“Thine eyes are springs in whose serene
And silent waters heaven is seen;
Their lashes are the herbs that look
On their young figures in the brook.”

Directive (1947)
Context: p>This was no playhouse but a house in earnest.
Your destination and your destiny's
A brook that was the water of the house,
Cold as a spring as yet so near its source,
Too lofty and original to rage.(We know the valley streams that when aroused
Will leave their tatters hung on barb and thorn.)</p

Letter to the Grand Duchess Christina (1615)
Context: Some years ago, as Your Serene Highness well knows, I discovered in the heavens many things that had not been seen before our own age. The novelty of these things, as well as some consequences which followed from them in contradiction to the physical notions commonly held among academic philosophers, stirred up against me no small number of professors — as if I had placed these things in the sky with my own hands in order to upset nature and overturn the sciences. They seemed to forget that the increase of known truths stimulates the investigation, establishment, and growth of the arts; not their diminution or destruction.<!-- ¶1
