While the development of hagiography over time has long attracted the attention of medievalists, scholars have not fully explored the critical role of the liturgy in prompting and transmitting these changes. This dissertation examines the liturgies for the patron saints of three musical and ecclesiastical centers in medieval Aquitaine: the cathedrals of Saint-Trophime in Arles, Saint-Just-et-Saint-Pasteur in Narbonne, and Saint-Étienne in Toulouse. Through the music, texts, and ritual actions of the liturgy, the clerical communities of these three institutions reinforced some aspects of their patron saint's legendary biography and modified others. Yet the process unfolded differently at each cathedral, revealing the particular preferences of the canons of each community as well as their changing circumstances during the Middle Ages. In Arles, the office for St. Trophime, which was likely composed at the cathedral, shows dramatic changes in the saint's hagiography. The clerics in Narbonne also composed an office for their patron saints but did not substantially change the details of Justus and Pastor's legendary biography. In Toulouse, the canons selected from among the preexisting repertoire of chants and texts available for St. Stephen, crafting liturgies that were particular to Saint-Étienne within a clearly Aquitanian context. By revealing the ways in which the clerics of Saint-Trophime, Saint-Just, and Saint-Étienne shaped the legendary biographies of their patron saints, my work provides new insights into the ways in which clerical communities throughout Latin Christendom shaped and reshaped the hagiographic portraits of their patron saints through the creation, compilation, and celebration of new liturgies.

[pt] Mais de duzentos anos se passaram desde o início da Revolução francesa, será que já se falou demais sobre ela? Creio que não. Por ser um dos eventos fundantes das sociedades modernas, sua história é continuamente disputada. A sua complexidade vai além da simples categoria de revolução burguesa e autoriza ver neste evento um verdadeiro laboratório de experiências, não modelos, já que não se prestam a serem imitados, mas podem inspirar o presente para imaginar – e construir – o futuro. Assim, o presente trabalho se debruça sobre um período específico da Revolução francesa: o julgamento de Luís XVI; nesta cena, um personagem é principal, não Luís, mas o jovem revolucionário Saint-Just. Sendo o mais jovem membro da Convenção nacional, sobe à tribuna da assembleia e afirma de maneira contundente: Para mim, não vejo meio-termo, este homem deve reinar ou morrer. Segundo Saint-Just, um rei é um inimigo, deve ser combatido e não julgado. Para explorar esse corte em meio aos debates de quem e como julgar Luís XVI, apresento o seguinte trajeto: na primeira parte, investigo a biografia desse jovem revolucionário, os caminhos de sua formação e obras anteriores a seu début na carreira parlamentar. Na segunda parte, traço um breve histórico dos acontecimentos que precipitaram o fim da monarquia constitucional na França, para em seguida mergulhar na cena principal, o julgamento de Luís XVI. Apresento as teses jurídicas em questão, pró e contra a acusação e condenação no ex-monarca, as questões constitucionais, e busco mostrar a radical ruptura introduzida pela fala de Saint-Just, tendo em conta suas obras teóricas que nos foram legadas como fragmentos o Da natureza, do estado civil e da cidadania ou Regras da independência de Governo e o Instituições Republicanas. / [en] More than two hundred years have passed since the beginning of the French Revolution, have we talked too much about it? I think not. As one of the founding events of modern societies, its history is continually disputed. Its complexity goes beyond the simple category of bourgeois revolution and allows to see in this event a real laboratory of experiments, not models, since they do not lend themselves to be imitated, but can inspire the present to imagine - and build - the future. Thus, the present work focuses on a specific period of the French Revolution: the trial of Louis XVI; in this scene, the main character is the young revolutionary Saint-Just. Being the youngest member of the National Convention, he stands in the tribune of the assembly, and he sharply states: For myself, I can see no mean, this man must reign or die. According to Saint-Just, a king is an ennemi that must be fought, not tried. To explore this cut amid the debates of who and how to judge Louis XVI, I present the following route. In the first part, I investigate the biography of this young revolutionary, the paths of his formation and works before the beginning of his parliamentary career. In the second part, I trace a brief history of the events that precipitate the end of the constitutional monarchy in France, and then dive into the main scene, the trial of Louis XVI. I present the legal theses in question, pro and against the accusation and conviction in the former king, the constitutional issues, and I seek to show the radical rupture introduced by the speech of Saint-Just, keeping an eyes in his works De la nature, de l état civil et de la cité ou les règles d indépendance du gouvernement and Institutions républicaines. / [fr] Plus de deux cents ans se sont écoulés depuis le début de la Révolution française, en a-t-on déjà trop parlé? Je crois que non. Étant l un des événements fondateurs des sociétés modernes, son histoire est continuellement contestée. Sa complexité va au-delà d une simple catégorie de révolution bourgeoise et autorise à voir dans cet événement un véritable laboratoire d expériences, non pas desmodèles, car ils ne se prêtent pas à être imités, mais ils peuvent inspirer le présentpour imaginer – et construire – l avenir. Ainsi, le présent travail se penche sur unepériode spécifique de la Révolution française : le jugement de Louis XVI; dans cette scène, un personnage est principal, non pas Louis, mais le jeune révolutionnaireSaint-Just. Étant le plus jeune membre de la Convention nationale, il monte à la tribune de l Assemblée et affirme de manière tranchante : Pour moi, je ne vois point de milieu, cet homme doit régner ou mourir. Selon Saint-Just un roi est un ennemi et doit être combattu et non pas jugé. Pour explorer cette coupe au milieu des débats de qui et comment juger Louis XVI, je présente le chemin suivant : dans la première partie, j étudie la biographie de ce jeune révolutionnaire, les voies de sa formation et les œuvres antérieures à son début dans la carrière parlementaire. Dans la deuxième partie, je trace un bref historique des événements qui précipitent la fin de la monarchie constitutionnelle en France, pour ensuite plonger dans la scène principale, le procès de Louis XVI. Je présente les thèses juridiques en question,pour et contre l accusation et la condamnation dans le ci-devant monarque, les questions constitutionnelles, et cherche à montrer la rupture radicale introduite par le discours de Saint-Just, en prenant compte de ses œuvres De la nature, de l état civil et de la cité ou les règles d indépendance du gouvernement et Institutions républicaines.
