ARÉVALO, FAUSTINO. - Spanish Jesuit and patrologist, born at Campanario (Estremadura) in 1747, entered the Society of Jesus in 1761. He was one of the most notable among that group of learned religious who came to Italy after Charles III expelled the Society from Spain.
He became well known through his *Hymnodia hispanica, ad cantus latinitatis metrique leges revocata* (Rome 1786). He served as censor of the Academy of Catholic Religion, papal hymnographer (1800), and theologian of the Penitentiary (1800 and 1809–15). The favor of Cardinal Lorenzana enabled him to publish magnificent editions, based on Vatican manuscripts, of the poems of Prudentius (2 vols., Rome 1788–89), Dracontius (ibid. 1791), Sedulius (ibid. 1794), and other 4th-century poets; these editions were reproduced in Migne’s *Patrologia* (19 and 59–60). But the name of the author remains linked to his great, and still the best complete, edition of St. Isidore of Seville: *S. Isidori Hispalensis... opera omnia* (7 vols., Rome 1797–1803, reproduced in Migne, 81–84), followed by the *Missale gothicum secundum regulam b. Isidori Hispalensis* (Rome 1804). After the Society of Jesus was restored in 1814, he returned to Spain (1815) and died in Madrid on 7 January 1824. He left many unpublished works (listed in Uriarte-Lecina).
