Captioned 'Episcopat' this composition mostly shows members of the French episcopacy grouped around the Pope, although the presence of Cardinal Antonelli and one English bishop - Audrey George Spencer, the Bishop of Jamaica - somewhat mars the logic of the arrangement. It's also stretching it a bit to class Monsignor Chigi (the Papal Nuncio) as a member of the episcopacy.
The larger medallion at the bottom of the composition contains a portrait of Monsignor Dupanloup, the Bishop of Orléans, surrounded by some twenty-six members of the teaching staff of the seminary of la Chapelle de St Mesmin.
