I'm coming down from a poetry month high, so my choice today is about the poet's eye. Thank you, William Shakespeare.
From A Midsummer Night's Dream
Spoken by Theseus at the beginning of Act 5
The lunatic, the lover, and the poet
Are of imagination all compact:
One sees more devils than vast hell can hold;
That is the madman. The lover, all as frantic,
Sees Helen's beauty in a brow of Egypt.
The poet's eye, in fine frenzy rolling,
Doth glance from heaven to earth, from earth to heaven;
And as imagination bodies forth
The forms of things unknown, the poet's pen
Turns them to shapes, and gives to airy nothing
A local habitation and a name.
Such tricks hath strong imagination,
That if it would but apprehend some joy,
It comprehends some bringer of that joy;
Or, in the night, imagining some fear,
How easy is a bush supposed a bear!
