¹ The best modern summary is Howard Kaminsky, ‘The Great Schism’, in Michael Jones (ed.), The new Cambridge medieval history, Cambridge 2001, vi. 674–96. Noël Valois, La France et le grand schisme d'occident, Paris 1896–1902, repr. Hildesheim 1967, is the most detailed account of the events of 1378, with extensive transcriptions of contemporary testimony. Louis Gayet made greater use of the Libri de schismate (ASV, Armarium liv), but with some imperfect editions, in Le Grand Schisme d'occident d'après les documents déposées aux Archives secrètes du Vatican, Florence–Berlin 1889. Walter Brandmüller, Papst und Konzil im grossen Schisma (1378–1431): Studien und Quellen, Paderborn 1990, brings the bibliography closer to date and offers previously unused contemporary witnesses.

³ Bernard Guillemain, ‘Sur l'Efficacité de l'administration pontificale au xive siècle’, in Werner Paravicini and Karl Ferdinand Werner (eds), Histoire comparée de l'administration, Munich 1980, 143–8. Useful insights are provided by some of the studies in Aux Origines de l'état moderne: le fonctionnement administratif de la papauté d'Avignon, Rome 1990: see especially the lapidary essay by Jean Favier, ‘Traits généraux et traits spécifiques de l'administration pontificale’, 1–4, and also Kaminsky, ‘The Great Schism’, 678–80.

⁴ Noël Valois wrote a full objective history of the first election over a century ago: ‘L'Élection d'Urbain VI et les origines du grand schisme d'occident’, Revue des questions historiques xlviii (1890), 353–420, a painstaking reconstruction of the events from March to September 1378. Similarly candid and detailed, with an illuminating biographical investigation of Bartolomeo Prignano, is Olderico Přerovský, L'elezione di Urbano VI e l'insorgere dello schisma d'occidente, Rome 1960.

⁷ Přerovský, L'elezione, 1–31, provides the early biographical details. The pope's nephew, Cardinal Rinaldo Brancaccio, founded the church of Sant'Angelo a Nilo as a family chapel just south-east of San Domenico Maggiore.

⁸ For comparison, Prignano's later archbishopric of Bari was taxed at 600 florins, while Pierre de Cros's Arles was worth 2,000 florins: Conrad Eubel, Hierarchia catholica medii aevi, 2nd edn, Münster 1913, i. 70, 103, 128f.

¹⁴ For instance, the Rota or Audience of the Apostolic Palace was a court much occupied with suits claiming benefices and other ecclesiastical properties and rights, but the court of the chamberlain in Treasury Chamber was given superior standing to the Rota, and busied itself with collecting the taxes due for all ecclesiastical appointments, whoever won them: Daniel Williman, ‘Summary justice in the Avignonese Camera’, in Stephan Kuttner (ed.), Proceedings of the Sixth International Congress of Medieval Canon Law (Monumenta Iuris Canonici, Series C: Subsidia vii, 1985), 443–5.

¹⁹ I am indebted to Patrick Zutshi for notice of two original letters of Gregory xi dated 5 July 1377 (Archives Départementales des Bouches-du-Rhone, Marseilles, 2 H 258, nos 95, 96): ‘I find the initial R in the place where the vice chancellor or regens signs. I don't know who this R is, but clearly he is not Prignano.’ R was the usual signature of Jean Rousset, notary and registrar of the Camera, ‘l'un des hommes les plus actifs de l'entourage du camérier au temps du séjour à Anagni et Fondi’: Jean Favier, Les Finances pontificale à l'époque du grand schisme d'occident, 1378–1409, Paris 1966, 137. In the Curia of Clement vii at Avignon, papal bulls de curia were reviewed and endorsed by the chamberlain, and no longer by the vice-chancellor: Roger Ch. Logoz, Clément VII (Robert de Genève): sa chancellerie et le clergé romand au début du grand schisme (1378–1394), Lausanne 1974, 221.

²⁰ See Paul Maria Baumgarten, Von der apostolischen Kanzlei, Cologne 1908, 108–9, for mention of Prignano as vices gerens on 13 February 1377. By the pope's orders, benefices which had been requested before 13 September 1376 were to be granted by letters dated as from Avignon on that date, while the first date of letters from Rome should be Rome, St Peter's, 15 March 1377: Emil von Ottenthal (ed.), Regulae Cancellariae apostolicae: die päpstlichen Kanzleiregeln von Johannes XXII bis Nicolaus V, Innsbruck 1888, repr. Aalen 1968, 43–4, rules at pp. 86–91. The appointment of papal chaplains of honour was to become an important source of revenue for Pope Urban vi, but under his predecessors at Avignon the gifts paid in gratitude by new honorary chaplains were quite unofficial and unrecorded.

³⁷ Salvatore Fodale, La politica napoletana di Urbano VI, Rome 1973, 20–1 (texts in nn. 25–8). See also ‘I dispacci’, xliv. 271.

But there was no schism at that point, no rival pope, and those were the cardinals named by Urban as chief rebels. Giovanna's choice in July was really between adhering to an election which had become doubtful and attending to the formal written warnings of the cardinals as a college, and of Pierre de Cros. The fact that Urban had gratuitously insulted her representatives very likely inclined her toward the latter choice.

⁴⁴ De Cros, testimony, items 1, 2; Marc Dykmans, ‘La Bulle de Grégoire xi à la veille du Grand Schisme’, Mélanges: antiquité, moyen âge lxxxix (1977), 485–95. No original exists, and the bull is known only from later copies and an awkwardly registered version, ASV, Registra Avinionensia 204, fo. 9r, labelled ‘de Camera sine signo’. Dykmans judged that de Cros concealed the bull from the cardinals, but his evidence also permits the conclusion that the constitution was a simple forgery by de Cros. Either way, the chamberlain used his access to papal power furtively.

⁴⁵ The castellan's uncle, captain of the garrison, told of the oath in a letter to the king of Castile, BNF, ms lat. 11745, fo. 64v. The bishop of Cordoba, an eyewitness, declared that the Breton officers flew Urban vi's eagle banner over the Castel until the new pope ordered Rostaing to hand it over to a new, Neapolitan, castellan, which Rostaing refused to do until he was paid a very large indemnity for his wages and his repairs to the Castel (ibid. fo. 136r). Both texts are edited in Étienne Baluze, Vitae paparum avenionensium, ed. Guillaume Mollat, Paris 1922, ii. 729. Urban vi finally wrote to the cardinals at Avignon on 15 June 1378, calling the story of the oath false but nevertheless asking them to write the required release: the pope's original letter close is ASV, Instrumenta miscellanea 2991.
