The most difficult test of vision
Is to see that which cannot be seen.
I tell you, and so too will St. Paul,
To look -- There! -- for the unseen thing, which
is not the clear water only seen
through nor the aim of the basilisk
stare now fixed by time’s moving image.
Better one, two, about the same?
Better three, four, about the same?
Now look at that and tell me what you see.”
