event one:
the disappearance of the horizon as absolute reference

Orientation can involve the situation of oneself between an object and a boundary - the sun and the horizon, for example. In the vast prairie landscape of this promenade architecturale, one can be oriented between the enclosed box and the horizon. Entry to the promenade involves (for most) ducking and entering in to the enclosure, erasing from view the horizon as an absolute reference.
