The episcopal arms of Prince-Abbot Joseph III (Mgr. Joseph-René Vilatte, 1854-1929) in a modern realization prepared for the Abbey-Principality by Mgr. Willy Fiorucci, OA. These are the arms conceded to Mgr. Vilatte at the time of his episcopal consecration by the Western Rite jurisdiction of the Syrian Orthodox Church in 1892. He had received the Grand Mastership of the Order of the Crown of Thorns of the 1891 foundation and the decoration of the Order is shown pendant from the shield in the arms.
