It was then with the view of fundamentally reforming the literary taste of his countrymen, that Luzan wrote his celebrated Art of Poetry. It was first published at Saragossa in the year 1737, in a folio volume containing five hundred and three pages;[582] and it has ever since been the code to which Spanish critics and authors have referred for the decision of all cases of doubt. Sound judgment and classic erudition are the chief characteristics of the work. The diction too is simple and elegant, and prolixity is avoided, though in order to attain that degree of perspicuity which was necessary for subduing Spanish prejudice, much detail was indispensable. Newly discovered truths must not be looked for in Luzan’s Art of Poetry. He even claims credit for the doctrines he developes on account of their venerable antiquity. His theory is declared by himself to be in the main no other than that of Aristotle, the greatest of philosophers. To the neglect of that theory he attributes the multitude of monstrous excrescences by which Spanish literature is disfigured. He therefore conceived he was rendering, though at the risk of being reproached with pedantary,[583] an important service to the literature of his country, by the restoration and just application of those ancient and only true principles which had long been acknowledged and valued by the critics of foreign nations. In support of his doctrines, Luzan regards the critical observations of various French writers, particularly Rapin, Corneille, Crousaz, Lamy, and Madame Dacier, as next in authority to the works of Aristotle. He also availed himself of the Italian works of Gravina and Muratori. These, and other foreign authors, are quoted by name. Spanish readers must, doubtless, have been not a little surprised to find among the quotations passages from French authors, given in the French language, under the Spanish text. This was an unexampled phænomenon in Spanish literature; and though a trifling circumstance it serves to prove the increasing influence of the French language in Spain.
