Illumination

Light.
It's pretty amazing. It travels at a constant speed but can withstand being bent, refracted and deflected. It shines for millennia and across impossible distances. It is the daylight, the provider of life for our world and similar stars guide us through the night too. As humans many cultures view light as divine. It is revered in festivals throughout the world. In those climes where the hours we receive alter with the changing seasons many view the loss of daylight with fear and celebrate its return with joy. Solar eclipses which rob the world of its life bestowing light in apparent bite sized chunks before its triumphant return have also been observed with awe and fear. Light can serve as a warning, telling us of danger or it can welcome us to shelter, warmth and safety. Light can be used to transfer messages, pictures, news. It is of almost immeasurable importance. Not so strange then, that it should be used to depict hope, for without it's guiding influence we are all lost.
