The study of the baths landscape of Rome in the Antiquity(Ist century B.C.- Vth century A.D.) aims at filling certain gaps concerning the research on the minor baths in the capital of the Empire. The thesis followed essentially five main chapters: we beforehand defined a historic and social frame in our study by insisting on the relative problems at the origin of the Roman bath and in its distribution in italic peninsula. We then bent over the methodological problems met during the establishment of our corpus. To conceive in a concrete way the Roman bath landscape, we indeed established a database every evidence of which corresponds to a bath complex known by sources(archaeological, epigraphic and literary). This catalog was approached under descriptive shape on our third chapter. Our fourth axis concerns particularly the legislation relative to these balnea, the definition of their status and the identification of their owners. Finally, a typological and technical study of the baths of Rome showed itself necessary to end this study in a exhaustive way.
