Papal household in the context of "Gregory XI"

The camerlengo of the Holy Roman Church is an office of the papal household that administers the property and revenues of the Holy See. Formerly, his responsibilities included the fiscal administration of the Patrimony of Saint Peter. As regulated in the apostolic constitution Pastor bonus of 1988, the camerlengo is always a cardinal, though this was not the case prior to the 15th century. His heraldic arms are ornamented with two keys – one gold, one silver – in saltire, surmounted by an ombrellino, a canopy or umbrella of alternating red and yellow stripes. These also form part of the coat of arms of the Holy See during a papal interregnum (sede vacante). The camerlengo has been Kevin Farrell since his appointment by Pope Francis on 14 February 2019. The vice camerlengo has been Archbishop Ilson de Jesus Montanari since 1 May 2020.

The Second Council of Lyon was the fourteenth ecumenical council of the Roman Catholic Church, convoked on 31 March 1272 and convened in Lyon, Kingdom of Arles (in modern France), in 1274. Pope Gregory X presided over the council, called to act on a pledge by Byzantine emperor Michael VIII to reunite the Eastern church with the West. The council was attended by about 300 bishops, 60 abbots and more than a thousand prelates or their procurators, among whom were the representatives of the universities. Due to the great number of attendees, those who had come to Lyon without being specifically summoned were given "leave to depart with the blessing of God" and of the Pope. Among others who attended the council were James I of Aragon, the ambassador of the Emperor Michael VIII Palaiologos with members of the Greek clergy and the ambassadors of Abaqa Khan of the Ilkhanate. Thomas Aquinas had been summoned to the council, but died en route at Fossanova Abbey. Bonaventure was present at the first four sessions but died at Lyon on 15 July 1274. As at the First Council of Lyon, Thomas Cantilupe was an English attendee and a papal chaplain.

In addition to Aragon, which James represented in person, representatives of the kings of Germany, England, Scotland, France, the Spains and Sicily were present, with procurators also representing the kingdoms of Norway, Sweden, Hungary, Bohemia, Poland, and the "realm of Dacia". In the procedures to be observed in the council, for the first time the nations appeared as represented elements in an ecclesiastical council, as they had already become represented in the governing of medieval universities. This innovation marks a stepping-stone towards the acknowledgment of coherent ideas of nationhood, which were in the process of creating the European nation-states.
