This dissertation offers a comparative study of two key figures of the Italian Renaissance, the ambassador and the courtesan, and the place of their bodies in relation to the Renaissance body politic. In studying myriad textual spaces of the body natural within writings by and about these two seemingly opposite figures, I find that these spaces range from the material to the metaphorical. In the Renaissance material spaces were increasingly allocated to both figures, urban confinement for the prostitute, and the establishment of the embassy for the ambassador. Metaphorically, the prostitute becomes the "body" of the state, while the ambassador personifies its "mind". My dissertation proves that by allocating such material and metaphorical spaces to these figures, the early modern state effectively denies them the possibility of ownership over their own bodies. This ownership, however, is rhetorically reclaimed, I argue, through the bodies of their own texts. / Romance Languages and Literatures

The main aim of this thesis is to introduce personality and works of imperial diplomat Franz Philip of Sternberg, who was appointed as imperial plenipotentiary at the court of Augustus III in 1749 and who spent there fifteen years. For those purposes, we are first presenting available literature concerning imperial diplomacy and diplomacy in Poland and Saxony in the 2nd half of the 18th century. Sources regarding other diplomats dwelling in Poland and Saxony by that times are also described. Next, we outlined historical sources available for the study of Sternbergs' diplomatic mission. Afterward, we introduced Franz Philip of Sternberg and his prepositions for his position as an imperial diplomat. Based on historical sources, we reconstructed Sternbergs' stay in Saxony and later in Poland, to where he resettled, altogether with Polish-Saxony royal court, after the reversal of longstanding alliances and the beginning of the Seven Years' War. For the reconstruction, we used mainly official diplomatic sources - instructions and relations, which are subsequently, together with diplomatic sources, subjected to diplomatic analysis. Based on unofficial correspondence, we have shown the social network of Franz Philip of Sternberg during his diplomatic stay in Poland and Saxony. In the end, we concluded on...

S’appuyant sur un corpus de textes que l’on qualifie normalement de « traités sur l’ambassadeur », cette thèse s’attache à reconstruire la naissance de la diplomatie moderne tout au long d’une période qui va du XIIIe au XVIIe siècle, en essayant d’analyser la manière dont la figure de l’ambassadeur à été élaborée à l’intérieur d’un champ de problématisation qui se caractérise par une imbrication réciproque du droit, de l’éthique et de la politique et va constituer une véritable expérience de la diplomatie.Ce travail s’articule en deux parties. Dans la première il s’agit de comprendre comment la figure de l’ambassadeur a été façonnée sous le profil de son statut juridique, à savoir comme une persona publica chargée d’un officium et devant représenter son mandant, avec les conséquences qui en découlent quant à l’établissement de son pouvoir de négociation, à la définition de ses immunités ainsi qu’à la détermination des honneurs qu’il a le droit de recevoir. L’analyse de ces questions permettra d’apprécier la contribution apportée par notre corpus non seulement à la définition du statut juridique de l’ambassadeur, mais aussi à la formation du nouveau droit des gens destiné à régir l’Europe moderne. La seconde partie s’attache à comprendre comment la figure de l’ambassadeur a été façonnée sous le profil de son statut professionnel : on s’interroge alors sur les fonctions qui lui sont attribuées, sur les moyens qui lui sont fournis et les conditions qui lui sont demandées pour s’en acquitter de la manière la plus efficace, ainsi que sur la problématisation éthique à laquelle son action est soumise. Tout en essayant de faire ressortir la spécificité de l’ambassadeur, cette partie se propose aussi de contribuer à l’étude de la professionnalisation du fonctionnaire public. / Using a collection of texts commonly known as the “treatises on the ambassador”, this research examines the birth and the development of the experience of diplomacy from the 13th to the 17th Century. It aims, in particular, to explore the development of the figure of the ambassador within a field of problematization involving ethics, politics and law.After some methodological and historical remarks, the thesis deals with the development of the status of the ambassador from two perspectives, the legal and the professional. Regarding his legal status, the medieval legal conceptualisation of the role of the ambassador as a genuine public “office”, and that of the diplomatic function as “representation”, are examined. The way in which these conceptualisations help to define the negotiating powers conferred on the ambassador, his immunities and the honours to which he is entitled is then considered. This analysis allows for an investigation of the complex links between the exercise of diplomacy and claims to sovereignty during Europe’s transition from the Middle Ages to Modernity. Regarding his professional status, the thesis reconstructs the functions of the ambassador (particularly in relation to information gathering and negotiation), the means provided for the ambassador to undertake his functions (his salary and the assignment of an escort) and the objective, intellectual or moral qualities required of him. As well as illustrating the techniques which have been required for ambassadorial success since the 15th Century, this analysis offers some hints for studying the professionalization of public officials and the emergence of the modern criteria of political analysis.
