The sable shadows, for in large degrees
This air is nimbler, nicer, and more strong.
And soon as ever 'thas filled and oped with light

Black air had blocked, there follow straightaway
Those films of things out-standing in the light,
Provoking vision- what we cannot do
From out the light with objects in the dark,

Followeth in, and fills each aperture
And thus blockades the pathways of the eyes
That there no images of any things
Can be thrown in and agitate the eyes.

The squared towers of a city, oft
Rounded they seem,- on this account because
Each distant angle is perceived obtuse,
Or rather it is not perceived at all;

And perishes its blow nor to our gaze
