Horizon exists as the ultimate symbol of life and death.
It seems as if horizontal line acitvates the longing for life (or death) in a human. Over many centuries, human civilization thought out a piece of "heaven" on earth from these horizons. Especially in places where the horizon or the oceanline is clearly visible; such as the Okinawan Islands and African Savanah.
