All that you have to do is make proper use of imitation in what you write, and the more perfect the imitation the better will your writing be. Inasmuch as you have no other object in view than that of overthrowing the authority and prestige which books of chivalry enjoy in the world at large and among the vulgar, there is no reason why you should go begging maxims of the philosophers, counsels of Holy Writ, fables of the poets, orations of the rhetoricians, or miracles of the saints; see to it, rather, that your style flows along smoothly, pleasingly, and sonorously, and that your words are the proper ones, meaningful and well placed, expressive of your intention in setting them down and of what you wish to say, without any intricacy or obscurity. Let it be your aim that, by reading your story, the melancholy may be moved to laughter and the cheerful man made merrier still; let the simple not be bored, but may the clever admire your originality; let the grave ones not despise you, but let the prudent praise you. And keep in mind, above all, your purpose, which is that of undermining the ill-founded edifice that is constituted by those books of chivalry, so abhorred by many but admired by many more; if you succeed in attaining it, you will have accomplished no little.
