“I shivered. Of course, that was the whole point of the re-enactment, that we ourselves became the ghosts, learning to walk the land as they walked it two thousand years ago, to tend our fire as they tended theirs and hope that some of their thoughts, their way of understanding the world, would follow the dance of muscle and bone. To do it properly, I thought, we would almost have to absent ourselves from ourselves, leaving our actions, our re-enactions, to those no longer there. Who are the ghosts again, us or our dead? Maybe they imagined us first, maybe we were conjured out of the deep past by other minds.”
