Isidore

Isidore of Seville was born in Cartagena, in the late antique province of Carthaginensis in southeastern Hispania, in the mid-sixth century. Exact year of birth is not recorded in contemporary sources and is only estimated by later writers. His family was Hispano-Roman and of high standing. Later tradition names his father Severianus; three of his siblings are themselves venerated as saints: Leander, who preceded him as bishop of Seville and was a principal agent in the conversion of the Visigothic court from Arianism to Nicene Christianity; Fulgentius, bishop of Écija; and Florentina, who entered religious life. After the death of their parents the family was established at Seville, and Leander directed Isidore’s education in Scripture, Latin letters, and the ecclesiastical learning of the cathedral and monastic circles of Baetica.

Isidore succeeded Leander as bishop of Seville around the beginning of the seventh century and held the see until his death. As metropolitan of Baetica he was the foremost churchman of the Visigothic kingdom. He presided over the Second Synod of Seville in 619 and, more importantly, over the Fourth Council of Toledo in 633, which sought to unify liturgy, clerical discipline, and education across the realm and which required the maintenance of cathedral schools. He worked to consolidate the Catholic identity of the Visigoths after King Reccared’s conversion and to transmit classical and patristic knowledge to a clergy that no longer had ready access to the full libraries of late antiquity. He was a diocesan bishop, not a member of a later religious order, though he wrote a monastic rule and strongly promoted regular life.

His writings made him one of the chief intermediaries between the ancient and medieval Latin worlds. The Etymologiae (Origins), an encyclopedia in twenty books, gathered definitions and summaries of the arts, law, medicine, natural history, geography, and theology, often arranged around the supposed derivations of words; it was among the most widely copied books of the Middle Ages. He also composed a history of the Goths, Vandals, and Suevi; On the Nature of Things; On Ecclesiastical Offices; treatises on the Catholic faith; grammatical and moral works such as the Differentiae and Synonyma; and other exegetical and pastoral texts. He compiled rather than invented, drawing on Augustine, Jerome, Cassiodorus, and pagan encyclopedists, and recast them for the use of seventh-century Spain.

Isidore died in Seville on 4 April 636. Near-contemporary notices, including that of his disciple Braulio of Zaragoza, describe him as giving what remained of his goods to the poor and making a public confession before receiving the last sacraments. He was first buried in Seville. In the eleventh century his relics were translated to León, where they are kept in the Basilica of San Isidoro. His feast in the Roman calendar is 4 April. He was venerated as a saint from the early Middle Ages without a later-style papal canonization; in 1722 Pope Innocent XIII declared him a Doctor of the Church. In modern devotion he is invoked as patron of Seville and of students, and, by analogy with his encyclopedic labors, of computer users, programmers, technicians, and the Internet, a patronage popularized in the late twentieth century rather than conferred by a universal decree of the Holy See.
