“Lived ancient religion” offers a new perspective on ancient religion. It shares the priority on ritual of many studies from the late 19th century onward but reconstructs ancient religion not as a set of rules or coherent system but a dynamic field of change and tradition. The central notion is taken from contemporary religious studies. The concept of “lived religion” was developed in the late 1990s and has gained a growing reception ever since. Rather than analyzing expert theologies, dogma, or the institutional setting and history of organized religion, the focus of lived religion is on what people actually do: the everyday experience, practices, expressions, and interactions that are related to and constitute religion. In this way, religion is understood as a spectrum of experiences, actions, beliefs, and communications hinging on human interaction with super-human or even transcendent agent(s), usually conceptualized by the ancient Mediterraneans as gods. Material symbols, elaborate forms of representation, and ritualization are called upon for the success of communication with these addressees. The concept of lived religion has only recently been applied to the analysis of ancient religion. With a view to the dynamics of religion in the making, research based on this new concept critically engages with the notions of civic religion and (elective) cults as clearly defined rule- or belief-based systems. It stresses the similarity of practices and techniques of creating meaning and knowledge across a whole range of addressees of religious communication and in light of a high degree of local innovation. The emphasis is not on competing religions or cults but on symbols that are assuming ever-new configurations within a broad cultural space. The central notion of religious agency offers extended possibilities of imagination and intervention—of imagined, invoked, and even experienced divine support in real situations. In this way, the attribution of agency to divine actors provides appropriately creative strategies for the human agents (and sometimes even their audiences) to transcend the situation in question, whether by leading a ritual, casting a person as possessed, invoking means not yet available (as through a vow), or bolstering one’s own party with the favor of divine members. Religions, as seen from below, are the attempt—often by just a few individuals—to at least occasionally create order and boundaries through means other than a normative system imperfectly reproduced by humans. Such boundaries would include the notions of sacred and profane, pure and impure, public and private, as well as gendered conceptions of deities. Institutions such as professional priesthoods and the reformulation of religion as knowledge that is kept and elaborated by such professionals could constitute further features of crucial importance for sketching a history of such systems. This is religion in the making, though it casts itself as religion made forever. Acknowledging the individual appropriation and the production of meaning at play in these situations excludes the employment of only cultural interpretations, drawing on other parts of a dense and coherent web of meaning.
