Archbishop of the most prominent Iberian city of his age for over three decades, he is regarded as 'the last scholar of the ancient world' and authored the renowned encyclopedia 'Etymologiae'.
Born around 560 in Cartagena, Isidore served as Archbishop of Seville from 600 or 601 until his death in 636. He is one of the most influential figures of the early Middle Ages, playing a crucial role in the intellectual and religious life of the Iberian Peninsula. He is best known for his monumental work, the *Etymologiae* (or *Origines*), a 20-book encyclopedia that attempted to compile all knowledge of his time, from grammar to theology, natural history, and the liberal arts. This work served as a major reference for centuries. He also presided over the Councils of Toledo IV (633) and Seville II (619), which consolidated Visigothic ecclesiastical orthodoxy and discipline. His vast erudition and influence on Western culture led him to be proclaimed a Doctor of the Church in 1722. He is considered the last of the Latin Fathers of the Church and the "last scholar of the ancient world."
