1. You command me, noble spirits, flower of Spain,--who in this congress and renowned academy will in short space of time surpass not only the assemblies of Italy which Cicero, envious of Greece, made famous with his own name, hard by the Lake of Avernus, but also Athens where in the Lyceum of Plato was seen high conclave of philosophers,--to write you an art of the play which is today acceptable to the taste of the crowd. 2. Easy seems this subject, and easy it would be for anyone of you who had written very few comedies, and who knows more about the art of writing them and of all these things; for what condemns me in this task is that I have written them without art. 3. Not because I was ignorant of the precepts; thank God, even while I was a tyro in grammar, I went through the books which treated the subject, before I had seen the sun run its course ten times from the Ram to the Fishes; 4. But because, in fine, I found that comedies were not at that time, in Spain, as their first devisers in the world thought that they should be written; but rather as many rude fellows managed them; who confirmed the crowd in its own crudeness; and so they were introduced in such wise that he who now writes them artistically dies without fame and guerdon; for custom can do more among those who lack light of art than reason and force. 5. True it is that I have sometimes written in accordance with the art which few know; but, no sooner do I see coming from some other source the monstrosities full of painted scenes where the crowd congregates and the women who canonize this sad business, than I return to that same barbarous habit, and when I have to write a comedy I lock in the precepts with six keys, I banish Terence and Plautus from my study that they may not cry out at me; for truth, even in dumb books, is wont to call aloud; and I write in accordance with that art which they devised who aspired to the applause of the crowd; for, since the crowd pays for the comedies, it is fitting to talk foolishly to it to satisfy its taste. 6. Yet true comedy has its end established like every kind of poem or poetic art, and that has always been to imitate the actions of men and to paint the customs of their age. Furthermore, all poetic imitation whatsoever is composed of three things, which are discourse, agreeable verse, harmony, that is to say music, which so far was common also to tragedy; comedy being different from tragedy in that it treats of lowly and plebeian actions, and tragedy of royal and great ones. Look whether there be in our comedies few failings.
