Shadows can be fun, mysterious, frightful, intentional, random, and even boring. Regardless of how they are viewed and make us feel, they can all be explained by a law of physics: light is interrupted by an opaque or semi-opaque object and darkness is created in the form of the object on the opposite side of the illuminated object.
The shape and degree of darkness are controlled by several factors: light intensity, angle of the light source illuminating the object, movement of the object or light source, opaqueness of the object being illuminated, location of the viewer with respect to the object, the terrain upon which the shadow falls, and the distance of the shadow.
In the case of this lengthy shadow, I was atop the lighthouse with a clear view of the shadow being cast. The sun was bright and at an angle as it was afternoon. The lighthouse was opaque, except for the glass windows which reveal the light fixture. Although the type of surface which accepted the shadow changes from land to water, both are relatively level and flat. Hence, the shadow is directly in-line with the lighthouse.
However, aside from a scientific explanation there is something else about shadows-perhaps something almost sinister. Our imaginations can run wild so-to-speak when we allow the shadow to come ‘alive’ in our minds. We ‘feel’ its presence which can send chills up our back and make us look over our shoulder repeatedly. Yet, logically, we know shadows are not alive, but they are attached to the object casting it via invisible cords. Those cords which lead us to the objects are what we really fear-the shadows only confirm their existence.
There are more to shadows than meets the eyes. It is what they reveal which makes them so special..so ethereal. Not only do they reveal a hint of the object casting the shadow, they often expose something deep inside of us which is only triggered by the faded image. When I gaze upon this scene I am reminded of warmth, relaxation and discovery-all very pleasant feelings. Fortunately, I viewed this shadow in bright circumstances and there was no negativity attached to it or the lighthouse. That is not always the case.
I recall a memory of shadows which affected me unexpectedly. Many years ago I hiked to the top of a 12,000 foot mountain in the Rockies of Colorado. The day was sunny and the weather pleasant. After a while I noticed dark, swiftly moving shadows rolling across the rocky terrain. Clouds, and then more clouds. Fast and then faster they came. With the sun blazing above them they cast menacing looking images onto the mountain top. I recall vividly how I suddenly felt so very small and insignificant in comparison to the grandeur of nature’s power. The majesty of the mountains coupled with a storm fast approaching made me very aware that had I stayed on top of that mountain when the full force of the storm passed over, I would not have returned from whence I started. I was amazed that all it took were shadows to evoke these thoughts and feelings.
With a slight chuckle I think of the movies with sinister plots and shadows which scare those acting as well as those viewing. Feelings of fearfulness and harm cause the heart to race-all because of shadows. Or, is it the shadows? Perhaps deeper reasons exist.
