Cathedral and reflection

It’s not often you see the shadows of gargantuan buildings cast across the sky like this. Shadows, I think, are usually perceived as personal ones or perhaps of trees whose forms create a small area of shade on the ground. No one comments on them much, they are voids more than statements. Seeing this reflection/projection, that of Salisbury Cathedral on the overcast night sky felt more like a cosmic event - like a comet or meteor shower or eclipse. The ground-set floodlights were the source of the reflection, its rays shooting up every corner, wall, gargoyle and saint and reforming, haloed, in the sky. What does it all mean?
