Introduction
Fernando de Valdés Salas (1483-1568) was one of the most influential figures of 16th-century Spain. Born in the town of Salas into a noble family of modest means, his brilliant career led him to hold the highest ecclesiastical and civil positions of the era. Educated at the prestigious College of San Bartolomé in Salamanca, where he served as rector and professor of canon law, he soon entered the circle of Cardinal Cisneros. He was successively bishop of Elna, Ourense, Oviedo, León and Sigüenza, before becoming Archbishop of Seville in 1546. As president of the Royal Council of Castile and advisor to Charles I and Philip II, he participated in the most important decisions of the kingdom. In 1547, he was appointed Inquisitor General, a position he held for nearly twenty years. Beyond his controversial inquisitorial work, his legacy endures in the institutions he founded: the College of San Pelayo in Salamanca, the College of San Gregorio in Oviedo and, above all, the University of Oviedo, inaugurated forty years after his death. His remains rest in the magnificent alabaster mausoleum sculpted by Pompeo Leoni in the Collegiate Church of Santa María la Mayor in Salas.
