Isidore of Seville

Feast Day

April 4

Short Bio

As bishop in Spain during the twilight of the Roman empire, Isidore championed education and literacy among religious and laity alike. His focus was to weld a new nation from the various peoples of the Hispano-Gothic kingdom. He enforced religious discipline and clarity of religious understanding, rooted out Arianism and heresy, and presided over multiple Church councils. As the ‘Last Christian Philosopher’, he is the first Christian to have started an encyclopedia to preserve the best of past and present. He is credited with having saved a nation from illiteracy and barbarism.

Family Members

Parents: Severianus and Theodora

An elder brother, Saint Leander of Seville, immediately preceded Saint Isidore as Archbishop of Seville and, while in office, opposed king Liuvigild.

A younger brother, Saint Fulgentius of Cartagena, served as the Bishop of Astigi at the start of the new reign of the Catholic King Reccared.

His sister, Saint Florentina, served God as a nun and allegedly ruled over forty convents and one thousand consecrated religious. This claim seems unlikely; however, given the few functioning monastic institutions in Iberia during her lifetime, the claim could be creditable
