We draw a horizon to initiate a world: Once 'One' is divided, things can grow. This horizon is written-drawn with the words Sunset/Sunrise. While the horizon defines difference in space, sunset/sunrise defines difference in time. As metaphor for future, who owns the horizon?
In English, sunset and sunrise point to a human-centric experience - the sun doesn't rise nor sink. In Arabic, the words are derived from the words east (ghoroob) and west (shorooq), pointing to geographically-coordinated language. In Hebrew the words translate into shine (zrikha - root of 'east') and submerge (shki'a).
