The monastery was in terrible shape, spiritually and materially, and St. Dominic set about to restore the monastery and to reform the lives of the monks. He preserved the Mozarbic Rite (one of the variants of the Latin Rite) at his monastery, and his monastery became one of the centers of the Mozarbic liturgy. His monastery also preserved the Visigothic script of ancient Spain and was a center of learning and liturgy in that part of Spain.
St. Dominic of Silos died on December 20,1073, about a century before the birth of his namesake, St. Dominic of Calaruega. Before the Spanish Revolution of 1931, it was customary for the abbot of Silos to bring the staff of St. Dominic of Silos to the Spanish royal palace whenever the queen was in labor and to leave it at her bedside until the birth of her child had taken place.
About 100 years after St. Dominic’s death, a young woman made a pilgrimage to his tomb. There St. Dominic of Silos appeared to her and assured her that she would bear another son. The woman was Joan of Aza, and the son she bore grew up to be the “other” St. Dominic—the one who founded the St. Dominicans. In recent times, great interest in St. Dominic of Silos has arisen since the literary treasures of the library of Silos have become known. The abbey had a profound influence on spirituality and learning in Spain. Today the monastery is an abbey of the Benedictine Congregation of Solesmes housing a library of ancient and rare manuscripts.
