(born circa 560, Cartagena or Sevilla, Spain—died April 4, 636, Sevilla; canonized 1598; feast day April 4) Spanish prelate and scholar, last of the Western Fathers of the Church. He became archbishop of Sevilla circa 600 and presided over several councils that shaped church policy, including the fourth Council of Toledo (633). He also promoted the conversion of the Visigoths from Arianism to orthodox Christianity. His best-known work was Etymologies, an encyclopedia that became a standard reference work in the Middle Ages. He also wrote theological works, biographies, and treatises on natural science, cosmology, and history. He was canonized in 1598 and declared a Doctor of the Church in 1722.

At a time of disintegration of classical culture, and aristocratic violence and illiteracy, he was involved in the conversion of the royal Visigothic Arians to Catholicism, both assisting his brother Leander of Seville, and continuing after his brother's death. Like Leander, he took a most prominent part in the Councils of Toledo and Seville. The Visigothic legislation which resulted from these councils is regarded by modern historians as exercising an important influence on the beginnings of representative government.
Isidore received his elementary education in the Cathedral school of Seville. In this institution, which was the first of its kind in Hispania, the trivium and quadrivium were taught by a body of learned men, among whom was the archbishop, Leander. With such diligence did he apply himself to study that in a remarkably short time mastered Latin, Greek, and Hebrew.
Whether Isidore ever embraced monastic life or not is still an open question, but though he himself may never have been affiliated with any of the religious orders, he esteemed them highly — on his elevation to the episcopate he immediately constituted himself protector of the monks and in 619 he pronounced anathema against any ecclesiastic who should in any way molest the monasteries.
After the death of Leander, Isidore succeeded to the See of Seville.
His long incumbency in this office was spent in a period of disintegration and transition. The ancient institutions and classic learning of the Roman Empire were fast disappearing. For almost two centuries the Goths had been in full control of Hispania, and their barbarous manners and contempt of learning threatened greatly to put back her progress in civilization.
Realizing that the spiritual as well as the material well-being of the nation depended on the full assimilation of the foreign elements, Isidore set himself to the task of welding into a homogeneous nation the various peoples who made up the Gothic kingdom. To this end he availed himself of all the resources of religion and education. His efforts were attended with complete success. Arianism, which had taken deep root among the Visigoths, was eradicated, and the new heresy of Acephales was completely stifled at the very outset; religious discipline was everywhere strengthened.
The council probably expressed with tolerable accuracy the mind and influence of Isidore. The position and deference granted to the king is remarkable. The Church is free and independent, yet bound in solemn allegiance to the acknowledged king: nothing was said of allegiance to the Bishop of Rome.
It was at the Fourth National Council of Toledo and through his influence that a decree was promulgated commanding and requiring all bishops to establish seminaries in their Cathedral Cities, along the lines of the school associated with Isidore already existing at Seville. Within his own jurisdiction he had availed himself of the resources of education to counteract the growing influence of Gothic barbarism. His was the quickening spirit that animated the educational movement of which Seville was the centre. The study of Greek and Hebrew, as well as the liberal arts, was prescribed. Interest in law and medicine was also encouraged. Through the authority of the fourth council this policy of education was made obligatory upon all the bishops of the kingdom.
The fame of this work imparted a new impetus to encyclopedic writing, which bore abundant fruit in the subsequent centuries of the Middle Ages. It was the most popular compendium in medieval libraries. It was printed in at least 10 editions between 1470 and 1530, showing Isidore's continued popularity in the Renaissance. Until the twelfth century brought translations from Arabic sources, Isidore transmitted what western Europeans remembered of the works of Aristotle and other Greeks, although he understood only a limited amount of Greek. The Etymologiae was much copied, particularly into medieval bestiaries.
Isidore taught in the Etymologiae that the Earth was round. His meaning was ambiguous and some writers think he referred to a disc-shaped Earth; his other writings make it clear, however, that he considered the Earth to be globular. He also admitted the possibility of people dwelling at the antipodes, considering them as legendary and noting that there was no evidence for their existence. Isidore's disc-shaped analogy continued to be used through the Middle Ages by authors clearly favouring a spherical Earth, e.g. the 9th century bishop Rabanus Maurus who compared the habitable part of the northern hemisphere (Aristotle's northern temperate clime) with a wheel, imagined as a slice of the whole sphere. See also: Flat Earth.
Isidore was the last of the ancient Christian philosophers, as he was the last of the great Latin Church Fathers. Some consider him to be the most learned man of his age, and he exercised a far-reaching and immeasurable influence on the educational life of the Middle Ages. His contemporary and friend, Braulio, Bishop of Saragossa, regarded him as a man raised up by God to save the Iberian peoples from the tidal wave of barbarism that threatened to inundate the ancient civilization of Hispania. The Eighth Council of Toledo (653) recorded its admiration of his character in these glowing terms: "The extraordinary doctor, the latest ornament of the Catholic Church, the most learned man of the latter ages, always to be named with reverence, Isidore". This tribute was endorsed by the Fifteenth Council of Toledo, held in 688.
