At the head of these authors must indisputably be named Fernando de Herrera, a man to whom poetic elocution owes more than to any other. His genius was equal to his industry; and, familiar with Latin, Greek, and Hebrew, he devoted himself to the imitation of the great writers of antiquity, to form a poetic language which might compete in pomp and wealth with that which they used in their verses. He was not, it is true, circumstanced like Juan de Mena; he had not the license to suppress syllables, syncopate phrases, or change terminations. This physical part of the language was now fixed by Garcilasso and his imitators, and could not suffer alteration. But the picturesque part might, and in fact, did receive from him great improvements: he made much use of the compound epithets that already existed, he introduced other new ones, he re-established many forgotten adjectives, to which he imparted new strength and freshness by the fitness with which he applied them, and used in fine more phrases and modes of speech distinct from usual and common language than any other poet. To this careful attention, he added another quality, not less essential, that of painting to the ear by means of imitative harmony, making the sounds bear analogy with the image. He breaks them; he suspends them; he drags them wearily along, he precipitates them at a stroke; he rubs them into roughness, he touches them into mildness;--in short, they sometimes roll fluently and easily along, at others they pierce the ear with a calm and quiet melody. These effects, which the verses of Herrera produce by the mechanism of their language, distinguish them from prose in such a manner, that though they may be broken up, and lose their measure and cadence, they still preserve the picturesque and poetic character which the poet stamped upon them.
