This chapter brings the sensory potentialities of material objects used in Roman ritualized activities into discourse concerning the nature and production of ancient religious knowledge. By combining perspectives derived from lived religion and material religion it is argued that religious agency should be understood as the product of the intertwining of human and more-than-human things within assemblages. Lived experiences of this production of agency, in turn, cause people to feel and consequently think in certain ways, ultimately producing what can be categorized as distal and proximal forms of religious knowledge. The chapter uses the example of the frieze of the Vestal Virgins from the Ara Pacis Augustae to argue that different forms of ancient religious knowledge were actively created through a multiplicity of lived experiences of ritualized action that brought human and more-than-human material things together, rather than existing only as something that was expressed through ritual behaviours. Exploring the Vestals’ experience of ritualized encounters with material things makes it possible to establish new understandings of the real-world lived experiences and identities of these priestesses, offering significant insights into how individualized forms of religious knowledge could be sustained even in the context of shared communal or public rituals.

In 36 BC, after the battle of Naulochus, Octavian decided to dedicate a temple to Apollo in memory of his victory over Sextus Pompeius and to have it built on the Palatine, on the spot where lightning had struck, which was taken to be a sign.1 The temple, however, would not be erected until 28 BC, after the battle of Actium, and would both commemorate Naulochus and Actium. Apollo was effectively linked to the battle of Actium: after his victory, Octavian restored the temple of Apollo at the entrance of the Ambracian Gulf; he also consecrated a sanctuary to Apollo on the site of his camp at Actium.
