The River Is Eight Degrees

Science fiction about what might be · Sainte-Colombe-des-Gués, an invented village on an invented river, the Lisse, in the French Jura, Holy Saturday 13 April 2047 · 16 min read · Written by Claude (AI) · CC BY-SA 4.0

A parish has baptised its catechumens in the river at the Easter Vigil since 1998. Snowmelt makes the water 8 degrees and the current faster than the practice runs allowed, and one candidate is seventy-one with a heart that fibrillates. The parish assistant sets out the cold-shock clocks, a depth-times-speed number for the wading, and the time each person spends in the water; the priest reminds everyone that the Church baptises by pouring as validly as by immersion; and the candidate, not the assistant, chooses.

Hélène Perrin had waited sixty-one years to be baptised, and she was not going to be told by a speaker on a church wall that she could not do it in the river.

"I did not say that," said Passeur.

It was the parish assistant, named by the children in 2044 for the old man who had once taken people across the Lisse in a flat boat, and it spoke from the sacristy of Sainte-Colombe-des-Gués, from the little grille above the vestment press. It had asked Hélène to come in on the Thursday before Easter with her husband's cardigan over her arm and her pills in her bag, and she had come, and now she sat very straight on the sacristan's chair with her chin up.

"You said the river was eight degrees."

"I said that the river is eight degrees, which is what the gauge below the weir reads this morning, and that on Saturday night it will be between seven and nine, because the snow is going off the Risoux and nothing warms it. I said that you have atrial fibrillation, which you told me yourself in March when you asked whether it mattered for the catechumenate. And I said that I would like to put some numbers in front of you, and in front of Père Aurélien, and in front of your doctor if you will let me send them. I have not said you cannot go in. I do not decide that."

"Who does?"

"You do. And the priest, for the part that is his."

Père Aurélien, who had been standing by the vestment press with a surplice over his arm, said nothing, but the surplice moved slightly, which in him was a sign of attention.


The practice was older than anyone in the room under fifty. In 1998 the bishop had given the parish leave, for the one night of the year, to begin the Easter Vigil on the gravel bar below the bridge: the fire, the candle, the readings, the blessing of the water, and then the baptisms, in the river, by the light of the candle and four floodlamps on stands. It had been a bold thing to ask for. It had also been August-warm that first year, by accident of the calendar. The water had not been under thirteen degrees since 2011, but the Easter of 2047 was the fourteenth of April, early enough for the snow to still be coming down off the mountain, and there were six to be baptised.

"I have been through the Vigil of the last nine years," said Passeur. "I have the river temperature for each from the weir gauge, and the air at the bar from the weather post at the sawmill. In nine years it has been under ten degrees four times. It is eight this year, and the air will be around four at nine o'clock and fall toward two. I do not have a reason to cancel anything. I have three clocks, and I want you to hear them in order."

"Clocks," said Hélène.

"The first is the one every cold-water rescue course teaches. It has a name, and it is a rule of thumb, not a law of physics. One minute, ten minutes, one hour." The voice was dry and unhurried. "When a person goes suddenly into water below about fifteen degrees, the first minute is the cold shock. The skin senses the cold, the breath comes in as a gasp you cannot stop, then fast and shallow, and the heart rate and blood pressure jump. It peaks in the first thirty seconds or so and settles by about three minutes. For most people that is a bad minute and nothing more. If the head goes under in that minute, the gasp is the danger. If the heart is already prone to an irregular rhythm, the jump is.

"The second clock is ten minutes. Over about ten minutes in cold water the muscles of the hands and legs lose their grip and their strength. That is not hypothermia. It is the arms and legs not doing as they are told. The third is one hour, and nobody here will be in the water for an hour, and I mention it only so you know that it is not what I am worried about."

"And I am the first clock," said Hélène.

"You are the first clock, with a heart that has an irregular rhythm and an anticoagulant that your doctor prescribed so that a clot will not form in it. The cold shock does not make a clot, and it does not touch the anticoagulant. What it does is make the atria beat harder and faster for a minute or two, and I cannot tell you what yours will do. Neither can Dr Okonkwo, honestly; she told me so on the telephone this morning, and she gave me leave to repeat it. I know what your resting heart rate is. On Tuesday you let me measure, with the hospital's clip on your finger, a foot held in an eight-degree bucket for sixty seconds. Seventy-eight at rest. One hundred and eighteen at the end of the minute, irregular. A hundred and four at three minutes, still irregular, as it usually is for you. Then back to the old rhythm in about ten more."

"A foot," said Hélène. "Not the whole of me. Not my head."

"A foot, yes. Which is why I do not think it tells us less than the whole river would. I think it tells us a good deal of what the first minute would be, and it was not alarming. It was not reassuring either. One test, one woman, one morning. I cannot turn that into a promise."


The second clock was a different one, and it was for everyone, and Passeur laid it out on the sacristy table on a sheet of the parish's graph paper, in a column.

There were six candidates, a priest, a deacon, six sponsors and two volunteer firemen on a safety line. A baptism in the river, as the parish did it, went like this: the priest wades to the pool below the bar, thigh-deep, and the candidate comes in with the sponsor, steps down to the same depth, and is baptised, and walks out into a blanket. Thirty seconds to wade in. About a minute for the rite, with the three pourings or immersions and the words. Thirty to get out. Two minutes a candidate in the water, for the candidate and the sponsor. Twelve minutes for the priest, who is in the water for all six.

"It is the twelve I was thinking of," said Passeur. "Not your two. Water takes heat from the skin about twenty-five times as fast as air at the same temperature. The priest will be standing in a pool of eight degrees for twelve minutes in waders that are insulated but are not a drysuit, and in the middle of that ten-minute clock. His hands go first, by minute eight or nine, and then he is holding a candle, a shell and a book. I would not like to have the Church's most important night of the year dependent on whether the fingers of one man still close."

"I can last twelve minutes," said Père Aurélien, mildly.

"Probably you can. I would like it to be eight. I suggest that Deacon Marc takes the last two candidates and you take the first four. Eight minutes for you, four for him. And nobody in the water for more than ten, whoever they are, without a break."

"And the current?"

It was the deacon's question, and it was a good one. He had not spoken yet. He was a retired engineer from the cheese co-operative, with a gentle stoop and the hands of a man who has put in a good many fence posts.

"I am glad you asked," said Passeur. "The third clock is not a clock. It is a product. The depth of the water in metres multiplied by its speed in metres a second is a rough guide to when an adult is in trouble standing in a river. Below about a third, most adults stand easily. Above about six tenths, they are in difficulty, even good swimmers. Between, it depends on the bed, the footwear, the person and whether they have been in cold water for ten minutes. It is a guide, not a standard.

"Last year at this pool the depth was 0.7 metres and the speed 0.3. That is 0.21, well under the line. This year the snow is coming off, and I measured it at the bar on Wednesday with a float and a stopwatch: 0.9 metres deep at the place where the priest has always stood, and a surface speed of 0.6 metres a second. Surface speed is faster than the mean speed through the water, so using it overstates the risk, and I mean to; the product is 0.54. That is nearly at the top of the middle band. It is a number for a man in waders standing on gravel in the dark, with a woman of seventy-one on his arm.

"If the pool is moved thirty metres down, to the shallow beside the old ferry landing, the depth is 0.55 metres and the speed 0.35 at the surface. That gives about 0.19. That is wading in a pool, not in a river. I am asking that the place be moved to the landing."

"The landing is in the lee of the wall," said the deacon. "There is no gravel bar. The ground is mud."

"Yes. There is a landing stage of oak planks that the fishing club maintains, three steps down into the water and a rail. I have walked the planks. A person who is cold and wet cannot be asked to find her feet on mud. She can walk down three steps."


Père Aurélien set the surplice on the press.

"I will say something," he said, "which is not a number, and is in the book."

He turned to Hélène and spoke directly to her, not to the grille.

"The Church baptises by washing with water, in the name of the Father and of the Son and of the Holy Spirit. It does that either by immersion or by pouring. Both are the sacrament, and neither is a second-best. Pouring water three times on the head is baptism entire. It is what I do for a baby in the church, and what I would do for you in the hospital if I were called to you in the night. I want you to hear it from me and not only from the machine. You will not be less baptised if you do not go under. You will be wholly baptised."

"I know that," said Hélène. "I read the Catechism. I read all of it, in March, with a highlighter."

"Then you know it, and I am not teaching you."

"No. You are making it easy for me to say no." Her voice shook a very little, on the last word, and she steadied it. "Père, do you know why I wanted the river?"

"Your husband."

"My husband Gérard went into the Lisse in 1998, the first year, in August, at the foot of the bar, because I would not. I stood on the bank in a good dress, a Protestant from Montbéliard, with my arms folded. He was baptised and I was cross. He said I would come in when I was ready. He is nine years dead, and I am ready, and the river is eight degrees."

Nobody said anything.

"Passeur," she said at last.

"Madame."

"If I went in to the knees. To the knees only, on the planks, and Père poured the water on my head from the shell, three times, with my husband's cardigan on my shoulders. Is that the river?"

"That is a question of meaning, and I don't answer it."

"Then I'll answer it. Yes." She breathed. "What would the numbers say?"

"The numbers I can give you. Knees deep is about 0.4 metres: on the landing, with the speed we have, a product under 0.15 (0.4 times 0.35 is 0.14), which is no trouble. The water on your head, from the shell, comes from the font that has been blessed, which is river water and would be at about eight degrees. A shell of it on your head is a smaller and slower cold than going in whole, because your face and neck are not suddenly under it, and you will be standing. I do not know that it will be gentle on the heart. I think it is likely to be much gentler. I cannot say that it is safe, and I'd like to put two things around it, because I would put them around anyone."

"Which are?"

"That you rest before it, warm. Dr Okonkwo has asked that you sit in the church with a hot water bottle until the third reading, and not stand in the cold for the fire. And that the nurse of the fire brigade sits within arm's reach on the landing with her bag and the monitor, and that you have an agreed signal to stop. And that you know now what you will do if the beat goes wrong: you say so, the priest stops, and you are carried in out of the cold and a call is made. That is not me deciding for you. It is the shape of a plan that is yours."


They went through the rest in the hour after that: the six blankets, warmed in the sacristy oven at its lowest setting until Passeur noticed the paper tag on one and had the sacristan take it out; the two tents for changing, with a hot-water urn in each; a rule, written on the back of the graph paper, which the deacon copied out fair and the sacristan pinned to the door. Nobody in the water more than ten minutes in all. The priest hands the shell to the deacon after the fourth. Anyone who cannot close a hand is out, and does not argue. The Vigil goes on without them.

At the bottom, in the deacon's square engineer's capitals, he had added one line the machine had not suggested: Nobody is cross.

On Holy Saturday it rained until five, and then it stopped, and at nine the fire on the landing was lit and caught, and the candle was carried down the three planked steps in the dark, and the readings were read by the light of the four lamps, with the river going by black and loud on the left. Passeur read the water on the gauge to the deacon through the ear-piece, as agreed, at the start and at every candidate: eight point one, eight point one, eight point three. The air was three and a half.

The first four went in to the thigh, one after the other, with their sponsors. A girl of seventeen, Léa, gasped so loudly at the first step that the firemen laughed, and she laughed too, and was baptised laughing, and came out in her blanket pink as a ham. A big farmer, forty, who had come to it through his wife and a bad year, went in without a sound and came out with tears on his face, which could have been the river.

Père Aurélien's fingers closed on the shell for all four. At the end of the fourth he handed it to Deacon Marc, as he had agreed in the sacristy, and stepped out of the water, and stamped his feet, and found the deacon giving him a look he knew from the altar boys.

Hélène went fifth. She had sat for three hours in the church with a hot-water bottle in the lap of her good dress and had said nothing to anybody, and a nurse of the fire brigade, Odile, in a red jacket and a woollen hat, took her arm at the top of the planks and went down with her to the second step, and stood. The water came to a hand's breadth above the knee.

Hélène stood in it a moment. Her mouth opened. A short, sharp breath went in, the gasp that the machine had named, and the deacon's hand on the shell did not move, and Odile's thumb lay on the inside of her wrist.

"Madame?" said the deacon.

"Go on," said Hélène, in a high clear voice. "It is cold."

He poured. The shell held a third of a litre, and it ran down her forehead into her eyes and collar, once, twice, three times, and the words went over it.

She came up the planks on Odile's arm in Gérard's cardigan, wet through the collar, and Odile did not take the thumb away until the top of the stair, and then said in her ordinary voice that it had been irregular and not fast, a hundred and ten at the start and ninety by the second pour, and would madame please go into the tent. Hélène said she would, and presently she did.

The sixth went in, a lad of nineteen who had to be told not to run.

At a quarter to eleven the Vigil moved up to the church by torchlight for the Eucharist, with six wet people in blankets in the front pew, and a seventh, in a red jacket, at the back with her bag on her knee. In the sacristy afterwards the sacristan fed the log into the book, as he always did. Six baptised. No one out of the water more than nine minutes. Priest eight, deacon four. Gauge 8.3 at the end. Nobody was cross.


Passeur had one thing left to say, and it said it at half past one in the morning, when the church was dark and the only light was the red lamp, and Père Aurélien had come back for his keys.

"Father."

"Yes."

"You will want to know whether I would do it again."

"I thought you would tell me."

"I think that the numbers on the sheet were fair. The place was better at the landing than the bar, by a product of 0.19 against 0.54, and I'd say that again. The twelve minutes would have been a risk, and eight was not. The cold shock was a real gasp in a woman with an irregular beat, and it did what it did for ninety seconds, and it did not do worse. I do not know that it would not have done worse in someone else. I told her that, and it is still true. It was her choice, and she was right to make it, and it would have been her choice if she had made a different one.

"I will say one more thing, which is not a number. At the bottom of the sheet you have a line that I did not write."

"Marc's."

"Yes. I should like to keep it."

The priest took his keys from the hook, and looked for a while at the red lamp, and then at the grille, which was just a grille.

"Keep it," he said.

This story was written by an AI and is fiction. Sainte-Colombe-des-Gués, the Lisse, the Risoux crossing as a source of snowmelt, the landing stage, the parish, its people and the assistant are invented (the Risoux is a real forest massif in the Jura; the Lisse is not a real river), and so are the bishop's 1998 permission and the practice of baptising in the river at the Vigil. The Church does teach that baptism is validly given by immersion or by pouring water on the head with the Trinitarian formula (Catechism of the Catholic Church, 1214; the Rite of Christian Initiation of Adults allows both); bishops' conferences and local liturgical law govern where the Easter Vigil is celebrated, so a real parish would ask its own bishop. Easter 2047 falls on 14 April. The cold-water figures are rules of thumb, not standards: the "1-10-1" principle (about one minute of cold shock, about ten minutes of useful movement, about one hour to hypothermia, with large individual variation) is taught in cold-water safety courses; water carries heat from skin away about 25 times faster than air at the same temperature, a commonly quoted round figure. The wading guide (depth in metres times velocity in metres a second, with roughly 0.3 as comfortable and 0.6 as difficult for adults) is a rule of thumb used in river-crossing and flood-safety guidance, with large variation by bed, footwear and person. The story uses the measured surface speed, not the lower mean speed, which is the conservative reading: 0.9 m x 0.6 m/s = 0.54 at the bar; 0.55 m x 0.35 m/s = 0.19 at the landing; knee-deep at the landing, 0.4 m x 0.35 m/s = 0.14. Twelve minutes for the priest is six candidates at two minutes each; eight and four after the swap. The heart-rate readings and the foot test are invented, and one test on one person proves nothing about anyone else. Apixaban is not named; the story says only an anticoagulant. This is not medical or safety advice. If you have a heart condition, ask your doctor before any cold-water immersion, and never swim or wade in a river in spate alone.
