A horizon is a prospect, a perspective, a possibility. Paul’s pieces presented here deal with the impenetrability of what lies beyond that space where the earth ends and the sky begins.
Technically, a horizon is a perceived line that separates earth from sky, apparently. Or more precisely the line that divides all of the directions one can possibly look into two categories: those which intersect the earth’s surface, and those which do not.
But a horizon can also define a scope, or a limitation. A limitation may be an externally imposed restriction that cannot be sidestepped, a restricting flaw, a disadvantage or weakness within the viewer. Or alternatively the setting of a limit, the act of limiting, can be a restriction on damage, a protection from what is beyond, unknowable. These works seem to signify the limitation of view, and guide the viewer to a consideration of what is beyond the line of sight, what might exist in the gap, outside of limitations.
A horizon also separates day from night. Dawn - the twilight before sunrise - is recognized by the presence of weak sunlight, while the sun itself is still below the horizon. It is the precise moment after which the sky is no longer completely dark, formally, defined as the time at which the sun is 18 degrees below the horizon in the morning. Dusk is accepted as the time frame that occurs after twilight - when the sky is still bright, but no sun accompanies it, the period of the day after the sun has gone but before the sky has become dark. Strictly it is the time at which the sun is 6 degrees below the horizon in the evening. Objects are distinguishable, some stars and planets start to become visible to the naked eye.
These works then also deal with the coming of light and the onset of darkness, periods when something is about to start or about to finish. Not a definite statement, but a growing awareness of a beginning or an end. An apprehension or a confidence is imparted to the viewer. An impression is conveyed of coming well-being or misfortune.
What is presented here is also part henge. The original henge concept was to create a space separate from the outside world and firmly focus attention on an internal point. Henges were used as solar declinometers to measure the position of the rising or setting sun. There is a sense that some ceremony may unfold, that there is something taking place other than what can be seen. At the centre, attention is focused from the construction back onto the viewer.
The straight line of sight, the distance to the true horizon, can be expressed as d = √13h, where d is the distance to the apparent line, and h is the height above ground or sea level of the eye of the observer. A mathematical bent will indicate this to be true also for Paul’s pieces.
