Copernicus which, incidentally, are wrong, but because he was not a citizen of Venice and was not employed here.
You can leave him out of it, even if they did burn him.
And by the by, for all our liberties I shouldn't advise you to make too free with a name that has been expressly anathematized
? by the church, not even here, no, not even here.
GALILEO Your protection of freedom of thought is rather good business, isn't it?
You get good teachers for low pay by pointing out that other towns are run by the Inquisition, which burns people. In return for protection from the Inquisition, your professors work for next to nothing.
? THE PROCURATOR You're being unfair. What good would it do you to have all the time you want for research if any witless monk of the Inquisition could simply suppress your ideas? No rose without thorns, Mr. Galilei, no prince without monks!
? GALILEO And what's the use of free investigation without free time to investigate? What happens to the results? Why don't you submit my work on the laws of falling bodies (He points at a sheaf of manuscript) to the gentlemen of the signoria and ask them if it's not worth a few scudi more.
THE PROCURATOR It's worth infinitely more, Mr. Galilei. GALILEO Not infinitely more, sir, but five hundred scudi more.
8
? THE PROCURATOR Only what brings in scudi is worth scudi. If. you want money, you'll have to come up with something different. If you have knowledge to sell, you can ask only as much as it earns the purchaser.
For instance, the philosophy Mr. Colombe is selling in Florence brings the prince at least ten thousand scudi a year. Granted, your laws of falling bodies raised some dust. They're applauding you in Paris and Prague. But the gentlemen who applaud don't pay the university of Padua what you cost it. Your misfortune, Mr. Galilei,is your field.
? GALILEO I get it: free trade, free research. Free trade in research, is that it?
? THE PROCURATOR But Mr. Galilei! How can you say such a thing? Permit me to observe that I don't fully appreciate your witticism. The flourishing trade of the republic is hardly to be sneered at. Much less can I, as long- time procurator of the university, countenance the, I must say, frivolous tone in which you speak of research. (While Galileo sends longing glances toward his worktable) Think of the world around us! The whip-of slavery under which science is groaning at certain universities--where old leather-bound tomes have been cut into whips. Where no one cares how the pebble falls, but only what Aristotle writes about it. The eyes have only one purpose: reading. What use are the new laws of gravity when the law of suavity is all that matters? And then think of the immense joy with which our republic accepts your ideas. Here you can do research! Here you can work! Nobody spies I on you, nobody oppresses you. Our merchants, who know the importance of better linen in their competition with Florence, listen with interest to your cry for "Better physics! And don't forget how much physics owes to the campaign for better looms! Our most eminent citizens--men for whom time is money--take an interest in your work, they come to see you and watch demonstrations of your discoveries. Don't despise trade, Mr. Galilei! None of us here would ever allow your work to be interfered with or permit outsiders to create difficulties for you. You've got to admit, Mr. Galilei, that this is the ideal place for your work!
GALILEO (in despair) Yes.
PROCURATOR Then the financial aspect: All you have to do is come up with
another invention as clever as that splendid proportional compass of yours which a person ignorant of mathematics can use to (He counts on his fingers) trace a line, compute compound interest, reproduce a land survey in enlarged or reduced scale, and determine the weight of cannon I balls.
GALILEO Flimflam.
THE PROCURATOR An invention that delighted and amazed our leading citizens
and brought in money--you call that flimflam. I'm told that even General Stefano Gritti can do square roots with it.
? CGALILEO Quite a gadget--all the same, Priuli, you've given me an idea. Priuli, I may have something along those lines for you. (He picks up the sheet with bis sketch)
? PROCURATOR Really? That would be the solution. (Gets up) Mr. Galilei, we know you are a great man. A great but ,f,'. dissatisfied man, if I may say so.
? GALILEO Yes, I am dissatisfied and that's what you should be paying me for if you had any sense. Because I'm dissatisfied with myself. But you do everything to make me dissatisfied with you, I admit it amuses me to do my bit for my Venetian friends, working in your great arsenal with its shipyards and armories. But you leave me no time to follow up the
9
? speculations which result from this work. You muzzle the ox that does your threshing. I'm forty-six years old and I've accomplished nothing that satisfies me.
THE PROCURATOR In that case I won't disturb you any longer. GALILEO Thank you.
(The procurator leaves, Galileo remains alone for a few moments and begins to
work. The Andrea comes running in)
GALILEO (at work) Why didn't you eat the apple?
ANDREA I need it to show her that the earth turns.
GALILEO I must tell you something, Andrea. Don't mention our ideas to
other people.
ANDREA GALILEO ANDREA GALILEO
Why not?
Our rulers have forbidden it.
But it's the truth.
Even so, they forbid it. And there's another reason. We still have no
proofs for what we know to be right. Eve the doctrine of the great
Copernicus is not yet proven. It only a hypothesis. Give me the lenses. ANDREA Half a scudo wasn't enough. I had to leave him my jacket. As a
pledge.
GALILEO How will you get through the winter without jacket?
(Pause. Galileo arranges the lenses on the sheet with the sketch)
ANDREA What's a hypothesis?
GALILEO It's when we consider something probable but have no facts. In the
face of the heavenly bodies we're like worms with dim eyes that see very little. The ancient doctrines that have been accepted for a thousand years are rickety. There's less solid timber in those immense edifices than in the props needed to keep them from collapsing. Too many laws that explain too little, whereas new hypothesis has few laws that explain a great deal.
ANDREA But you've proved it all to me. I want to be a physicist too, Mr. Galilei. GALILEO Very sensible in view of all the problems remaining to be solved in our
field. (He has gone to the window and looked through the lenses. Mildly
interested] Take a look, Andrea.
ANDREA Holy Mary! Everything comes close. The bells of the campanile are
right here. I can even read the copper letters: GRACIA DEI. . GALILEO It'll get us five hundred scudi.

Galileo presents a new invention to the republic of Venice.
No one's virtue is complete: Great Galileo liked to eat. You will not resent, we hope The truth about his telescope.
The great arsenal of Venice near the harbor. Senators, headed by the 1'doge. On one side Galileo's friend Sagredo and Virginia Galilei, fifteen; Isbe is holding a velvet cushion on which lies a telescope about two feet ''long, encased in red leather. Galileo is standing on a dais. Behind him the tripod for the telescope; the lens grinder Federzoni is in charge
? GALILEO Your Excellency, august signoria! As professor of mathematics at your university in Padua and director of the great arsenal here in
Venice, I have always felt it incumbent upon me not only to fulfill my duties as a teacher but also to procure special advantages to the republic of V enice by means of useful inventions. With great satisfaction and in all due humility, I shall demonstrate and present to you today an entirely new instrument, my spyglass or telescope, manufactured in your world-famous great arsenal in accordance with the highest scientific and Christian principles, the fruit of seventeen years of your obedient servant's patient labors.
(Galileo leaves the dais and stands next to Sagredo)
(Applause, Galileo takes a bow)
GALILEO (softly to Sagredo) What a waste of time!
SAGREDO (softly) You'll be able to pay the butcher, old friend.
GALILEO Yes, they'll make money on it. (Makes another bow)
THE PROCURATOR (steps up on the dais) Your Excellency, august signoria! Once
again a glorious page in the great book of human accomplishments is being written in Venetian characters. (Polite applause) A scholar of world renown is presenting to you, and to you alone, a highly salable tube for you to manufacture and market at your pleasure. (Stronger applause) Has it occurred to you that in the event of war this instrument will enable us to recognize the nature and number of the enemy's ships at least two hours before they have a clear view of ours and, in full cognizance of his strength, decide whether to pursue, engage or withdraw? (Loud applause) And now, Your Excellency, august signoria, Mr. Galilei bids you accept this instrument of his invention, this evidence of his genius, from the hands of his charming daughter.
(Music. Virginia steps forward, bows, hands the telescope to the procurator. The doge and the senators mount the dais and look through the tube)
GALILEO (softly) I can't promise to go through with this farce. They think they're getting a profitable gadget, but it's much more than that. Last night I turned the tube on the moon.
SAGREDO What did you see?
11
? GALILEO It has no light of its own.
SAGREDO What?
GALILEO I tell you, astronomy has been marking time for a thousand years for lack of a telescope.
SENATOR SAGREDO SENATOR
GALILEO SAGREDO GALILEO SENATOR
Mr. Galilei! You're wanted.
One sees too well with that thing. I'll have to warn my ladies to stop bathing on the roof.
Do you know what the Milky Way consists of? No.
I do.
A thing like that is worth its ten scudi, Mr. Galilei.
(Galileo bows)
VIRGINIA (takes Ludovico to her father) Ludovico wants to congratulate you,
father.
LUDOVICO (embarrassed] Congratulations, sir.
GALILEO I've improved on it.
LUDOVICO So I see, sir. You made the casing red. In Holland it was green. GALILEO (turns to Sagredo) I wonder if I couldn't prove a certain doctrine with
that thing. SAGREDO Watch your step!
THE PROCURATOR Your five hundred scudi are in the bag, Mr. Galilei. GALILEO (paying no attention to him) Of course, I'm always wary of rash
conclusions.
(The doge, a fat, modest man, has approached Galileo and is attempting, with clumsy dignity, to address him)
VIRGINIA LUDOVICO VIRGINIA LUDOVICO VIRGINIA LUDOVICO
Did I do it all right?
It seemed all right to me.
What's the matter?
Oh, nothing. A green casing might have done just as well.
I think they're all very pleased with father.
And I think I'm beginning to understand something about science.

January 10, 1610: By means of the telescope Galileo discovers celestial phenomena which prove the Copernican system. Warned by his friend of the possible consequences of his investigations, Galileo affirms his faith in reason.
January ten, sixteen ten: Galileo Galilei abolishes heaven.
Galileo's study in Padua. Night. Galileo and Sagredo, both in heavy overcoats, at the telescope.
? SAGREDO (looking through the telescope, in an undertone) The edge of the crescent is quite irregular, rough and serrated. In the dark part near the luminous edge there are luminous points. They are emerging, one after another. From these points the light spreads out over wider and wider areas and finally merges with the larger luminous part.
GALILEO How do you account for those luminous points? SAGREDO It can't be.
GALILEO But it is. They're mountains.
SAGREDO On a star?
GALILEO Gigantic mountains. Their peaks are gilded by the rising sun while the surrounding slopes are still deep in darkness. You can see the light descending from the highest peaks into the valleys.
SAGREDO But that contradicts all the astronomy of two thousand years. GALILEO True. No mortal has ever seen what you are seeing, except me. You're
the second.
SAGREDO But the moon can't be another earth with mountains and valleys, any
more than the earth can be a planet.
GALILEO The moon can be an earth with mountains and valleys, and the earth can be a planet. Simply another heavenly body, one among thousands. Take another look. Is the dark part of the moon entirely dark?
SAGREDO No. When I look closely, I see a feeble gray light on it.
GALILEO SACREDO GALILEO SAGREDO
What can that light be? ?
It's from the earth.
Nonsense. How can the earth with its mountains and forests and
oceans--a cold body--give light?
GALILEO The same way the moon sheds light. Because both bodies are
illuminated by the sun, that's why they shed light. What the moon is to us we are to the moon. The moon sees us by turns as a crescent, as a half- circle, as full, and then not at all.
SAGREDO GALILEO SAGREDO
Then there's no difference between moon and earth? Apparently not.
Less than ten years ago a man was burned in Rome. His name was Giordano Bruno and he had said the same thing.
13
GALILEO I know. But we can see it. Keep your eyes to the tube. What you see is that there's no difference between heaven and earth. This is the tenth of January. Humanity notes in its diary: Heaven abolished.
SAGREDO It's terrifying.
GALILEO I've discovered something else. Perhaps something even more amazing.
MRS. SARTI (comes in) The procurator.
(The procurator rushes in)
THE PROCURATOR I apologize for the late hour. I'd be much obliged if we could talk privately.
GALILEO Mr. Sagredo can hear anything I can hear, Mr. Priuli.
THE PROCURATOR It might embarrass you to have the gentleman hear what has
happened. Unfortunately, it's something quite incredible.
GALILEO Mr. Sagredo is used to hearing incredible things in my presence.
THE PROCURATOR I wonder. (Pointing at the telescope) There it is, your splendid gadget.
You might as well throw it away. It's worthless, absolutely worthless. SAGREDO (who has been restlessly pacing the floor) What do you mean?
THE PROCURATOR Do you realize that this invention of yours, "the fruit of seventeen
years of patient labor," is for sale on every street corner in Italy for a couple of scudi? Made in Holland, I might add. At this very moment a Dutch freighter is unloading five hundred telescopes in the harbor.
GALILEO You don't say.
THE PROCURATOR Your equanimity, sir, is beyond me.
SAGREDO I fail to see what's troubling you. Let me tell you that just in these last few
days Mr. Galilei--with this very instrument--has made the most
revolutionary discoveries concerning heavenly bodies.
GALILEO (laughing) Have a look for yourself, Priuli.
THE PROCURATOR Let me tell you that after having Mr. Galilei's salary doubled on the
strength of this worthless gadget I'm quite satisfied with the discovery I've already made. It's sheer accident that when the gentlemen of the signoria first looked through your tube, confident of having acquired something for the republic that could be manufactured only here, they failed to see--seven times magnified--a common peddler on the next corner hawking that same tube for a song. (Galileo roars with laughter)
SAGREDO Dear Mr. Priuli, I may not be able to judge the instrument's value to the economy, but its value to philosophy is so enormous that . . .
THE PROCURATOR To philosophy! What business has Mr. Galilei, a mathematician, meddling with philosophy? Mr. Galilei, you once invented a very respectable pump for the city; your irrigation system functions. The weavers, too, are very pleased with your machine. How on earth could I have anticipated anything like this?
GALILEO Not so fast, Priuli. Sea routes are still long, unsafe and expensive. We lack a dependable clock in the sky. A guide to navigation. I have reason to believe that with the telescope we can very clearly perceive certain stars with very regular motions. New star charts, Mr. Priuli, could save the shipping interests millions of scudi.
THE PROCURATOR Forget it. I've heard more than enough. In return for my kindness you've made me the laughingstock of the city. I'll be remembered as the procurator who fell for a worthless telescope. You have every reason to laugh. You've got your five hundred scudi. But I'm telling you, and I speak as an honest man: This world makes me sick! (He leaves, banging the door behind him)
? 14
? GALILEO He's rather likable when he gets angry. Did you hear what he said; A world where you can't do business makes him sick.
SAGREDO Did you know about the Dutch instruments?
GALILEO Of course. From hearsay. But the one I made for those skinflints in the
signoria is twice as good. How can I do my work with the bailiff at the door? And Virginia will need her trousseau soon, she's not bright. Besides, I like to buy books, and not only about physics, and I like to eat well. I get my best ideas over a good meal. A rotten time to live in! They weren't paying me as much as the teamster who carts their wine barrels. Four cords of firewood for two courses in mathematics. I've wormed five hundred scudi out of them, but I've got debts, some of them twenty years old. Give me five years of leisure and I'll prove everything. Let me show you something else.
SAGREDO (hesitates to go to the telescope) I almost think I'm afraid, Galileo.
GALILEO I want to show you a milky-white patch of luminous mist in the galaxy.
Tell me what it's made of.
SAGREDO Why, stars, countless stars.
GALILEO In the constellation of Orion alone there are five hundred fixed stars. Those
are the many worlds, the countless other worlds, the stars beyond stars that the man they burned talked about. He didn't see them, but he knew they would be there.
SAGREDO Even if our earth is a star, it's still a long way to Copernicus' contention that the earth revolves around the sun. There isn't any star in the heavens with another revolving around it. And the earth, you'll have to admit, has the moon revolving around it.
GALILEO Sagredo, I wonder. I've been wondering for two days. There's Jupiter. (He adjusts the telescope) Now, near it there are four smaller stars that you can only make out through the tube. I saw them on Monday but I didn't
pay too much attention to their positions. Yesterday I looked again. I could have sworn that all four had moved. I recorded their positions. Now they're different again. What's that now? There were four of them. (Getting excited) You look!
SAGREDO I see three.
GALILEO Where's the fourth? Here are the tables. We must compute the
movements they can have made. (Agitated, they sit down to work. The stage turns dark, but on a cyclorama Jupiter and its satellites remain visihle. When it grows light again, they are still sitting there in their winter coats
GALILEO Now we have proof. The fourth must have moved behind Jupiter where we can't see it. There you have a star with another revolving around it.
SAGREDO But the crystal sphere that Jupiter is fastened to?
GALILEO Where is it indeed? How can Jupiter be fastened to anything if other
stars revolve around it? There is no scaffolding in the sky, there's nothing
holding the universe up! There you have another sun!
SAGREDO Calm down. You're thinking too fast.
GALILEO Fast, hell! Man, get excited! You're seeing something that nobody ever
saw before. They were right!
SAGREDO Who? The Copernicans?
GALILEO Yes, and you know who. The whole world was against them, and
yet they were right. That's something for Andrea! (Beside himself, he runs to
the door and shouts) Mrs. Sarti! Mrs. Sarti! SAGREDO Galileo, please calm yourself!
15
? GALILEO Sagredo, please get excited! Mrs. Sarti!
SAGREDO (turning the telescope aside) Will you stop yelling like a fool?
? GALILEO Will you stop standing there like a stockfish whenwe've discovered the truth? SAGREDO I'm not standing here like a stockfish, I'm trembling
for fear it's the truth. GALILEO What?
SAGREDO Have you taken leave of your senses? Don't you realize what you're getting into if what you see is really true? And if you go shouting all over town that the earth is a planet
and not the center of the universe?
GALILEO Yes, and that the whole enormous cosmos with all its stars doesn't revolve around our tiny earth, as anyone could have guessed anyway.
SAGREDO So that there's nothing but stars! --But where does that put God? GALILEO What do you mean?
SAGREDO God! Where's God?
GALILEO (furious) Not out there! Any more than He'd be on earth if somebody
looking for Him here, SAGREDO Where is God then?
out there started
Am I a theologian? I'm a mathematician.
First of all you're a human being. And I ask you: Where is God in your world system?

GALILEO SAGREDO GALILEO SAGREDO

That's why he was burned! Less than ten years ago!
Because he couldn't prove it! Because all he could do was say so! Mrs. Galileo, I know you're a clever man. For three years in Pisa and
Sarti!
Inside us or nowhere!
seventeen here in Padua you've patiently instructed hundreds of students in the Ptolemaic system as advocated by the church and confirmed by the scriptures on which the
church is grounded. Like Copernicus you thought it was wrong, but you taught it. GALILEO Because I couldn't prove anything.
SAGREDO (incredulous) You think that makes a difference?
GALILEO All the difference in the world! Look here, Sagredo! I believe in man and that means I believe in reason. Without that belief I wouldn't have the strength to get out of bed in the morning.
? SAGREDO Then let me tell you this: I don't believe in reason. Forty years' experience has taught me that human beings are not accessible to reason.
? by the church, not even here, no, not even here.
GALILEO Your protection of freedom of thought is rather good business, isn't it?
You get good teachers for low pay by pointing out that other towns are run by the Inquisition, which burns people. In return for protection from the Inquisition, your professors work for next to nothing.
? THE PROCURATOR You're being unfair. What good would it do you to have all the time you want for research if any witless monk of the Inquisition could simply suppress your ideas? No rose without thorns, Mr. Galilei, no prince without monks!

THE PROCURATOR It's worth infinitely more, Mr. Galilei. GALILEO Not infinitely more, sir, but five hundred scudi more.
8
? THE PROCURATOR Only what brings in scudi is worth scudi. If. you want money, you'll have to come up with something different. If you have knowledge to sell, you can ask only as much as it earns the purchaser.
For instance, the philosophy Mr. Colombe is selling in Florence brings the prince at least ten thousand scudi a year. Granted, your laws of falling bodies raised some dust.

THE PROCURATOR Your five hundred scudi are in the bag, Mr. Galilei. GALILEO (paying no attention to him) Of course, I'm always wary of rash
conclusions.
(The doge, a fat, modest man, has approached Galileo and is attempting, with clumsy dignity, to address him)

Did I do it all right?
It seemed all right to me.
What's the matter?
Oh, nothing. A green casing might have done just as well.
I think they're all very pleased with father.
And I think I'm beginning to understand something about science.

January 10, 1610: By means of the telescope Galileo discovers celestial phenomena which prove the Copernican system. Warned by his friend of the possible consequences of his investigations, Galileo affirms his faith in reason.
January ten, sixteen ten: Galileo Galilei abolishes heaven.
Galileo's study in Padua. Night. Galileo and Sagredo, both in heavy overcoats, at the telescope.
? SAGREDO (looking through the telescope, in an undertone) The edge of the crescent is quite irregular, rough and serrated. In the dark part near the luminous edge there are luminous points. They are emerging, one after another. From these points the light spreads out over wider and wider areas and finally merges with the larger luminous part.
GALILEO How do you account for those luminous points? SAGREDO It can't be.
GALILEO But it is. They're mountains.
SAGREDO On a star?
GALILEO Gigantic mountains. Their peaks are gilded by the rising sun while the surrounding slopes are still deep in darkness. You can see the light descending from the highest peaks into the valleys.
SAGREDO But that contradicts all the astronomy of two thousand years. GALILEO True. No mortal has ever seen what you are seeing, except me. You're
the second.
SAGREDO But the moon can't be another earth with mountains and valleys, any
more than the earth can be a planet.
GALILEO The moon can be an earth with mountains and valleys, and the earth can be a planet. Simply another heavenly body, one among thousands. Take another look. Is the dark part of the moon entirely dark?
SAGREDO No. When I look closely, I see a feeble gray light on it.
GALILEO SACREDO GALILEO SAGREDO
What can that light be? ?
It's from the earth.
Nonsense. How can the earth with its mountains and forests and
oceans--a cold body--give light?
GALILEO The same way the moon sheds light. Because both bodies are
illuminated by the sun, that's why they shed light. What the moon is to us we are to the moon. The moon sees us by turns as a crescent, as a half- circle, as full, and then not at all.
SAGREDO GALILEO SAGREDO
Then there's no difference between moon and earth? Apparently not.
Less than ten years ago a man was burned in Rome. His name was Giordano Bruno and he had said the same thing.
13
GALILEO I know. But we can see it. Keep your eyes to the tube. What you see is that there's no difference between heaven and earth. This is the tenth of January. Humanity notes in its diary: Heaven abolished.
SAGREDO It's terrifying.
GALILEO I've discovered something else. Perhaps something even more amazing.
MRS. SARTI (comes in) The procurator.
(The procurator rushes in)
THE PROCURATOR I apologize for the late hour. I'd be much obliged if we could talk privately.
GALILEO Mr. Sagredo can hear anything I can hear, Mr. Priuli.
THE PROCURATOR It might embarrass you to have the gentleman hear what has
happened. Unfortunately, it's something quite incredible.
GALILEO Mr. Sagredo is used to hearing incredible things in my presence.
THE PROCURATOR I wonder. (Pointing at the telescope) There it is, your splendid gadget.
You might as well throw it away. It's worthless, absolutely worthless. SAGREDO (who has been restlessly pacing the floor) What do you mean?
THE PROCURATOR Do you realize that this invention of yours, "the fruit of seventeen
years of patient labor," is for sale on every street corner in Italy for a couple of scudi? Made in Holland, I might add. At this very moment a Dutch freighter is unloading five hundred telescopes in the harbor.
GALILEO You don't say.
THE PROCURATOR Your equanimity, sir, is beyond me.
SAGREDO I fail to see what's troubling you. Let me tell you that just in these last few
days Mr. Galilei--with this very instrument--has made the most
revolutionary discoveries concerning heavenly bodies.
GALILEO (laughing) Have a look for yourself, Priuli.
THE PROCURATOR Let me tell you that after having Mr. Galilei's salary doubled on the
strength of this worthless gadget I'm quite satisfied with the discovery I've already made. It's sheer accident that when the gentlemen of the signoria first looked through your tube, confident of having acquired something for the republic that could be manufactured only here, they failed to see--seven times magnified--a common peddler on the next corner hawking that same tube for a song. (Galileo roars with laughter)
SAGREDO Dear Mr. Priuli, I may not be able to judge the instrument's value to the economy, but its value to philosophy is so enormous that . . .
THE PROCURATOR To philosophy! What business has Mr. Galilei, a mathematician, meddling with philosophy? Mr. Galilei, you once invented a very respectable pump for the city; your irrigation system functions. The weavers, too, are very pleased with your machine. How on earth could I have anticipated anything like this?
GALILEO Not so fast, Priuli. Sea routes are still long, unsafe and expensive. We lack a dependable clock in the sky. A guide to navigation. I have reason to believe that with the telescope we can very clearly perceive certain stars with very regular motions. New star charts, Mr. Priuli, could save the shipping interests millions of scudi.
THE PROCURATOR Forget it. I've heard more than enough. In return for my kindness you've made me the laughingstock of the city. I'll be remembered as the procurator who fell for a worthless telescope. You have every reason to laugh. You've got your five hundred scudi. But I'm telling you, and I speak as an honest man: This world makes me sick! (He leaves, banging the door behind him)
? 14
? GALILEO He's rather likable when he gets angry. Did you hear what he said; A world where you can't do business makes him sick.
SAGREDO Did you know about the Dutch instruments?
GALILEO Of course. From hearsay. But the one I made for those skinflints in the
signoria is twice as good. How can I do my work with the bailiff at the door? And Virginia will need her trousseau soon, she's not bright. Besides, I like to buy books, and not only about physics, and I like to eat well. I get my best ideas over a good meal. A rotten time to live in! They weren't paying me as much as the teamster who carts their wine barrels. Four cords of firewood for two courses in mathematics. I've wormed five hundred scudi out of them, but I've got debts, some of them twenty years old. Give me five years of leisure and I'll prove everything. Let me show you something else.
SAGREDO (hesitates to go to the telescope) I almost think I'm afraid, Galileo.
GALILEO I want to show you a milky-white patch of luminous mist in the galaxy.
Tell me what it's made of.
SAGREDO Why, stars, countless stars.
GALILEO In the constellation of Orion alone there are five hundred fixed stars. Those
are the many worlds, the countless other worlds, the stars beyond stars that the man they burned talked about. He didn't see them, but he knew they would be there.
SAGREDO Even if our earth is a star, it's still a long way to Copernicus' contention that the earth revolves around the sun. There isn't any star in the heavens with another revolving around it. And the earth, you'll have to admit, has the moon revolving around it.
GALILEO Sagredo, I wonder. I've been wondering for two days. There's Jupiter. (He adjusts the telescope) Now, near it there are four smaller stars that you can only make out through the tube. I saw them on Monday but I didn't
pay too much attention to their positions. Yesterday I looked again. I could have sworn that all four had moved. I recorded their positions. Now they're different again. What's that now? There were four of them. (Getting excited) You look!
SAGREDO I see three.
GALILEO Where's the fourth? Here are the tables. We must compute the
movements they can have made. (Agitated, they sit down to work. The stage turns dark, but on a cyclorama Jupiter and its satellites remain visihle. When it grows light again, they are still sitting there in their winter coats
GALILEO Now we have proof. The fourth must have moved behind Jupiter where we can't see it. There you have a star with another revolving around it.
SAGREDO But the crystal sphere that Jupiter is fastened to?
GALILEO Where is it indeed? How can Jupiter be fastened to anything if other
stars revolve around it? There is no scaffolding in the sky, there's nothing
holding the universe up! There you have another sun!
SAGREDO Calm down. You're thinking too fast.
GALILEO Fast, hell! Man, get excited! You're seeing something that nobody ever
saw before. They were right!
SAGREDO Who? The Copernicans?
GALILEO Yes, and you know who. The whole world was against them, and
yet they were right. That's something for Andrea! (Beside himself, he runs to
the door and shouts) Mrs. Sarti! Mrs. Sarti! SAGREDO Galileo, please calm yourself!
15
? GALILEO Sagredo, please get excited! Mrs. Sarti!
SAGREDO (turning the telescope aside) Will you stop yelling like a fool?
? GALILEO Will you stop standing there like a stockfish whenwe've discovered the truth? SAGREDO I'm not standing here like a stockfish, I'm trembling
for fear it's the truth. GALILEO What?
SAGREDO Have you taken leave of your senses? Don't you realize what you're getting into if what you see is really true? And if you go shouting all over town that the earth is a planet
and not the center of the universe?
GALILEO Yes, and that the whole enormous cosmos with all its stars doesn't revolve around our tiny earth, as anyone could have guessed anyway.
SAGREDO So that there's nothing but stars! --But where does that put God? GALILEO What do you mean?
SAGREDO God! Where's God?
GALILEO (furious) Not out there! Any more than He'd be on earth if somebody
looking for Him here, SAGREDO Where is God then?

First of all you're a human being. And I ask you: Where is God in your world system?

SAGREDO (shouting) As the man who was burned said?
GALILEO SAGREDO GALILEO SAGREDO
As the man who was burned said!
That's why he was burned! Less than ten years ago!
Because he couldn't prove it! Because all he could do was say so! Mrs. Galileo, I know you're a clever man. For three years in Pisa and
Sarti!
Inside us or nowhere!
seventeen here in Padua you've patiently instructed hundreds of students in the Ptolemaic system as advocated by the church and confirmed by the scriptures on which the
church is grounded. Like Copernicus you thought it was wrong, but you taught it. GALILEO Because I couldn't prove anything.
SAGREDO (incredulous) You think that makes a difference?
GALILEO All the difference in the world! Look here, Sagredo! I believe in man and that means I believe in reason. Without that belief I wouldn't have the strength to get out of bed in the morning.
? SAGREDO Then let me tell you this: I don't believe in reason. Forty years' experience has taught me that human beings are not accessible to reason.
