Dominic of Silos was an 11th-century Spanish Benedictine monk and theologian who served as the abbot of the Abbey of Santo Domingo de Silos. Born in Cañas, he initially worked as a shepherd before entering the monastery at San Millán de la Cogolla. After being expelled by the King of Navarre, he found sanctuary in Silos under the protection of King Ferdinand I. There, he transformed the decaying abbey into a flourishing center of scholarship, art, and spiritual reform, eventually becoming a recognized saint in the Catholic Church.
