Aristotle, his notions respecting the different poetic styles are as confused as those of his contemporaries; and only a few of his notions and distinctions can be deemed of importance at the present day. But his name is deserving of honourable remembrance, for he was the first writer of modern times who endeavoured to establish a philosophic art of poetry; and with all his veneration for Aristotle, he was the first scholar who ventured to think for himself, and to go somewhat further than his master. He also evinced a laudable perseverance in the execution of his task. Pinciano’s learned and ingenious work was not quite so useful as it might have been, owing in a great measure to its artificial and formal manner of composition, which, however, the author considered singularly easy and natural. This Art of Poetry is written in the form of letters, (which was in itself a novelty at that age), and in these letters, conversations are occasionally introduced. The friend who answers, invariably gives an abstract of the letter he has last received, as a proof that he understands its contents and its object. Lopez Pinciano, however, cannot be regarded as a model in epistolary and conversational prose any more than in poetry. The authors of the other arts of poetry which appeared about this time in the Spanish language, merely confined themselves to the explanation of metrical forms and the establishment of subordinate principles. Among these authors were Sanchez de Viena, Geronymo de Mondragon, and Juan Diaz.[329] An Art of Poetry of the same description in verse, by Juan de la Cueva, has already been mentioned. From a philosophic treatise of this kind, Spanish poetry could derive no advantage, unless its origin had been totally different from what it really was. Theories, even the most popular, can contribute only in a very slight degree to the formation of the poetic genius, either of nations or individuals. Several works on the art of rhetoric, in which the principles of Aristotle were followed, appeared about this time in Spain; but they produced nothing valuable with respect to theory, and exercised no remarkable influence on the improvement of Spanish prose.
