IN his apostolic letter Archicoenobium Casinense (1913), on the occasion of the consecration of a crypt chapel at the abbey of Monte Cassino decorated in the Beuronese style, Pope St. Pius X likened the artistic efforts of the Benedictines of Beuron to the revival of Gregorian chant by the Benedictines of Solesmes when he wrote, “...together with sacred music, it proves itself to be a powerful aid to the liturgy” (AAS5, 1913, pp.113-17).
