St. Isidore of Seville
Patron of the internet, computer users, students, encyclopedists
Saint Isidore (c. 560–636), Archbishop of Seville, was the last of the great Latin Fathers and the encyclopedist of the early Middle Ages. His Etymologiae, a twenty-book compendium of all human knowledge — grammar, medicine, agriculture, theology, the trades — preserved a vast amount of classical learning for the West and remained a standard reference for almost a thousand years. He presided over the councils of Toledo that organized the liturgy and discipline of the Visigothic Church, and laid the foundations of the cathedral schools whose pupils would in time become the medieval universities. Innocent XIII proclaimed him a Doctor of the Church in 1722, and John Paul II proposed him in our own time as a patron of the Internet.
