The armorial of Mgr. Jules-Ernest Houssaye (Abbé Julio) (1844-1912), Primate of the Gallican Church (image courtesy Mission Gallicane d’Alsace):
He was admitted a member of the Order of the Crown of Thorns by Prince-Abbot Joseph III in 1893 and served as Prelate-Commander and its representative in France (later Switzerland) until his death, maintaining a Secretariat at 21 Croix-des-Petits-Champs, Paris. He was formally invested by Prince-Abbot Joseph III in 1898 at 5, Rue Vernier, Paris. His episcopal arms bear a suspension of the jewel of the Order and a photograph of his office shows his commander’s collar together with the sword of his commandery.
