Isidore of Seville

Life events

1. Born — 560

   Isidore was born in Cartago Spartaria (now Cartagena, Spain) to Severianus and Theodora, a high-ranking Hispano-Roman family whose members played a central role in the political and religious maneuvering that converted the Visigothic kings from Arianism to Catholicism.

2. Educated — 575

   Isidore received his elementary education at the Cathedral school of Seville — the first institution of its kind in Spania — where a body of learned men including his brother Archbishop Leander taught the trivium and quadrivium; he mastered classical Latin and acquired some Greek and Hebrew.

3. Consecrated — 600

   After the death of his brother Leander on 13 March 600 or 601, Isidore succeeded to the See of Seville; on elevation to the episcopate he immediately constituted himself protector of monks and set about welding the Hispano-Roman and Visigothic peoples into a united Christian nation.

4. Wrote

   Isidore compiled the Etymologiae (also known as Origines), the first Christian summa of universal knowledge — 448 chapters across 20 volumes — preserving fragments of classical learning that would otherwise have been lost; Braulio of Zaragoza described it as 'practically everything that it is necessary to know.'

5. Council — 619

   Isidore presided over the Second Council of Seville, begun on 13 November 619 in the reign of King Sisebut, a provincial council of nine bishops from the ecclesiastical province of Baetica that countered the Christological heresy of the Acephali as represented at the council by the Syrian Gregory.

6. Wrote — 624

   Isidore issued the longer edition of his Historia de regibus Gothorum, Vandalorum et Suevorum in 624, incorporating the Laus Spaniae and the Laus Gothorum — a history of the Gothic, Vandal, and Suebi kings that constitutes a major source for the Visigothic period.

7. Council — 633

   Isidore presided over the Fourth National Council of Toledo, begun on 5 December 633, which at his instigation commanded all bishops of the Visigothic kingdom to establish cathedral seminaries teaching Greek, Hebrew, and the liberal arts — the first mandated episcopal education policy in Iberia.

8. Died — 636

   Isidore died on 4 April 636 in Seville after more than 32 years as archbishop; interred in Seville, his tomb was a centre of veneration for the Mozarabs through the centuries of Arab rule, until Ferdinand I of León and Castile transferred his remains to the Basilica of San Isidoro in León in the mid-11th century.

Documented claims

• Until the 12th-century Arabic translations reached Western Europe, the Etymologiae was the primary channel through which western Europeans accessed Aristotle and other Greek authors; it appeared in at least ten printed editions between 1470 and 1530. (certain)
• Pope Innocent XIII proclaimed Isidore a Doctor of the Church in 1722; the Eighth Council of Toledo (653) had already called him 'the extraordinary doctor, the latest ornament of the Catholic Church, the most learned man of the latter ages.' (certain)
• All four children of Severianus and Theodora are venerated as saints: Leander (Archbishop of Seville), Fulgentius (Bishop of Astigi), Florentina (nun), and Isidore — a family entirely enrolled in the sanctoral calendar. (likely)
• In the mid-11th century Ferdinand I of León and Castile obtained Isidore's remains from Abbadid ruler Abbad II al-Mu'tadid of Seville as tribute and reinterred them in the Basilica of San Isidoro in León; some bones are today in the cathedral of Murcia. (likely)
• Book VIII of the Etymologiae documents pre-Christian religious and magical beliefs, making it one of the few surviving records of magical thought in early medieval Europe, preserved even as Isidore condemned the practices as superstition. (certain)
