This final substantive chapter looks in detail at the festival of the Kalends of January as an extended case study for the persistence of popular culture in late antiquity. This distinctively late antique festival is examined from a number of angles, looking at its official and informal, public and private dimensions. Next, the longstanding ecclesiastical critique of the festival as ‘pagan’ is discussed. Key themes of the festival are then considered in turn, starting with the role of festive licence, often seen as a central feature of popular culture more broadly. The Kalends masquerades, including dressing up as animals and in the clothes of the opposite sex, are explored. Next the important element of gift exchange is discussed, providing a way in to look at the social and economic dimensions of the festival. In this way this chapter shows the continuing role of the festival in negotiating the unequal yet broadly stable social relations of late antique Provence, despite the hostility of the church.
