Paradiso

The glory of Him who moveth everything
Doth penetrate the universe, and shine
In one part more and in another less.
Within that heaven which most his light receives
Was I, and things beheld which to repeat
Nor knows, nor can, who from above descends;
Because in drawing near to its desire
Our intellect ingulphs itself so far,
That after it the memory cannot go.
(La Divina Commedia, Paradiso, Canto I - Dante Alighieri)
