When we look down into the blueness of some little pool, rejoicing in the birdlike passage of the clouds, and then look up to the wide sky, we realise that the finite is like a lake which, as far as its capacity allows, mirrors the infinite; and when we see the foreshorthened image of a poplar stretched in pale colouring beneath it, we have a sudden vision of time as the faint, straitened shadow of eternity. - Mary Webb
