Isidore

Saint Isidore of Seville was a Hispano-Roman scholar, theologian, and metropolitan archbishop whose life and writings stand at the boundary between late antiquity and the early Middle Ages. He was born in the mid-sixth century, traditionally at Cartagena in southeastern Hispania, into a prominent family that later produced several saints. His father Severianus belonged to the Hispano-Roman aristocracy of Cartagena; political disruption connected with the Byzantine foothold on the Mediterranean coast led the household to settle in Seville. Isidore’s elder brother Leander became Archbishop of Seville and a principal architect of the Visigothic conversion from Arianism to Nicene Christianity; another brother, Fulgentius, became Bishop of Écija; their sister Florentina entered religious life as an abbess. After the early death of his parents, Isidore was formed intellectually and spiritually under Leander’s care and received a rigorous education in the classical and Christian curriculum still available at Seville.

He succeeded Leander as Archbishop of Seville around the year 600 and held that see until his death. In office he worked to consolidate Catholic orthodoxy in the Visigothic kingdom, to raise the educational standard of the clergy, and to give the Spanish church a more uniform liturgical and disciplinary life. He took a leading part in the Second Synod of Seville in 619 and presided over the Fourth Council of Toledo in 633, which required the establishment of cathedral schools, insisted on clerical education, and promoted liturgical unity across the Iberian sees. His episcopate coincided with the reigns of several Visigothic kings, including Sisebut, to whom he dedicated a treatise on the natural world. He used metropolitan authority to encourage a learned pastoral clergy rather than a merely administrative hierarchy, and he is often described as completing, in institutional form, the Catholic settlement that Leander and King Reccared had begun at the Third Council of Toledo in 589.

Isidore’s lasting fame rests on his writings, which gathered and transmitted the learning of the ancient world for a new age. The encyclopedic Etymologiae, in twenty books, became one of the most widely copied Latin works of the Middle Ages and served as a principal vehicle by which fragments of classical grammar, rhetoric, mathematics, medicine, law, and natural history reached medieval readers. He also composed a chronicle of world history; a history of the Goths, Vandals, and Suevi; treatises on the nature of things, on ecclesiastical offices, and on differences of words and of things; and a collection of theological sentences. Later generations regarded him as the last of the Western Church Fathers. He died in Seville on 4 April 636.

His cult developed soon after his death. In the eleventh century his relics were translated from Seville to León, where they rest in the Basilica of San Isidoro. In 1598 Pope Clement VIII confirmed the ancient cult by inscribing him in the Roman Martyrology, and in 1722 Pope Innocent XIII declared him a Doctor of the Church. His feast is kept on 4 April. In 1997 Pope John Paul II named him patron of the Internet and of computer users, a modern recognition of his medieval reputation as a compiler and organizer of knowledge. He is also invoked as patron of students, of computer technicians and programmers, and of the city of Seville.
