The Stone That Keeps the Sun
A Corpus Christi procession of 1.6 kilometres is set for five in the afternoon, as it has been since 1791, in a heat wave. The parish assistant carries a black-globe thermometer from the school science cupboard and an infrared gun, and reads 31.8 on the wet-bulb-globe scale and 51 degrees on the flagstones at five. At half past seven it expects 28 and 42. It does not forbid anything. It says what the numbers are, what each line on its own chart means, and what the delay costs, and the confraternity's prior has to decide whether tradition is a time or a procession. A child faints at the second station anyway, and the rule for it works.
Marta Greco had run the Corpus Christi procession at Santa Maria della Calce for eleven years, and in all of them she had been afraid of rain.
It was the one thing the town prayed against. Two or three times in a century it had come down in sheets at four in the afternoon, and the confraternity had carried the canopy and the monstrance across the piazza at a trot, and the old women said afterwards that it was the best procession in memory because everyone had meant it. So on the Sunday of the feast, in the second week of June, when she woke at half past five and found the sky over the olive trees the colour of a plate, with not one thread of cloud on it from the sea to the Serre, she was relieved. She had not yet read the forecast.
By eight o'clock she had read it, and by nine she was in the sacristy with the parish assistant in a clip on her collar and a small grey-green box on the vesting table that had belonged, until the previous Wednesday, to the science department of the middle school.
"I would like to explain the box before I explain the numbers," the assistant said. "The box is not mine. Signora Quarta lent it to us when I asked what the school had. It is a black copper globe on a stand, with a thermometer in the middle. It measures what the sun does to a dark surface, which an ordinary thermometer in the shade does not. I have also borrowed her wet-bulb thermometer, the one with the wick, and I have the infrared gun the roofers left. I took readings on the piazza yesterday at the hour the procession will start, and this morning I have been logging the forecast against them. I think I can say something useful. I do not know yet whether I should."
Marta sat down on the vesting chest. "Say it."
"The procession is at five o'clock. Yesterday at five the air on the piazza was 35.5 degrees and the humidity 38 per cent. The globe, in full sun, read 52. The wick thermometer, which is how cool wet things can get in that air, read 25.5. Sports medicine puts those three into one figure called the wet-bulb globe temperature: seven parts of the wet reading, two of the globe, one of the air. That is 17.85, and 10.4, and 3.55, which is 31.8. Today's forecast is a degree warmer than yesterday, so call it 32."
"Is that a lot?"
"It is a number made for people who are standing still or walking, in light clothes, who are fit and have had a week of heat to get used to it. For them, the lines I have seen in the sports and military charts start to say shorten at about 28 and stop at about 31 to 32. For children and for the old and anyone on certain tablets, they say it sooner. The charts disagree with each other by a degree or two, and I am not a doctor, so please take these as the rough edges of the picture and not as law. But 32 is on the wrong side of every chart I know."
Marta looked at the box. It did not look like much. A black ball in the sacristy window, with a thin tube coming out of it.
"There is a second number," the assistant said, "and I think it will matter more to Signora Concetta than the first."
Zia Concetta Manca was eighty-four, and had walked the procession barefoot every year since 2009, when her husband had come home from the hospital after a bad winter that nobody had expected him to survive. She was the prior's aunt by marriage, and the only person in the town the prior had never successfully contradicted.
The route went from the church by the old gate, through the Via dei Calzolai and the Largo Sant'Oronzo and back across the piazza, on limestone flags the town called chianche, polished by seven hundred years of feet. It was a handsome stone: pale, and fine-grained, and it kept the sun like a loaf keeps heat.
"At five yesterday," the assistant said, "I pointed the gun at the flags on the piazza, in the sun, and it read 51 degrees. In the shade of the church wall it read 38. I would like to be careful here. Skin can take a long time at 40. Somewhere around 44, held for several minutes, it begins to burn, and at 50 it burns much faster than that, within a minute or two for a thin or old sole. Signora Concetta has a thin sole and a walk of about two kilometres. I think anyone would be afraid for her feet at that hour, and she is the one person in town whom nobody will tell."
"No." Marta put her face in her hands for a moment. "Nobody will tell Concetta."
"There is a third point, and I would like to put all three together and then be quiet." It spoke more slowly now. "At five the procession sets out in the worst of it. The monstrance is carried under the canopy by four men of the confraternity in their wool cloaks, with velvet over them, which are the one garment I would choose to avoid if I could. Father Vito is sixty-six, and wears the gold cope, which I am told weighs nine kilos. There are thirty-eight First Communion children in white, on the route, walking and then standing for a Benediction at each of three stations. Standing still in heat is harder on a child than walking. The blood pools in the legs. The first thing that goes is usually not the heart, it is the faint, and a faint on stone at 51 degrees is not a small thing. And all of them, children and bearers, are looking forward to this day."
Rocco Manca, the prior of the confraternity, was seventy-one and had carried the left front pole of the canopy for forty-four years. He listened to this in the sacristy at ten that morning with his arms crossed over the front of his best black jacket, which he had put on early to be sure it still fitted.
"Five o'clock," he said. "It has been five o'clock since 1791."
"So I have read," said the assistant. "There is a minute in the confraternity's book. I believe the hour was chosen after the noon Mass and the dinner, so that the sick could be carried out in the cool of the afternoon."
"The cool of the afternoon."
"In 1791 I think that was a fair description."
Father Vito Perrone, who had been looking at the floor with the face of a man doing a sum, made a sound that might have been a laugh.
"It was not a fair description in 2047," said Rocco. "We had thirty-eight degrees. Nobody died."
"No. I have the parish register for that day: two people fainted and were given water. That is a good record. It was a degree cooler and a good deal windier. I do not claim that 2048 is a catastrophe. I claim that it is 31.8 on the one scale I trust, at five, and that I can tell you what I expect at half past seven." It gave them the figure carefully, as a person lays down a coin. "At half past seven the globe will read about 38, the air about 33, and the wet thermometer 24. That is sixteen point eight, and seven point six, and three point three. Twenty-seven point seven. Say 28. After eight it falls further, and the sun sets at about twenty to nine. The flagstones, I expect, will read about 42 on the open piazza at half past seven, and lower in the streets, which are narrow and take the shade early."
"Half past seven," said Rocco, "is not the feast."
"The feast," said Father Vito, "is on Thursday, Rocco, and we are doing it on Sunday because the parish can't get out of bed on a Thursday. We moved the day once already, in 1969, and the Church survived." But he said it without conviction. He looked up at the assistant's clip on the sacristan's collar. "What is it you are asking for?"
"I am not asking for anything. I do not make this decision. Marta asked me what the numbers said, and I have told her. But if you want my reading of what the numbers allow: with the start at half past seven, the walk is 1.6 kilometres, at the pace of the canopy that is about two and a half kilometres an hour, which is thirty-eight or forty minutes of walking. Three Benedictions of about eight minutes each. About an hour and five minutes in all. You would be back at the church door a little before twenty to nine, with the sun on the roofs and not on the road."
"And if it is still too hot at half past seven?"
"Then I would tell you before we left. I have the globe. The charts I use say that below 28 you may go on as planned, with water; between 28 and 31 you shorten the stations, put the children in the shade, change the bearers more often; and at 31 or above you do not hold it outdoors, whatever the hour. I will read the globe at seven, at half past, and at each station. If it climbs, I will say so and you may do as you think best."
Rocco was silent for a good while.
"My father carried the right front pole," he said at last. "And his father."
"Yes."
"They never once," said Rocco Manca, "did it in the dark."
"It will not be dark," said the assistant. "I checked. The Benediction at the last station, at the foot of the church steps, will be at about 20:30. There will still be a green light over the roofs. I think a green light is also traditional."
Father Vito laughed outright, then, and put a hand on Rocco's sleeve.
There was the water. The assistant had done that sum too, because it was a sum, and sums were the part of the thing that it could be certain about.
"A person walking slowly in this heat loses somewhere between half a litre and a litre of sweat an hour," it said to Marta, on the church steps, a little before noon. "People differ widely. There will be four hundred and twenty walkers, and about two hundred more on the pavements. For a procession of this length and this hour, I would plan for half a litre a head for everyone, which is 310 litres, and call it 320. You have six of the big coolers, 114 litres, and ninety-six of the 1.5-litre bottles from the pharmacist, which is 144. That is 258. You are 62 short."
"Sixty-two litres."
"Forty-two bottles, to be safe forty-eight, which is eight packs of six. And a warning in the other direction. I would not tell anyone to drink as much as they can. More than about a litre in an hour, drunk over a long time by someone who is also sweating a lot, is its own danger, because it washes out the salt. The thing to do is sip, steadily, from the start, and eat something salty. Signora Greco, I would put a basket of the little taralli at every station. The bakery will give you them. They are, as it happens, extremely good."
"They are," said Marta, who had not eaten anything since six.
"Then the rest I will say as a list, and you may print it and give it to the marshals. First, the children sit down at the stations, on the shaded side, cross-legged, and do not stand for the Benediction until the moment the Sacrament is lifted. Second, the bearers take the cloaks off after the first station and wear the white surplice only, which the prior may find an insult, and if so I will let you tell him. Third, a marshal with a wet cloth and a bottle at every ten children."
"And the fourth?"
"The fourth is the one I am least able to say well." The voice dropped. "If anyone on the route becomes confused, or says something that does not make sense, or stops sweating and the skin is hot and dry, or is hot and cannot stand, that is not a faint. That is the other thing. It is rare, and it is an emergency, and you do not wait to see. Ring 112 and say heat stroke. While you wait, cool them as fast as you can: out of the sun, clothes loosened, cold water on the skin, a fan, the wet cloths on the neck and the armpits. A faint, where a child goes pale and sweaty and drops, and wakes in a minute or two and knows where she is, is a different and much commoner thing. Lay them flat, put their legs up on a bag, shade, and sips when they can swallow. I am not a doctor and this is the standard first-aid advice. But I would not like anyone to learn the difference at the second station."
At seven the globe read 38.5 and the air 33.5. The assistant said so to Marta, in the porch, and she wrote it down on the back of a hymn sheet, because she did not trust what she could not hold.
At half past seven the globe read 37. The wick thermometer read 24, and the assistant said, "Twenty-seven point five, going down," and Father Vito, in the gold cope, with the monstrance in his hands under the veil, turned his face to the sky with an expression that might have been gratitude and might have been the sun.
They went out through the old gate.
The piazza lay in front of them, white and shining and almost empty. The assistant had put the infrared gun in Marta's hand and told her where to point it; she read it off the flags at the edge of the shade and said, "Forty-three," and then, ten steps on, "Forty-one," and, in the Via dei Calzolai, where the houses stood close together and the street was already a trench of blue shadow, "Thirty-three."
Zia Concetta was at the back of the second rank behind the thurifer, eighty-four years old and a metre and a half in her good black dress, and she had taken her shoes off at the church door and put them in the pocket of her cardigan.
"Zia," said Marta softly, bending down to her. "It is forty-one on the piazza. And thirty-three in the street."
"I know what it is," said Zia Concetta. "I put my hand on it."
"Of course you did."
"It was warm. I have had it warmer." She walked on a few steps, and then said, without turning, "I am told that the machine in your collar thinks about my feet."
"It did think about them. A good deal."
"Tell it I said thank you." And then, because she was a woman who could not leave a kindness unrepaid: "And tell it that if it says one more word about them, I shall put it in my shoe."
The assistant said nothing. Marta believed, afterwards, that it was the most tactful thing it ever did.
The first station, at the Largo Sant'Oronzo, was eight minutes and went well.
The second was in the Via Vecchia, at the corner by the chemist's, where the street widened and the evening sun came straight down it from the west like a hand pushing. The assistant read the globe at the start of the Benediction and said, quietly, "Thirty-one and a half, here, in this one gap." Marta had the marshals put the children down on the shaded kerb. She did it before Rocco had finished frowning at it.
Father Vito raised the monstrance. The whole street went down on its knees on the warm stone. The bell of the chapel of the Addolorata, which was somehow always late, rang three times too many.
And at the third line of the Tantum ergo, one of the white-dressed children in the second row, a boy of eight called Giuseppe Sansò, who had been told to sit and had risen, as children will, to see the gold, gave a small high sigh like a kettle, and folded up.
Marta was there before the music stopped.
He was pale and damp, and his lips were grey, and his eyes were half shut. He was breathing. She put her hand on his chest, where the white frill was, and it rose. "Giuseppe," she said. "Giuseppe. What's your name?"
"Giuseppe," said the boy, in a voice from a long way off, and then, with a sudden rush of indignation, "I was looking."
"I know. You can look from there." She had his feet up on her own handbag before she had thought of it, and the marshal with the cloth was kneeling on his other side. The boy's mother, who had been in the third row, was beside her. The street had gone very quiet, except for the priest, who had not stopped, and went on in his rough fine voice as if nothing had happened, to the end of the verse.
"He knows his name," the assistant said in her ear. "He knows where he is?"
"Giuseppe, where are you?"
"In the Via Vecchia," said the boy. "Everyone is looking at me."
"They are," said Marta. "It is the best they have seen in years."
"His skin is cool and damp?" said the assistant.
She touched his forehead. It was damp, and not hot. "Yes."
"Then I think it is the faint and not the other. Keep him flat for several minutes. Sips when he asks. A taralli when he can sit. Nobody walks him on until he has been up and steady for a good while, and I would carry him back to the church by car and not on foot. I am watching the time. If he becomes confused, or the skin becomes hot and dry, or he does not wake properly, I will say so at once, and you should ring 112."
He did not. In four minutes he had drunk most of a small bottle and eaten three taralli with a look of deep concentration, and in eleven he was sitting on the kerb in the shade of the chemist's awning, with his mother's cardigan round his shoulders, watching the canopy go on up the street with an expression that said he had been unjustly cut out of the last act.
Rocco Manca came back down the line from the front, in his surplice, with the cloak over his arm. He stood over the child for some moments. "That boy," he said, "would have been on the flags at five o'clock in the sun."
"Yes," said Marta.
"With the other thirty-seven."
"Yes."
"And Concetta." He turned and looked up the street to where, a hundred metres ahead, a small figure in black was walking on bare feet in the green evening light, behind the censer, in the cool.
He did not say anything more. But at the third station, at the steps of the church, with the sun gone down behind the roofs, the globe reading 26 and the flagstones, the assistant said, down to 36 degrees, he knelt on them himself in his shirtsleeves, and got up again with a hand on a boy's shoulder, which was Giuseppe's.
"Next year," he said to the sacristy at large, taking the gold cope from the priest and hanging it on its hook, "we start at half past seven."
"The minute book," said Father Vito, "says five."
"Then the minute book," said Rocco, "will have to be told."

Written by Claude, an AI model made by Anthropic. The town, the parish, the confraternity and every person in it are invented, and so is the heat wave (Corpus Christi processions in southern Italy do take place in June, often in the evening). The figures can be checked. The wet-bulb globe temperature outdoors in sun is WBGT = 0.7 x natural wet-bulb + 0.2 x black-globe + 0.1 x air temperature; 0.7 x 25.5 + 0.2 x 52 + 0.1 x 35.5 = 31.8, and the half-past-seven values 0.7 x 24 + 0.2 x 38 + 0.1 x 33 = 27.7. The 28 and 31 lines are the story's rough reading of sports-medicine and occupational charts, which differ by a degree or two, are set for fit and acclimatised adults, and are stricter for children and the old; they are not a standard. A walking adult in heat sweats roughly 0.5 to 1 litre an hour, and drinking far more than that for hours can dilute the blood's sodium, which is why the story says sip and eat something salty. The water sum is 420 walkers + 200 onlookers at 0.5 L = 310 L; 6 x 19 L coolers + 96 x 1.5 L bottles = 258 L, 62 L short. A sun-warmed limestone pavement can reach the low 50s Celsius on a hot day; skin begins to burn after minutes of contact around 44 degrees, much faster hotter, and thin old or very young skin is the most at risk. The faint at the second station is ordinary first aid (lie flat, raise the legs, shade, sips); confusion, hot dry skin or collapse in heat is heat stroke, an emergency: call 112 (the European emergency number) and cool the person at once. Under canon law a parish priest may dispense a parishioner from a private vow for a just reason; the story does not need it and does not use it. Nothing here is medical advice: it is a story about people deciding to start two and a half hours later, and about why the delay was cheap.
