O presente trabalho “Ecos de uma tradição: a ideia de decadência na obra Epitoma Rei Militaris, de Flavius Vegetius Renatus” analisa os escritos desse autor romano dos séculos IV-V d.C., cujo tratado pretendia servir como base para uma reforma no exército imperial. Procuro compreender o funcionamento da ideia de decadência em sua obra, partindo da noção de formação discursiva, desenvolvida por Michel Foucault. A partir dessa problemática, os enunciados, objetos, estratégias e conceitos que compõem e constroem o discurso da decadência são descritos. Na medida em que são analisados os autores fontes de Vegetius, os enunciados são ligados a uma tradição decadentista. O objetivo final desta pesquisa é analisar o diálogo entre esta tradição e o uso dos enunciados na obra em questão. / This work entitled “Echoes of a tradition: the idea of decadence in the work Epitoma Rei Militaris, of Flavius Vegetius Renatus” examines the writings of the said roman author of the fourth-fifth century A.D., whose treaty was intended to serve as the basis for a reform of the imperial army. I try to understand the operation of the idea of decadence in his work, based on the notion of discursive formation, developed by Michel Foucault. Based on this problematic, the statements, objects, strategies and concepts that compose and construct the discourse of decline are described. Throughout the analyzes of Vegetius and its sources the statements are linked to a decadent tradition. This research’s goal is to exam the dialogue between this tradition and the use of statements in the book in question.

En tant que colonie romaine, capitale administrative de la province de Lyonnaise, la ville de Lugdunum tisse depuis ses origines des liens étroits avec l’exercitus romanus. Impliquée directement, et à plusieurs reprises, dans des conflits militaires de grande ampleur, elle est la seule ville de Gaule à avoir accueilli une cohorte urbaine, dont l’existence est attestée par les sources écrites comme par les inscriptions funéraires. Face à ces témoignages, et à défaut de découvertes récentes, l’archéologie, jusqu’ici peu prise en compte, apparaît comme une source complémentaire de poids pour comprendre les modalités de la présence et de l’occupation militaire de Lugdunum. Le développement récent de l’archéologie programmée et préventive a favorisé la collecte d’un mobilier toujours plus abondant. Parmi les ensembles d’instrumentum recueillis, certains objets, appelés militaria, relèvent de la sphère militaire. Le travail exposé au sein de cette thèse se propose donc de traiter de la question de la présence militaire romaine à Lugdunum à travers le prisme de ces artefacts archéologiques. L’étude proposée s’appuie sur un corpus de de 496 fragments pour 337 objets, répartis sur quarante sites disséminés sur le territoire de la colonie romaine et ses abords proches. Chaque artefact fait l’objet d’une étude exhaustive selon les catégories fonctionnelles en usage (armement offensif et défensif, ceintures/baudrier, harnachement, autres). Une discussion d’ordre technologique, typologique et chronologique est proposée pour chacun d’eux, sur la base des comparaisons observées à l’échelle du monde romain. A l’appui des données collectées, une discussion d’ordre quantitative, spatiale et contextuelle est engagée ainsi qu’une réflexion sur une éventuelle production artisanale de certaines catégories d’armement et d’équipement militaire à Lugdunum. Les résultats de l’étude servent de point d’appui pour un discours élargi sur la présence militaire romaine à Lyon entre le Ier et le IVe s. apr. J.-C. La confrontation des données archéologiques, historiques et épigraphiques permet de proposer plusieurs hypothèses sur la nature de l’occupation militaire de Lugdunum, sur son évolution et sa densité mais aussi son intégration au tissu urbain de la colonie de droit romain. / As a roman colony and administrative capital of the Gaul Lyonnaise province, the city of Lugdunum entwines, since its origins, direct links with the exercitus romanus. This city was entangled directly and often in major military conflicts. Furthermore, it was the only settlement in Gaul to welcome a roman cohort, whose existence is confirmed by written sources such as funerary inscriptions. Taking into account these evidences, and lacking of recent findings, Archeology, lightly valued till now, appears as a great important source to understand the procedures of the military presence and occupation in Lugdunum. Recentdevelopments in both rescue and voluntary Archeology, favored the assemblage of a great number of collections. Among the gathered sets of instrumentum, certain objects arise mainly from the military sphere, the militaria.The work set out at the center of this thesis enables to approach the interpretation of the roman military presence in Lugdunum through the perspective of these archeological artifacts. The present study relies on a militaria corpus of 496 fragments to 337 objects, diffused over forty sites, scattered on the territory of the roman colony and its outskirts. Each artifact wassubjected to a thorough research, according to the classifications in use: defensive and offensive armament, belts, straps, harness and others. A technological, typological and chronological analysis is proposed for each one of them, based on the fieldwork observed at the scale of the roman world. After analyzing the data collected, conclusions about space, context and quantity can be established, as well as the notion of a possible craft-related production of certain types of military weaponry and equipment in Lugdunum.The results of this study provide a support for a broader discussion, as it concerns the roman military occupation in Lyon between the 1st century BC and the 4th century AD. The combination of the archaeological, historical and epigraphical data allows several hypothesis on the nature of the military establishment in Lugdunum, but also on its evolution, density andits role on the urban network of the colony of roman law.

Диссертация посвящена эволюции военно-административной системы Римской империи в восточных провинциях в I в. н. э. Состояние источников позволяет утверждать, что регион Ближнего Востока наиболее репрезентативен для изучения данной проблемы. В I в. н. э. Рим начал переход от завоевательной стратегии к обороне границ. Одновременно с этим, провинции стали играть важную роль во всех сферах жизни Римского государства. Эти процессы обусловили значительные преобразования в римской армии. Автором установлено, что особенности римской военной системы на Востоке империи – дислокация армейских контингентов, организация обороны границ, снабжение и комплектование воинских подразделений – зависели от внешнеполитической ситуации и комплекса внутриполитических причин. / The dissertation is devoted to evolution of the Roman military-administrative system in the Eastern provinces of the Empire in the first century A. D. During the studied period, Rome was beginning transition from offensive wars to defense of the frontiers. In the same time, the provinces of the Empire began to play a greater role in the state. These processes contributed to transformation of the Roman armed forces, which were evolutionary character. Roman foreign policy activity in the Near East allows suggesting, that this region is the most representative for research of evolution of the Roman military organization in the first century A. D. The author ascertained that special aspects of the Roman military machine in the Eastern provinces of the Empire (dislocation of the armed forces, organization of defense of the frontiers, supply and recruitment of various military units) depended on foreign policy situation and complex of internal political reasons.

L’armée de Gaule sous le Bas-Empire fut une des trois armées principales de l’Empire romain. Son évolution de la fin du IIIe siècle jusqu’au début du Ve fut marquée par une réorganisation graduelle dans le commandement, ainsi que dans l’organisation des troupes et des fortifications. Ces réformes ont fait l’objet d’études qui ont dressé un schéma de déploiement des troupes resté longtemps populaire. À ce schéma s’est ensuite ajoutée l’idée de la stratégie à grande échelle qui y aurait été associée. Ce mémoire tâche de dresser une synthèse des derniers travaux sur l’armée romaine tardive en Gaule. L’approche choisie repose sur une réévaluation des sources sans l’influence d’un schéma défensif préconçu, ainsi que sur une critique de certaines idées reçues concernant l’armée romaine du IVe siècle. / The army stationed in Gaul during the Later Empire was one of the three main armies available to the Roman Empire. Its evolution from the late IIIrd century to the early Vth century was marked by reforms applied gradually to the high command, and to the organization of troops and fortifications. These measures have interested scholars who established a model of troop deployment which enjoyed great popularity over a long period of time. The idea of strategy applied on a great scale was later included in this concept. This thesis proposes a synthesis of the latest research on the late Roman army in Gaul. The selected approach of analysis is based on a reevaluation of the sources without the bias of a preconceived defensive model. Some obsolete ideas regarding the late Roman army will also be subject to criticism.

Cette thèse a pour objet de mener une réflexion sur les différentes fonctions entre la frontière de Germanie supérieure et celle de Germanie, en insistant plus particulièrement sur sa dimension militaire et sa place dans la stratégie de défense de l’Empire. L’étude de ce limes est particulièrement intéressante des Sévères à Dioclétien, car c’est une période où il connaît de nombreuses transformations et adaptations jusqu’à son abandon et le retour sur la 'ripa ' du Rhin. Après avoir défini le limes et ses fonctions, nous verrons que les échanges y sont limités entre le monde romain et germanique et qu’il est efficace pour lutter contre les raids de faible intensité. Son abandon s’explique à la fois par les guerres civiles et par les mutations dans le monde germanique. Après l’unité retrouvée de l’Empire, les empereurs créent une nouvelle ligne de défense sur le Rhin qui est complétée par la création d’un Etat-tampon, l’Alamannia. / This thesis aims to reflect on the different functions between the upper border of Germany and that of Germany, with particular emphasis on its military dimension and its place in the Empire defense strategy. The study of the limes is particularly interesting from the Severi to Diocletian, because this is a period when it has many changes and adjustments to its abandonment and the return on the 'ripa' the Rhine. After defining the limes and its function, we will see that trading is limited between the Roman and Germanic world and that effective against low-intensity raids. Its abandonment is explained both by civil wars and by changes in the Germanic world. After the rediscovered unity of the Empire, the emperors created a new line of defense on the Rhine which is complemented by the creation of a buffer state, the Alamannia.

L’étude a pour objet le combat de cavalerie dans le monde romain du Ier siècle a.C. au VIe siècle p.C. Il s’agit d’un travail de synthèse, traitant de la doctrine d’emploi de la cavalerie aux époques impériale et proto-byzantine. Les questions organisationnelles et stratégiques sont abordées, mais la focale est surtout mise sur la tactique et la physionomie du combat. L’objectif de cette recherche est de rendre compte de l’évolution de l’art de la guerre durant la fin de l’Antiquité en analysant spécifiquement les enjeux liés au développement et à l’utilisation de la cavalerie. L’importance croissante des troupes montées dans la stratégie impériale marque en effet une rupture importante dans l’histoire de l’armée romaine. Au primat des guerres offensives, de la bataille rangée et de l’infanterie lourde succède progressivement celui de la temporisation, de la guérilla frontalière et des cavaliers-archers. Ces changements, qui n’ont jamais fait l’objet d’une analyse approfondie, sont ici situés dans le temps long de l’Antiquité romaine. Le dialogue des sources narratives, techniques, figurées et archéologiques permet de dégager un schéma évolutif cohérent, un « développement organique des formes de combat » (Hans Delbrück) que nous nous efforçons de réinscrire dans le contexte plus large de l’évolution de la culture militaire impériale, en attachant une importance particulière au rapport des Romains à la guerre et à leur perception idéale des rôles respectifs de l’infanterie et de la cavalerie. / This study is about cavalry warfare in the Roman world from the 1st century BC to the 6th century AD. It is a work of synthesis dealing with the employment doctrine of cavalry in the imperial and early Byzantine eras. Organizational and strategic issues are discussed, but the focus is mainly put on tactics and battle mechanics. The aim of this research is to account for the evolution of the art of war during the end of Antiquity by analyzing specifically the stakes involved in the development and use of cavalry. The growing importance of mounted troops in the imperial strategy marks an important change in the history of the Roman army, with a gradual shift from offensive warfare, pitched battle and heavy infantry toward deception, frontier warfare and mounted archery. These changes, which have never been the subject of a thorough analysis, are here reviewed in the overall context of Roman history. The cross-analysis of narrative, technical, iconographic and archaeological sources reveals a coherent evolutionary pattern, an "organic development of forms of combat" (Hans Delbrück), which we endeavor to reinsert in the wider context of a changing Roman military culture, attaching particular importance to the Romans' relationship to warfare and to their ideal perception of the respective roles of infantry and cavalry.
