The term 'romance' is not an exact one. Applied to medieval writings it denotes a large area whose outer limits are by no means easy to define. Yet most readers of English literature have some notion of what a typical romance is like, a notion derived mainly from the tales of Arthur and the Round Table. The hero of such a romance will be a knight who engages in perilous adventures, riding out and frequently fighting, sometimes to win or defend a lady, sometimes to defeat enemies of the realm, and sometimes for no evident reason at all. It should be said straightaway that the reader who turns to Chaucer's great story-collection in search of such a typical romance will be disappointed; for the five Canterbury 'romances' to be discussed in this chapter are all, in one way or another, divergent from that stereotype. It is as if Chaucer, who seems so much at home in the fabliau, the miracle of the Virgin, and the saint's life, felt less easy with the very genre which we regard as most characteristic of his period, the knightly romance.
