Citing Edmonds (1999, 7), Coyne suggests that "people experienced the world physically through a 'technology of memory,' in the way that they interact with certain monuments or landscapes, and that much of what happens in these places is constituted by the past by real or invented tradition and by what is already there. This 'technology of memory' allows people to re-use, re-absorb and re-work the past through their physical encounter with particular monuments or ritual events."
