Thus in the life of S. Benedict, that noble, calm, dignified, prudent, great-souled, and high-minded hero, there are recorded several occasions upon which he was confronted by extraordinary manifestations of evil spirits who resisted the building of his monastery upon the crest of Monte Cassino, where Satanism had been previously practised. It is not said that there were any visible appearances, save to S. Benedict alone,[52] but a succession of untoward accidents, of abnormal occurrences and constant alarms, plainly showed that the Saint was contending against superhuman difficulties. More than once he found it necessary to exorcize certain of his monks,[53] and so marked was his triumph over these malignant and destructive influences that he has always been venerated in the Church as a most potent “effugator dæmonum,” and is confidently invoked in the hour of spiritual peril and deadly attack. Great faith also is placed in the Medal of Saint Benedict. This medal, originally a cross, is dedicated to the devotion in honour of the Patriarch. One side bears the figure of the Saint holding a cross in his right hand, and the Holy Rule in his left. Upon the other is a cross together with the following letters arranged on and around it: C.S.P.B., Crux Sancti Patris Benedicti (The Cross of the holy Father Benedict). C.S.S.M.L., Crux Sacra Sit Mihi Lux (May the holy Cross be my Light). N.D.S.M.D., Non Draco Sit Mihi Dux (Let not the Devil be my guide). U.R.S.: N.S.M.U.: S.M.Q.L.: I.U.B.: Uade Retro Satana: Nunquam Suade Mihi Uana: Sunt Mala Quæ Libas: Ipse Uenena Bibas. (Begone, Satan, never suggest things to me, what thou offerest is evil, drink thou thyself thy poison).[54] The “Centenary” form of the medal (struck at Monte Cassino in 1880 to commemorate the 13th centenary of the birth of S. Benedict in 480) has under the figure the words: _Ex S.M. Cassino MDCCCLXXX_. Upon the same side round the edge runs the inscription: Eius in obitu n̅r̅o præsentia muniamur (May we be protected by his presence at the hour of our death), and the word PAX appears above the cross.
