Le culte de Liber Pater en Italie : identité divine et pratiques rituelles

This dissertation is structured in three distinct sections: in the first one, we examine the divine figure of Liber Pater and the perception of this divinity in Roman Italy. Liber never ceases to surprise scholars, mostly because of his association with Dionysus, so it is necessary to address a simple but crucial question: who is Liber Pater? We emphasize in this section that Liber is an agrarian deity recognized within the pantheon of Rome and thus receives a public cult through the Liberalia and the triad that he forms with Ceres and Libera. The tutelage of Liber on libertas is also questioned: rather than understanding it in terms of political freedom, we must rather focus on a physical and mental freedom. In the second section, we establish a connection on the Italian territory between Liber and Dionysus-Bacchus thanks to the process of acculturation that took place with the arrival of Dionysus in Magna Graecia in the 8th and 7th century BC. We then explore, through the tutelage of Liber and Bacchus over wine as well as the repression of the Bacchanalia, the heterogeneous forms that the rituals and cults dedicated to these deities may have taken. Finally, our last section dives into the cult of Liber in Italy in the Early Empire. To do so, we use the methodological framework of lived ancient religion, which focuses on the spectrum of religious strategies that can be put in place to communicate with Liber, be it through donation, prayer, gesture, sacrifice, etc. This model of analysis gives us the opportunity to focus on the lived worship of Liber, therefore bringing us closer to the religious experience of individuals. We demonstrate, through an epigraphic corpus comprising several types of inscriptions, that numerous communication strategies were used, notably the rituals of votum, dedicatio, and consecratio through the donation of objects such as altars and statues. In groups, these strategies become more complex since the associative phenomenon produces a significant cult diversification: several Roman associations, all different from one other in their practices and composition, honored Liber and his benefits.
