle."[5] The introduction of the majestic eagle, its tremendous swoop when it pounces on the lonely wanderer, the terror produced by the first stage of the flight, and the animated dialogue in the second stage, is the most striking portion of Chaucer's vision. The philosophic discourse of the bird is not inconsistent with the wild imaginings of a dream. "Fantastic matter" is here the most natural, and keeps up an illusion which disappears in the formal composition of Pope. The advantage of modern language and versification would have rendered it easy for a man less gifted than him to improve on isolated passages, but the free fancy and picturesqueness of Chaucer are wanting. The romance which constitutes the truth and charm of the original dream is replaced by a scene of frigid tameness; and Johnson, while declaring that every part of the remodelled piece was splendid, is compelled to admit that it is turned silently over and takes no hold on the mind. Dullness is a fatal innovation which is poorly compensated by the greater polish of the style, and harmony of the verse.
