According to Britannica, Vega Garcilaso had become acquainted with the poet Juan Boscán Almogáver, who quickly introduced him to Italianate metres, to the use of which he was further attracted by his close study of such Italian Renaissance poets as Petrarch, Giovanni Boccaccio, and Jacopo Sannazzaro. Garcilaso was a consummate craftsman, and he transformed the Italianate metres into Spanish verse of high lyric quality. His most important innovations in this regard were the verse stanzas of the silva and liva (both using combinations of 7- and 11-syllable lines), which allowed him a new concern with the analytical expression of thought and emotion. Garcilaso’s major theme is the melancholy laments and misfortunes of romantic love as conventionally portrayed in pastoral poetry. He continually rewrote and polished his poetry, lifting his work high above that of his contemporaries and profoundly influencing the development of Spanish verse.
