utility, takes that opportunity of expressing his opinion on the object of poetry in general, and concludes with laying down the principles of Castilian prosody. These principles appear to have been particularly useful with reference to the conflict which then subsisted between the Castilian and Limosin tongues. Among his general observations on poetry, he says--“Great are the benefits which this science confers on civil society, by banishing indolence, and employing noble minds in laudable speculations: other nations have, accordingly, wished for and established among themselves, schools of this science, by which it has been diffused over different parts of the world.”[74] It is obvious that this active nobleman was full of zeal for the improvement of the poetry of his country, and for the honour of that art which was cultivated with method and dignity in the Arragonian provinces, but which in Castile, where it was left to itself, appeared to stand in need of direction and encouragement. The difference between science and art was not more clearly perceived by the Marquis of Villena than by the other poets and men of learning of his age; and to distinguish the Castilian forms of romantic poetry from the Limosin, did not appear to him necessary. Thus, while his labours contributed to heighten the respect in which poetry and liberal pursuits were held, they had only an indirect influence on the improvement of Castilian poetry.
