Task: Question Answering
Input (English): Passage: From the age of six and for the rest of his life Saint-Saëns composed mélodies, writing more than 140. He regarded his songs as thoroughly and typically French, denying any influence from Schubert or other German composers of Lieder. Unlike his protégé Fauré, or his rival Massenet, he was not drawn to the song cycle, writing only two during his long career – Mélodies persanes ("Persian Songs", 1870) and Le Cendre rouge ("The Red Ash Tree", 1914, dedicated to Fauré). The poet whose works he set most often was Victor Hugo; others included Alphonse de Lamartine, Pierre Corneille, Amable Tastu, and, in eight songs, Saint-Saëns himself: among his many non-musical talents he was an amateur poet. He was highly sensitive to word setting, and told the young composer Lili Boulanger that to write songs effectively musical talent was not enough: "you must study the French language in depth; it is indispensable." Most of the mélodies are written for piano accompaniment, but a few, including "Le lever du soleil sur le Nil" ("Sunrise over the Nile", 1898) and "Hymne à la paix" ("Hymn to Peace", 1919), are for voice and orchestra. His settings, and chosen verses, are generally traditional in form, contrasting with the free verse and less structured forms of a later generation of French composers, including Debussy.Saint-Saëns composed more than sixty sacred vocal works, ranging from motets to masses and oratorios. Among the larger-scale compositions are the Requiem (1878) and the oratorios Le déluge (1875) and The Promised Land (1913) with an English text by Herman Klein. He was proud of his connection with British choirs, commenting, "One likes to be appreciated in the home, par excellence, of oratorio." He wrote a smaller number of secular choral works, some for unaccompanied choir, some with piano accompaniment and some with full orchestra. In his choral works, Saint-Saëns drew heavily on tradition, feeling that his models should be Handel, Mendelssohn and other earlier masters of the genre. In Klein's view, this approach was old-fashioned, and the familiarity of Saint-Saëns's treatment of the oratorio form impeded his success in it. 
Question: What were the full names of poets whose works Saint-Saëns set often from?
Output (English): Pierre Corneille.
