could have befallenChaucer than that he should have been christened "the father ofEnglish Line poetry." For "father" in such a context conveys to (5) most of us, I fear, a faint suggestion of vicarious glory—the derivative celebrity of parents, other- wise obscure, who shine, moon-like, in the reflected luster of their sons. What else than progenitors were the fathers of Plato, orCaesar, (10) or Shakespeare, or NapoleonAnd so to call Chaucer the father ofEnglish poetry is often tan- tamount to dismissing him, not unkindly, as the estimable but archaic ancestor of a brilliant line. ButChaucer—if I may risk the paradox—is him- (15) self the very thing he begat. He isEnglish poetry incarnate, and only two, perhaps, of all his sons outshine his fame. It is withChaucer himself, then, and not save incidentally with his ancestral eminence that we shall be concerneD、 (20)But five hundred and thirty-three years have passed sinceChaucer dieD、And to overleap five centuries is to find ourselves in another world, a world at once familiar and strange. Its determin- ing concepts are implicit in all thatChaucer, who (25) was of it, thought and wrote.And, woven as they are into his web, they at once lend to it and gain from it flesh significance. To us they are obso- lete; in theCanterbury Tales, and the Troilus, and the House of Fame they are current and alive. (30)And it is in their habit as they lived, and not as mere curious lore, that I mean to deal with them. Let me begin with the very tongue which Chaucer spoke—a speech at once our own and not our own. "You know," he wrote—and for the (35) moment I rudely modernize lines as liquid in their rhythm as smooth-sliding brandy—"you know that in a thousand years there is change in the forms of speech, and words which were then judged apt and choice now seem to us wondrous (40) quaint and strange, and yet they spoke them so, and managed as well in love with them as men now do."And to us, after only half a thousand years, those very lines are an embodiment of what they state: (45) Ye knowe eek, that in forme of speche is chaunge Withinne a thousand yeer, and words tho That hadden prys, now wonder nyce and straunge (50)Us thinketh hem; and yet they spake hem so, And spedde as wel in love as men now do. But it is not onlyChaucer’s speech which has undergone transformation. The change in his world is greater still.And the situation which (55) confronts us is this. InChancer’s greatest work we have to do with timeless creations upon a time-determined stage.And it is one of the inescapable ironies of time that creations of the imagination which are at once of no time and for (60) all time must nevertheless think and speak and act in terms and in ways which are as transient as they themselves are permanent. Their world—the stage on which they play their parts, and in terms of which they think—has become within a few (65) lifetimes strange and obsolete, and must be deci- phered before it can be reaD、For the immortal puts on mortality when great conceptions are clothed in the only garment ever possible—in terms whose import and associations are fixed by (70) the form and pressure of an in
