Some learnèd men, which think1 to reason well,
Say light and color in the brain do dwell,
That motion in the brain doth light beget,2
And if no brain, the world in darkness shut.3
But be it4 that the brain hath eyes to see, 5
Then5 eyes and brain would6 make the light to be.
If so, poor Donne was out when he did say
If all the world were blind, ’twould still be day.
Say they, light would not in the air7 reign,
Unless you’ll grant8 the world were one great brain. 10
Some ages in some opinions all agree;9
The next doth strive to make them false to be.
But10 what is new doth all so pleasing sound,11
That reasons old are as mere nonsense found.12
But all opinions are by fancy fed, 15
And truth lies under those opinions,13 dead.

Of Light
Of Shadow and Echo
A shadow fell in love with the17 bright light,
Which makes her walk perpetually18 in his19 sight.
And when he’s absent, then, poor soul, she dies,
But when he shows himself, her life revives.
She sister is to Echo loud and clear, 5
Whose voice is heard, but no body20 appear.
She hates to see or show herself to men,
Unless Narcissus could live once21 again.
But these two souls (for they no bodies have)22
Do wander in the air to seek a grave. 10
Silence would bury one,23 the other night;
Both are24 denied by Repercussion’s25 spite.
And each of these are subject to the sense:26
One strikes the ear, shadow the eye presents.27
Of the Sound and Echo
A sound29 seems nothing, yet a while it lives,30
And like a wanton lad, mock answers gives,31
Not like the souls that from the bodies32 go,
For echo hath a body33 of air, we know.
But34 strange it35 is that sounds36 so strong and clear 5
Resisting bodies have, yet37 not appear,
But38 air, which subtle is, encounter may:
Thus words as sounds may with self-echo39 play.
But they grow weary soon, hold not40 out long,
Seem41 out of breath, and falter with the tongue. 10
What Makes Echo Rebound
Rebounds resisting substance must work on,43
Both in itself, and what it beats upon,44
For yielding bodies which do bow or break
Can ne’er rebound, nor like an45 echo speak.
Then every word of aïr forms46 a ball, 5
And every letter like a ball doth fall.
Words are condensèd air, which heard, do grow
As water which by cold doth turn to snow.
And as when snow is pressed hard balls become,47
So words being pressed as balls do backward run.48 10
What Makes Echo
The same motion which from the mouth doth move49
Runs through the air, which we by echo prove.50
As several letters in one word do join,51
So several figures through the air combine.
The air is wax, words seal, and give the print, 5
And so52 an echo in the air do mint.
And while those figures last, they life53 maintain;
When motion wears them out, echo is54 slain.
As sugar in the mouth doth melt with55 taste,
So echo in the air itself doth waste. 10
The Sun is Nurse to All the Earth Bears.
A Fire is in the Center of the Earth.
63
As heat about the heart always64 keeps nigh,
So doth a fire about the65 center lie.
This heat disperses66 through the body round,
And when that heat is not,67 no life is found.
So this heat68 makes all things to bud69 and bear, 5
Although the sun’s hot beams do ne’er come there.
Yet doth the sun nourish all things70 without,
Though71 fire within the Earth gives life, no doubt.
Thus72 heat within begets with child the Earth,
And heat without is midwife to her birth. 10
Of the Sun’s Weakness
Of the Motion of the Sun
Sometimes we find it hot, and sometimes cold,
Yet equal in degrees the sun77 doth hold.
And in a winter’s day more heat have78 found
Than summer, when the sun should parch the ground.
For if this79 heat doth make him gallop fast, 5
’T must80 ever equal be, or stay his haste.
If so, then seas which send up vapor may81
His fiery courage cool in the midway.82
Besides, the middle region, which is cold
And full of ice, will of his strength take hold. 10
Then ’tis not heat that makes him run so fast,
But running fast doth heat upon Earth83 cast,
And Earth sends vapors cold to quench his heat,84
Which break his strength, and make85 his beams so weak.
