Velazquez was a man of talent and industry, rather than a man of genius. He was a member, not only of the principal Spanish academies, but of the French Academy of Inscriptions and Belles Lettres, and wrote several works of learning relating to the literature and antiquities of his country. The only one of them now much valued was published in 1754, under the title of “Sources of Castilian Poetry,” of which it is, in fact, a history, coming down to his own times, or near to them. It is a slight work, confused in its arrangement, and too short to develope its subject satisfactorily; but it is written in a good style, and occasionally shows acuteness in its criticism of individual authors. Its chief fault is, that it is devoted to the French school, and is an attempt to carry out, by means of an historical discussion, the doctrines laid down nearly twenty years before by Luzan, in his theory of poetical composition.[317] [317] Luis Joseph Velazquez, “Orígenes de la Poesía Castellana,” Málaga, 1754, 4to, pp. 175. J. A. Dieze, who was a Professor at Göttingen, and died in 1785, published a German translation of it in 1769, with copious and excellent notes, which more than double, not only the size of the original work, but its value. The Life of Velazquez, who was Marquis of Valdeflores, though he does not generally allude to his title in his printed works, is to be found in Sempere y Guarinos, Bib., Tom. VI. p. 139. Mayans, a Valencian gentleman of learning, and another of those who had a considerable influence on Spanish literature at this period, followed a similar course in his “Retórica,” which appeared in 1757, and is founded rather on the philosophical opinions of the Roman rhetoricians than on the modification of those opinions by Boileau and his followers. It is a long and very cumbrous work, less fitted to the wants of the times than that of Luzan, and even more opposed to the old Castilian spirit, which submitted so unwillingly to rules of any sort. But it is a storehouse of curious extracts from authors belonging to the best period of Spanish literature, almost always selected with good judgment, if not always skilfully applied to the matter under discussion.[318] [318] Gregorio Mayans y Siscar, who wrote and edited a great many books in Latin and Spanish, was born in 1699, and died in 1782. His life and a list of his works may be made out from the united accounts of Ximeno, Tom. II. p. 324, and Fuster, Tom. II. p. 98.
