Some of our strangest behaviors are performed in the interest of self-preservation, a sort of primal vanity that comes out when we try to remember and be remembered. We have developed public rituals around remembering the past in the form of re-enactments, choreographed performances designed for members of a community to tap into a time-swept culture, place, or event. Generations of hobbyists, in full period costume, flock to the spot at which something of perceived importance took place, to ceremoniously re-stage the original course of history as they imagine it.
But such events are reflective more of broad public imagination than historical reality, and done, in part, simply for the fun of charging at your best friend with a lance in one arm and a hand-made rusty iron shield in the other.
