The crossing of the border involves the passage of the border crosser from one territory to another, and the passage is marked by the border. The border crossed by the border crosser may be a physically marked border, or it may be an intangible line, often invisible in space. It can always be in addition a symbolic, temporal, or epistemological border. The territories involved may likewise be politically defined, but also be symbolic spheres or periods in time.
All borders must have a spatial dimension, imaginary or otherwise, or else one cannot cross them. As borders only can be seen from particular, embodied viewpoints, always situated on one side of the border, the border might be crossed by the gaze and other senses, before being crossed by the body. Border crossing may be successful or unsuccessful, or successful and unsuccessful at the same time on different planes.
The border crossing produces a border crossing narrative. Indeed, the structure of the border crossing is similar to that of the minimal narrative, with a protagonist moving from one situation to another, using a helper to overcome an antagonist.
