it.
Lights many the eighth sphere displays to you
Which in their quality and quantity
May noted be of aspects different.
If this were caused by rare and dense alone,
One only virtue would there be in all
Or more or less diffused, or equally.
Virtues diverse must be perforce the fruits
Of formal principles; and these, save one,
Of course would by thy reasoning be destroyed.
Besides, if rarity were of this dimness
The cause thou askest, either through and through
This planet thus attenuate were of matter,
Or else, as in a body is apportioned
The fat and lean, so in like manner this
Would in its volume interchange the leaves.
Were it the former, in the sun's eclipse
It would be manifest by the shining through
Of light, as through aught tenuous interfused.
This is not so; hence we must scan the other,
And if it chance the other I demolish,
Then falsified will thy opinion be.
But if this rarity go not through and through,
There needs must be a limit, beyond which
Its contrary prevents the further passing,
And thence the foreign radiance is reflected,
Even as a colour cometh back from glass,
The which behind itself concealeth lead.
Now thou wilt say the sunbeam shows itself
More dimly there than in the other parts,
By being there reflected farther back.
From this reply experiment will free thee
If e'er thou try it, which is wont to be
The fountain to the rivers of your arts.
Three mirrors shalt thou take, and two remove
Alike from thee, the other more remote
Between the former two shall meet thine eyes.
Turned towards these, cause that behind thy back
Be placed a light, illuming the three mirrors
And coming back to thee by all reflected.
Though in its quantity be not so ample
The image most remote, there shalt thou see
How it perforce is equally resplendent.
Now, as beneath the touches of warm rays
Naked the subject of the snow remains
Both of its former colour and its cold,
Thee thus remaining in thy intellect,
Will I inform with such a living light,
That it shall tremble in its aspect to thee.
Within the heaven of the divine repose
Revolves a body, in whose virtue lies
The being of whatever it contains.
The following heaven, that has so many eyes,
Divides this being by essences diverse,
Distinguished from it, and by it contained.
The other spheres, by various differences,
All the distinctions which they have within them
Dispose unto their ends and their effects.
Thus do these organs of the world proceed,
As thou perceivest now, from grade to grade;
Since from above they take, and act beneath.
Observe me well, how through this place I come
Unto the truth thou wishest, that hereafter
