Cartophilus bowed. “Oh, Your Eminence, thank you, of course you are right. Although, possibly, I wonder if he may now be past the, the …”
“Past the worst of it?”
“I don’t know. But it’s always one thing at a time with him, Your Serenity.”
“Yes? Oh, yes. Well, I have been trying to give him something else to think about. But maybe it should be more direct.”
“A fine idea, Your Grace.”
The archbishop’s grin was like a schoolboy’s. “I’ve got just the man in mind.”
“Not an astronomer, I trust.”
Piccolomini laughed and gave the old servant a touch to the head that was half blessing, half schoolboy tap. And in the days following he invited several of the local natural philosophers of Siena to come to the palazzo and speak with Galileo. He asked them to initiate discussions about the strength of materials, magnetism, and similarly earth-bound topics. They did that, keeping resolutely away from the old man’s sore point, even to the point of spending much time looking through a microscope at the spectacular articulations of moths and fleas.
And while in these men’s company, it was true that Galileo seemed calmer. He attended to whatever they brought up, clearly relieved at the distraction. And the men were happy to be in his presence. They saw that the moment had finally arrived when one could safely condescend to Galileo. There was a real benevolence in the air as they enjoyed this new pleasure—something like sharing the room with a caged tiger.
But then the nights would come, and sleep would not. Wine did nothing to put him out, nor warm milk neither. Half-crazed he would prowl and howl down the cold moonlit galleries, staring out windows, seemingly confused by the striped duomo of Siena’s cathedral, looming over all the tilted planes of tile. By morning time he would be collapsed somewhere, staring red-eyed at nothing, his voice and mind shattered. It seemed incredible that he could face the day to follow in anything like a coherent form, the night having exhausted rather than refreshed him. And indeed by day there were dark hollows in his face, and his politeness to guests was a brittle thing. One afternoon a Father Pelagi joined the group to give a presentation on whether whirlpools created vortices of attraction or repulsion, and Galileo sat by the window with his arms crossed over his barrel chest, glowering as he listened to this priest’s unexpected mishmash of Aristotle and Scripture. At the assertion that a floating body would sink if the material’s buoyancy was not enough to keep it on the surface, he snorted and said, “I see your whirlpool has pulled in even your argument, it runs in such circles!”
“What do you mean?” Pelagi snapped.
“I mean,” Galileo said, “you make a circular argument. You are saying things float because they want to float. These are not whirlpools, but tautologies.”
“How dare you,” the priest retorted. “You who have been reproved by the Holy Office!”
“So?” Galileo said. “The Earth still moves, and you’re still a fool!” And he leaped to his feet and jumped on the man and started beating him. The others had to haul him off and then get between them. After some shouting and scuffling Pelagi was ejected—indeed, nearly defenestrated. Piccolomini announced that he was banished from the palazzo for the rest of Galileo’s stay. On the other hand it had been good to see the old warrior so feisty again, and everyone hoped it might refresh and reinvigorate him.
But that night the howls from Galileo’s room were more anguished than ever. The moon happened to be full, giving his performance the true lunatic brio. For those who had to endure it, it was like when a baby is crying; an hour seems a year, a night all eternity.
Then the next day some real problems also arrived to disturb him, in news conveyed by one of Maria Celeste’s letters. Galileo’s friends Gino Boccherini and Niccolo Aggiunti had come to San Matteo to ask her for the keys to his house and desk, so that they could enter and remove certain papers. It was during the time we suspected you to be in the greatest danger; they went to your house and did what had to be done, seeming to me at the time well conceived and essential, to avoid some worse disaster that might yet befall you, wherefore I knew not how to refuse them the keys and the freedom to do what they intended, seeing their tremendous zeal in serving your interests.
This action had come on Galileo’s instruction, as he informed Maria Celeste later; he had sent a letter to his friends (ex-students again) requesting their help. So he must have been afraid that the case against him was not yet over. And he was probably right to think that some of the things he had written down through the years might prove dangerous. Copernicanism, atomism, the sun a live creature, something like a god—he had written a lot of things that could worry him now.
Even with those papers in the house spirited away, there were still reasons to fear. It was becoming obvious to us that Urban was still very angry at Galileo. It was possible Urban felt now that Galileo had been let off too lightly—that in order to show resistance to the Borgia, he had not inflicted as much pain on Galileo as he really wanted to. Luxurious house arrest in an admiring archbishop’s palazzo was not much of a punishment for vehement suspicion of heresy. For now, Urban was taking out his anger elsewhere; the news coming to Siena made it clear that all those who had helped Galileo were being punished for it. Riccardi’s prevaricating did not save him; he was dismissed as Master of the Sacred Palace. The inquisitor in Florence who had approved the publication was reprimanded. Castelli had fled from Rome to avoid notice. Ciampoli was ordered to leave Rome, and for life, Urban told everyone. He was going to be a parish priest in one of the miserable villages of Umbria for the rest of his days.
And these were by no means the strictest punishments Urban was ordering, for he was in a truly foul mood. A bishop and two priests accused of conducting black masses to call down his death were tied together to the stake and burned in the Campo di Fiore. People said these unknown miscreants had served Urban as replacements for Galileo, who had somehow slipped away—at least so far. The story was not necessarily over. For the pope was clearly no longer quite sane. So there were real reasons for fear; and sometimes fear took Galileo over. By day he smoldered, he fulminated, he moaned, he roared and shrieked. He stumbled to his bed and failed to sleep. And then at night the fears took over, each one a blacker dark night of the soul.
In this sad disarray the days stumbled along. Piccolomini, at a loss, consulted Cartophilus again. After that he went out to the cathedral’s workshop and asked the artisans what they were working on. From them he learned of a problem they were having in the city foundry, where they were trying to cast a replacement for the cathedral’s largest bell. The casting mold for the new bell was made of two immense blocks of clay, with the outer mold turned upside down and held in position by a framework of heavy beams, and the inner mold, a massive solid plug with its outside carved to the shape of the inside of the bell, suspended from a lattice of cross beams in a position very close to the curved clay of the outer shell. The empty space between the two molds was the shape of the bell. This was the usual method, and all seemed well with it, but when they poured in the molten metal, it ran to the bottom of the open space and pooled there, shoving up the inner mold even though the massive block of clay weighed much more than the poured metal did. No one could understand it.
Piccolomini, walking around the great wooden armature holding the cast, smiled. “This is good,” he said. “This is just what we need.”
He went to Galileo and described what had happened, and Galileo sat and thought about it for a while. For a time it looked as though he had forgotten the matter and slipped into sleep, which even by itself would have been a benefit. Then he stirred. He took up a big sheet of paper and his quill and inkpot, and drew a side elevation of the problem to illustrate his points to the archbishop. “I discovered this when I was working on the floating bodies problem. What I found was that a very small weight of liquid can lift a much greater solid weight, if the liquid is trapped in a curve below the weight, as here.”
