of the Late Antique Roman Empire, this study raises central questions concerning the development of pagan traditions in the context of the increasing influence of Christianity: which mechanisms and factors determined the fate of pagan celebrations? In how far did local peculiarities influence the persistence of traditional feast days? How can we explain the sometimes heterogeneous development of some pagan feasts - from rapid disappearance to continued persistence - and where were the limits of religious change? Tackling these questions promises not only a better understanding of pagan celebration culture in Late Antiquity, but also of the religious transformations of this period more generally.
