One of the most humorous and effective contradictions of the popular judgment is that episode in _Njála_, where Kari has to trust to the talkative person whose wife has a low opinion of him. It begins like farce: any one can see that Bjorn has all the manners of the swaggering captain; his wife is a shrew and does not take him at his own valuation. The comedy of Bjorn is that he proves to be something different both from his own Bjorn and his wife's Bjorn. He is the idealist of his own heroism, and believes in himself as a hero. His wife knows better; but the beauty of it all is that his wife is wrong. His courage, it is true, is not quite certain, but he stands his ground; there is a small particle of a hero in him, enough to save him. His backing of Kari in the fight is what many have longed to see, who have found little comfort in the discomfiture of Bobadil and Parolles, and who will stand to it that the chronicler has done less than justice to Sir John Falstaff both at Gadshill and Shrewsbury. Never before Bjorn of _Njála_ was there seen on any theatre the person of the comfortable optimist, with a soul apparently damned from the first to a comic exposure and disgrace, but escaping this because his soul has just enough virtue to keep him steady. The ordeal of Bjorn contains more of the comic spirit than all the host of stage cowards from Pyrgopolinices to Bob Acres, precisely because it introduces something more than the simple humour, an essence more spiritual and capricious. Further, the partnership of Kari and Bjorn, and Kari's appreciation of his idealist companion, go a long way to save Kari from a too exclusive and limited devotion to the purpose of vengeance. There is much to be said on behalf of this Bjorn. His relations with Kari prevent the hero of the latter part of the book from turning into a mere hero. The humorous character of the squire brings out something new in the character of the knight, a humorous response; all which goes to increase the variety of the story, and to widen the difference between this story and all the monotonous and abstract stories of chivalrous adventures.
