I have a theory about this, the Gothic arch, the next step in the evolution of Romanesque Barrel Vaulting. The clusters of vertical, collected, thin columns. The light shining in among the vertical elements. The color of the light. The upward thrust and the feeling of protection. The tops of the trees creating their canopy, the church's roof, like hands folded in prayer above us, in protection and praise.
I think Gothic architecture is us remembering the protection of the forest, from which we departed, headed out onto the savannas. Out there, we were exposed. Subsequently, we devised language so we could communicate and facilitate hunts and protective efforts quickly and efficiently.
But we always remembered the protection of the forest and we did so with awe.
I suggest that the forest is inspiration for these protective, inspiring, upward looking (toward God) Gothic environments, where we could find a memory.
What caused me to think this was a trip I made to Upstate NY, some years ago. I walked into a forest - a deep and very vertical one, tall and grand, and saw the light streaming in from above and around the trees. It was very, very quiet; calm; protective. Being there was almost a religious experience, in its respect and reverence for something greater than I.
