“It is impossible to imagine ancient Greece without its sanctuaries.” (J. Whitley, Archaeology of Ancient Greece [Cambridge, U.K.: Cambridge University Press, 2001], 134). The same statement could be made for the Roman world. Sacred space was a key omnipresent tenet of ancient Greek and Roman societies—the physical manifestation of the degree to which the ancients dedicated time to the wide spectrum of gods who controlled their worlds. Since the 1990s, the study of sacred space has moved from one primarily undertaken by archaeologists and architects fixated on monumental structures (with the study of religious ritual conducted by scholars of religion mainly through literary and inscriptional sources), to one in which the space is understood as a dynamic and key component in the ritual process, an equal player in the creation of the human understanding and experience of the divine. Yet alongside this reconsideration of the importance of space in the dynamics of ritual, there has also been an increasing appreciation of the multiple roles sanctuaries played, and played host to, within the wider landscape. Sacred spaces are thus key players in the ordering of landscapes, they offer the potential for the development and scope of civic and individual power, and they act as the locus for identity development, civic competition, and the articulation of changing power balances in the wider world. Sacred space has as a result shed its fixed and positivist image: we recognize sacred spaces as everything from natural groves to massive architectural complexes—as places that are constantly changing and constantly being used simultaneously for a variety of sacred and secular activities, experienced and understood simultaneously in a multitude of ways by their different users, and that engage dynamically and heterogeneously with their surrounding secular environments.
