Isidore of Seville (Latin: Isidorus Hispalensis; c. 560 – 4 April 636) was a Hispano-Roman scholar, theologian and archbishop of Seville. He is widely regarded, in the words of the 19th-century historian Charles Forbes René de Montalembert, as "the last scholar of the ancient world".
At a time of disintegration of classical culture, aristocratic violence, and widespread illiteracy, Isidore was involved in the conversion of the Arian Visigothic kings to Catholicism, both assisting his brother Leander of Seville and continuing after Leander's death. He was influential in the inner circle of Sisebut, Visigothic king of Hispania. Like Leander, he played a prominent role in the Councils of Toledo and Seville.
His fame after his death was based on his Etymologiae, an etymological encyclopedia that assembled extracts of many books from classical antiquity that would otherwise have been lost. This work also helped to standardise the use of the full stop, comma and colon.
Since the Early Middle Ages, Isidore has sometimes been called Isidore the Younger or Isidore Junior (Latin: Isidorus iunior), because of the earlier history purportedly written by Isidore of Córdoba.
Isidore (Spanish pronunciation: [/isiðoɾe/] ee-see-DOH-reh) was born in Cartago Spartaria (now Cartagena, Spain), a former Carthaginian colony, to a notable family in Roman Hispania, of high social rank, His father was named Severianus and his mother Theodora. His parents were members of an influential family who were instrumental in the political-religious manoeuvring that converted the Visigothic kings from Arianism to Catholicism. The Catholic and Orthodox Churches celebrate him and all his siblings as known saints:
An elder brother, Leander of Seville, immediately preceded Isidore as Archbishop of Seville and, while in office, opposed King Liuvigild.
A younger brother, Fulgentius of Cartagena, served as the Bishop of Astigi at the start of the new reign of the Christian King Reccared.
His sister, Florentina of Cartagena, was a nun who allegedly ruled over forty convents and one thousand consecrated religious. This claim seems unlikely, however, given the few functioning monastic institutions in Spania during her lifetime.
Isidore received his elementary education in the Cathedral school of Seville. In this institution, the first of its kind in Spania, a body of learned men including Archbishop Leander of Seville taught the trivium and quadrivium, the classic liberal arts. Isidore applied himself to study diligently enough that he quickly mastered classical Latin, and acquired some Greek and Hebrew.
Two centuries of Gothic control of Iberia incrementally suppressed the ancient institutions, classical learning, and manners of the Roman Empire. The associated culture entered a period of long-term decline. The ruling Visigoths nevertheless showed some respect for the outward trappings of Roman culture. Arianism meanwhile took deep root among the Visigoths as the form of Christianity that they received.
Scholars may debate whether Isidore ever personally embraced monastic life or affiliated with any religious order, but he undoubtedly esteemed the monks highly.
After the death of Leander of Seville on 13 March 600 or 601, Isidore succeeded to the See of Seville. On his elevation to the episcopate, he immediately constituted himself as the protector of monks.
Recognising that the spiritual and material welfare of the people of his see depended on the assimilation of remnant Roman and ruling barbarian cultures, Isidore attempted to weld the peoples and subcultures of the Visigothic kingdom into a united nation. He used all available religious resources toward this end and succeeded. Isidore practically eradicated the heresy of Arianism and completely stifled the new heresy of Acephali at its outset. Archbishop Isidore strengthened religious discipline throughout his see.
Archbishop Isidore also used resources of education to counteract increasingly influential Gothic barbarism throughout his episcopal jurisdiction. His quickening spirit animated the educational movement centred on Seville. Isidore introduced his countrymen to Aristotle long before the Arabs studied Greek philosophy extensively.
In 619 Isidore of Seville pronounced anathema against any ecclesiastic who in any way should molest the monasteries.
Second Synod of Seville (November 619)
Isidore presided over the Second Council of Seville, begun on 13 November 619 in the reign of King Sisebut, a provincial council attended by eight other bishops, all from the ecclesiastical province of Baetica in southern Spain. The Acts of the Council fully set forth the nature of Christ, countering the conceptions of Gregory, a Syrian representing the heretical Acephali.
Based on a few surviving canons found in the Pseudo-Isidorian Decretals, Isidore is known to have presided over an additional provincial council around 624.
