Isidore

Isidore of Seville (Latin: Isidorus Hispalensis) was archbishop of Seville in Visigothic Spain and one of the chief scholars of the early medieval Latin West. Traditional accounts, followed by most modern reference works, place his birth at Cartagena in the mid-sixth century, into a Hispano-Roman family of high standing. Later sources name his father Severianus; a mother called Theodora appears in some traditions. The household was unusual for the number of its members later venerated as saints: Isidore’s elder brother Leander became archbishop of Seville and a leading figure in the conversion of the Visigothic kings from Arianism to Nicene Christianity; another brother, Fulgentius, became bishop of Ecija (Astigi); their sister Florentina became an abbess. Byzantine occupation of parts of the southeastern coast and related political turmoil appear to have driven the family west to Seville, where Isidore was raised and given a thorough education in Latin letters, Scripture, and the surviving classical curriculum under Leander’s direction.

After Leander’s death Isidore succeeded him as archbishop of Seville, most probably at the turn of the seventh century, and he remained in that office until his own death more than three decades later. As metropolitan of Baetica he worked to consolidate Catholic orthodoxy among the Visigoths, to raise the educational standard of the clergy, and to regulate monastic and diocesan life. He took a leading part in the Second Council of Seville in 619 and presided over the Fourth Council of Toledo in 633, whose canons dealt with liturgy, clerical discipline, schooling, and the legal position of Jews, and which sought greater uniformity across the Visigothic kingdom. He also composed a monastic rule and encouraged the foundation and reform of monasteries. In a period when much ancient learning survived only in fragments, he made it his task to gather, arrange, and transmit that inheritance for the use of the Church.

Isidore’s reputation rests above all on his writings. The work for which he is best known is the Etymologiae (also called Origines), an encyclopedic compilation in twenty books covering grammar, rhetoric, mathematics, medicine, law, theology, animals, geography, building, and many other subjects, often organized through the supposed origins of words. He further wrote a history of the Goths, Vandals, and Suebi (Historia de regibus Gothorum, Vandalorum et Suevorum); the cosmological handbook De natura rerum; De ecclesiasticis officiis on church offices and worship; the moral-theological Sententiae; and biblical and linguistic studies including Differentiae and Quaestiones in Vetus Testamentum. Medieval libraries copied the Etymologiae on a very large scale; it became a standard reference for centuries and a principal conduit of ancient learning into the Carolingian world and the later Middle Ages.

Isidore died in Seville on 4 April 636 and was first buried in that city. In 1063 King Ferdinand I of León had his relics translated to León, where they remain in the Basilica of San Isidoro. Veneration of him as a saint began in the early Middle Ages and spread with both Mozarabic and Roman usage; there was no later papal canonization of the post-medieval type. In 1722 Pope Innocent XIII declared him a Doctor of the Church. His feast is kept on 4 April. Because of the range of his encyclopedia he has in modern times been popularly invoked as patron of students and of the Internet and of computer users and technicians, an association promoted by Spanish church authorities in the late twentieth century even though it does not rest on a single well-known universal papal decree of patronage.
