The Benedictine Monks of Santo Domingo de Silos are based in the Silos Monastery located near Covarrubias in the south of Spain. The abbey was first established under the Rule of Saint Benedict in the year 954, and then re-founded by the monk Dominic in 1041, acting as its first abbot until his martyrdom in 1070. St. Dominic of Silos established a scriptorium at the abbey, and despite its being dispersed at one point, the library still holds some of the oldest sacred manuscripts in Europe -- some dating even to the ninth century. The famed Codex of the Monastery of Saint Domingo de Silos (British Library Add. Ms. 11695) is not a musical manuscript, but a Beatus prized for its extraordinary and elaborate miniatures.
