They are the ground, the books, the academes

300 From whence doth spring the true Promethean fire.

[301] Why, universal plodding prisons up

The nimble spirits in the arteries,

As motion and long-during action tires

[304] The sinewy vigour of the traveller.

305 Now, for not looking on a woman’s face,

You have in that forsworn the use of eyes

And study too, the causer of your vow;

For where is any author in the world
