In no other way have I seen of my own unaided sight that the world is round. As I watch, it arches its back, and each layer of the landscape bristles – though 'bristles' is a word of too much commotion for it. Details are no longer part of a grouping in a picture of which I am the focal point, the focal point is everywhere. Nothing has reference to me, the looker. This is how the Earth must see itself.
