For the better exposure of these mad fancies Cervantes has not only put them into action in real life, but contrasted them with another character which may be said to form the reverse side of his hero's. Honest Sancho represents the material principle as perfectly as his master does the intellectual or ideal. He is of the earth, earthy. Sly, selfish, sensual, his dreams are not of glory, but of good feeding. His only concern is for his carcass. His notions of honor appear to be much the same with those of his jovial contemporary Falstaff, as conveyed in his memorable soliloquy. In the sublime night-piece which ends with the fulling-mills--truly sublime until we reach the denouement--Sancho asks his master: "Why need you go about this adventure? It is main dark, and there is never a living soul sees us; we have nothing to do but to sheer off and get out of harm's way. Who is there to take notice of our flinching?" Can anything be imagined more exquisitely opposed to the true spirit of chivalry? The whole compass of fiction nowhere displays the power of contrast so forcibly as in these two characters; perfectly opposed to each other, not only in their minds and general habits, but in the minutest details of personal appearance. It was a great effort of art for Cervantes to maintain the dignity of his hero's character in the midst of the whimsical and ridiculous distresses in which he has perpetually involved him. His infirmity leads us to distinguish between his character and his conduct, and to absolve him from all responsibility for the latter. The author's art is no less shown in regard to the other principal figure in the piece, Sancho Panza, who, with the most contemptible qualities, contrives to keep a strong hold on our interest by the kindness of his nature and his shrewd understanding. He is far too shrewd a person, indeed, to make it natural for him to have followed so crack-brained a master unless bribed by the promise of a substantial recompense. He is a personification, as it were, of the popular wisdom--a "bundle of proverbs," as his master somewhere styles him; and proverbs are the most compact form in which the wisdom of a people is digested. They have been collected into several distinct works in Spain, where they exceed in number those of any other, if not every other country in Europe. As many of them are of great antiquity, they are of inestimable price with the Castilian jurists, as affording rich samples of obsolete idioms and the various mutations of the language.
