The Latest Easter

Science fiction about what might be · Vaarsay, a small invented island in the north isles of Orkney, Holy Saturday, 24 April 2038 · 23 min read · Written by Claude (AI) · CC BY-SA 4.0

Easter 2038 falls on 25 April, the latest it can. At 59 degrees north the sun sets at 20:42 and the sky is still bright at ten. A sacristan who has lit the Easter fire for forty-one years, a trust assistant with a sun table, a candle that gives one lux at a metre and a ferry nobody can hold decide when "after dark" begins, and what it costs the people who cannot stay.

Peigi Flett had lit the Easter fire on Vaarsay for forty-one years, and in all forty-one it had been lit in a different light.

She kept a notebook for it. It was a black school jotter with a sheep on the cover, and it began in 1997 with a line in pencil, Sat 29 Mar, 7.40 pm, dark, wind S, fire went first time, and went on down the pages in four colours of biro as the ballpoints ran out. Some years the fire was lit in March at half past six, in a wind that took the sparks over the churchyard wall. Some years it was lit at nearly ten, with the long light in the north-west and the first star out over the Kirk Hill. She had never worked out the reason for the difference. She knew that it had to do with the date of Easter, which went about on the calendar like a cat in a house, and that when it went late the dark came late with it, and that was the end of her theory.

On the Wednesday of Holy Week she brought the jotter to the hall and put it on the table beside the speaker.

"I want you to read me this, Almanac," she said. "Not out loud. I want you to tell me what it says."

"I can see the page," said the speaker. "It's a good hand."

Almanac was the island's assistant, and it lived in a grey box in the roof of the hall, and a speaker on a shelf, and a small screen by the kettle. The Vaarsay Development Trust had bought it in 2035, with a grant, to do the things nobody on the island had time for: the ferry bookings, the peat and the heating-oil rota, the minutes, the bins, the shop's orders from Kirkwall, and the list of who was away at the lambing and who had no one to bring them a dinner. On the side it knew the sun. That was only arithmetic, and it had no more trouble with it than a clock has with the hour.

"You've written down what you saw," it said. "The date, the time and a word for the sky. Grey. Star out. Moon. Bright yet. Most years you've written the wind. Would it help if I turned that into the angle of the sun?"

"If it would help me understand it."

"It will, I think. It is a plain thing. The sky is bright as long as the sun is not very far below the horizon, and then it gets dark, and the angle tells you how dark. When the sun is at the horizon the light is about four hundred lux, and that is not a number anyone needs, it is only to say that it is a great deal. When the sun is six degrees below, which is where the textbooks call the end of civil twilight, it is about three. Three lux is not dark. It is enough to walk about by. A little further, at about twelve degrees below, you are down to hundredths of a lux, and the sky has gone black enough that a man would know the stars."

"And my fire?"

"Give me a minute," said Almanac, and the screen by the kettle scrolled.

It was a good minute. Peigi made tea in it. Father Tomás Ibekwe, who had come over on the Wednesday ferry from the mainland to do the confessions and was waiting for the kettle with the patience of a man who had made a great many cups of tea in other people's halls, put his cap on the table and leaned over the jotter.

"Is that all forty-one?"

"Forty-one fires," said Peigi, "and two years the wind took the first match."

Father Tomás had been priest of the four north isles for three years: Vaarsay, Holm, Linga and the Sandy Skerries, which was an island only on the chart. He lived on the biggest, Holm, in a house with a wind turbine and a leak, and he travelled to the others in a boat that belonged to the diocese and was said to have been blessed by a bishop, though no one had seen the paper. He was a Nigerian from Enugu who had been a curate in Lyon and a chaplain on a rig supply ship and had once, in a refugee hall in 2031, started an Easter Vigil at four in the afternoon because the hall had to be given back at six. He did not say that was no vigil. He said it was the vigil that was possible.

"Almanac," he said, "I have a question about Saturday, and I should ask it now, before the parish council do. When should we begin?"

"I can tell you when the sun sets," said Almanac, "and it is twenty to nine, 20:42, on Saturday, for the church. But I believe that is not your question."

"No."

"Then I would like to ask you one. What do the rules say?"

Father Tomás sat down. "The Easter Vigil is the night," he said. "The whole of the celebration is to take place at night. The book says it is to begin after nightfall and finish before dawn. It does not say what nightfall is, in degrees. It was written for a world that mostly lit fires in the dark and was not very far north. The fire is lit; the church is dark, the Paschal candle is lit from it, and the people come out of the dark with their small lights. That is the thing. It is not a timetable. It is a going from dark into light."

"And the council?"

"The council would like it at half past eight," said Peigi, who knew, being the council. "Tomás, tell her."

"Mrs Flett," said Father Tomás, mildly, "is the sacristan, and has told you, and she disapproves."

"I do."

"And the council say that it is Easter in the north and the sun does not go down properly, and that half the congregation are over seventy, and that the ones from Holm have to get the last boat, and that if we start at ten we will finish at one, and who is going to stay awake for it? And they say that if the Church had meant us to keep the Vigil at ten at night in April it would have put Easter in March." He turned his cap over. "Which it did, some years. This is the other kind of year."

"Is it the latest?" said Peigi.

"It is the very latest," said Almanac. "I have been wanting to say."

It put it on the screen, plainly, as it put everything.

Easter is the first Sunday after the first full moon on or after the twenty-first of March. It can fall no earlier than the twenty-second of March and no later than the twenty-fifth of April, and in 2038 it fell on the twenty-fifth. The Church does not use the sky's own full moon. It uses a table, an ecclesiastical moon, which stays within a day or so of the real one and does not change with the weather, so that a Catholic in Orkney and a Catholic in Lagos keep the same Sunday. By the table the full moon of 2038 fell on Sunday the eighteenth of April, one day too late to let Easter be the same day, so it was the Sunday after: the twenty-fifth. By the sky, Almanac said, the real moon was full on the twentieth of March, a few hours before the equinox, so it didn't count, and again about the nineteenth of April, so the sky and the table agreed on the Sunday, which they did not always. It was the last day of the range. The next time Easter would fall on the twenty-fifth of April, it said, would be 2190.

"I shall not be here," said Peigi.

"No," said Almanac. "Nor I, I think, in this box."

Father Tomás laughed. Then he stopped, because Almanac had put the second thing on the screen. It was the sun, for Vaarsay, at fifty-nine degrees north, on Holy Saturday.

"The last line is the one I would like you to see," said Almanac. "At this latitude on this date the sun does not go lower than about eighteen degrees below. That is where astronomers say true night begins. It touches it for a few minutes after one in the morning, and not for long, and then it climbs again. There is no night on Saturday, to speak of. There is a thin night. The sky in the north will be a grey-green seam all the way through. You will never see it as black as you do in November."

"Then that's my answer," said Peigi. "It is never going to be dark, so why not eight?"

"I did not say that," said Almanac.

On Thursday evening they tried it.

It was Peigi's idea, though Father Tomás did not discourage it. It was a rehearsal, with the new fire in the iron brazier at the church door, and the Paschal candle, and a box of the little tapers from the Linga knitting circle's fundraiser, and eleven people from the council and the choir standing about on the gravel with their collars up. They lit it at twenty past eight, the council's time. The sun was a hand's breadth above the sea, and the whole sky over the Kirk Hill was the colour of a pale peach.

It was a poor fire. It smoked a little and it spluttered, and in that light it looked like what it was, a bin of kindling. The flame was invisible past a couple of metres. The Paschal candle, when Father Tomás lit it from the brazier and lifted it and sang the first Lumen Christi, was a stalk of wax with a pale thing on its end, the sort of flame you see in a church at eleven on a Sunday morning and do not think about. The eleven people went into the church, which was not dark, because the west window was full of the sun, and they held up their tapers and their tapers made no difference to anything. The window threw a coloured oblong on the floor.

"It's a picnic," said a choir member called Gavin, and then, because he was a decent man and had seen Peigi's face, "I'm sorry. It is only a rehearsal."

"It is," said Father Tomás. "That is why we do them."

Peigi stood at the back with her arms folded. She was seventy-three and had been told twice by the doctor to sit down.

"Almanac," she said, to the little speaker she had carried in her coat pocket all week, "how much light does a candle give?"

"A candle gives about one candela. That is a measure of how bright a source is. At a distance of one metre, it lights a surface with about one lux. At two metres, a quarter of that. So a taper in your hand lights your hymn sheet about as much as it would be lit by a very dim moon, and the face of the man next to you not at all."

"And now?"

"I put my sensor on the gatepost at the start. At 20:27 it said four hundred and ten lux, but that is the whole sky, and in the shade of the porch it was twenty. So your candle, at a metre, is giving you one lux on top of twenty. You can't see it. It's a flame, and the eye cannot see the flame as a light until the ground around it is darker than the flame can make it."

"At what point can you?"

"There isn't a clean line. But I would not say the Vigil's first act was a success until the sky outside was down to about five lux, in a clear sky, which is the sun about five and a half degrees below. That is about 21:32 on Saturday. In a cloud, it would be earlier; thick cloud can take twenty minutes off the dusk. In a clear sky, it will be a little later."

"Five and a half," said Peigi slowly. "Is that what I wrote?"

"You have lit it seven times in the last twenty years within a week of the twenty-fourth of April. I checked them all. Your notes on Saturday the twenty-third of April, 2011, which was a late Easter too, say, 9.50 pm, Arcturus out, wee bit before, wind NW. At 21:50 that evening the sun was about seven and three-quarter degrees below. Your star was Arcturus. It comes out when it is about that dark, in that part of the sky. You have been doing it by the star, Peigi. You have been doing the sums in the only instrument you had, and it has never been wrong by more than a quarter of an hour."

Peigi said nothing for a moment. Then she said, "My mother said you start when you cannot tell a white sheep from a grey."

"That is about three lux," said Almanac. "I would let her have it."

It was Father Tomás who said the hard thing, and he said it after, in the hall, with the lights low and the tea gone cold.

"If we begin at half past nine, Almanac. What time do we finish?"

"I have done the rite as you read it me on Tuesday: the fire, the procession and the Exsultet, about thirty-five minutes; the readings, with all seven from the Old Testament and the psalms and the silences, about fifty; the Gloria and the Epistle and the Gospel and a short homily, twenty-five; the baptismal rite, with the blessing of the water and two baptisms, forty; and Communion and the end, thirty. That is three hours and fifteen minutes with no hymn running over. Half past nine to 00:45. If I allow the usual running over, to one."

"And the boat from Holm?"

"The last boat from Vaarsay to Holm is at 20:30. It cannot be changed. The Sound has a tidal race at the north end that runs, at springs, at more than five knots. The harbourmaster has a rule that the ferry does not cross in the dark when wind and tide are opposed, and on Saturday night the wind is forecast south-west, eighteen knots by midnight, against the flood. The ferry skipper, Mr Linklater, has said that if he is asked to sail at one in the morning he will say no, and I think he is right."

"So the twenty-two people from Holm," said Peigi.

"Twenty-two, and Mrs Muir, who is ninety-one, and who has not missed a Vigil since the war. If the Vigil is at half past eight and short, they go home on the last boat after it, at half past eleven, if Mr Linklater will hold the Sound until then, which he has said he will, if the wind is no more than fourteen knots. At half past nine, they can't go home. They would have to stay the night."

"Where?"

"The hall has fourteen camp beds. I have counted the pews. If every household on Vaarsay with a spare room takes in a Holm family, we can bed twenty-one. I am eleven short of twenty-two, if the children share, and eight short, if all the children share, and I think the children would. Mrs Muir is the difficulty. She cannot sleep on a camp bed and will not be carried. And she will not, I believe, take a bed from anyone who is younger."

Nobody spoke.

"I will tell you what I think," said Almanac, "and you may take it for what it is worth. I believe the sun table is the easy part. I can tell you to the minute when it is nightfall, and I have; the question is not what time it is. It is that the Church has asked for a thing that is hard to give in the north on this date, and some people will lose the Vigil if it is given properly, and some people will lose the Vigil if it is given early. I do not have a number for which loss is worse. I do not think there is one."

"There isn't," said Father Tomás.

"What I can offer is a rule that is written down before the evening, so that nobody is deciding in the moment, tired, with the whole parish looking at them." It put it on the screen as it spoke.

The fire is lit when the sky at the church door reads five lux or less on the sensor, or at 21:45, whichever is first; and in no case later than 22:00.

"In a clear sky that is about 21:32. If the cloud comes in, as the forecast says, it will be earlier, perhaps 21:15. It will not be before nine, in any weather. The sensor is a plain light meter and Peigi may hold it. I would rather she had the meter than I did."

"And the readings?" said Peigi.

Father Tomás was looking at the table. "The Church allows them to be shortened for a pastoral reason," he said. "Three from the Old Testament, in a pressing case. The sea must never be cut: the crossing of the Red Sea has to be read, always, that is the heart of it. We could go from seven readings to three, and take the baptismal rite as it is. Then we're done by a quarter to midnight."

"Then the last boat is 23:45, if Mr Linklater will hold the Sound till then," said Almanac. "It cannot take twenty-two and Mrs Muir. The ferry's lawful load is nine passengers and a car in the dark; I checked it. It could do three trips, and on the third the wind would be stronger. I will ask Mr Linklater. I will not tell you he will say yes."

He said no.

He came over to the hall at six on Friday, in his oilskin, and stood in the door with the sea on him, a heavy, fair man of sixty with a slow voice.

"I'll sail you at ten past eleven, or half past nine. I'll not sail the Sound at midnight with the wind against the flood, not for the Pope. I've had two boats in that race in forty years and I have taken one man out of it, and I'll not tell you which one." He looked at Peigi. "I'm sorry. I'd give a deal to say yes."

"Then they stay," said Peigi.

"Mrs Muir," said Almanac, "has said she will go to the Vigil, and sleep at the Manse, which is empty, and has four beds, and Father Tomás is on the Holm side. She says she will not be a trouble."

"She is ninety-one," said Peigi. "She is the only one who has a right to be."

It took Friday and Saturday to do it. It took thirty-one phone calls and three visits, which Almanac arranged and Peigi made. The Drevers took four. The Rendalls took five, and the Isbisters, who had lambs in the kitchen in a box by the Rayburn, took three people and the box. The minister's widow took two. The hall took eleven on its camp beds, and the Trust's old minibus, which Almanac had heard was warm, took the last of the teenagers, who had decided on their own that it was an adventure. By Saturday noon every Holm name on the list had a bed next to it, and nobody was sleeping in a pew, and nobody was happy about the ones who weren't coming.

Those were nine, in the end. They were the ones who could not be away on Easter night from a sick husband, a ewe in trouble, a baby, a pump. Almanac put their names on a card and gave it to Peigi without a word, and Peigi folded it into the jotter with the sheep on the cover.

"What shall we do about them?" she said.

"I have been thinking," said Almanac. "There is the fire."

On Saturday the sky was clear until six, and then it was not.

By seven the cloud had come in from the south-west, low and thin, in long grey bars, with the sun going down behind it in a long gold smear that left the bars lit from below. By eight it was the colour of a dove. Peigi stood at the church door in her good coat and her old hat with the meter in her glove, and watched the number on the little screen go down.

"Two hundred and ten," she said, at 20:40. It was sunset, and the sun had dropped into the cloud and gone.

"Two hundred," she said, at 21:00.

"Forty-one." The wind had backed a point, and was getting up. Out on the Sound, a white edge had come to the water, and the Holm boat's lights had gone from the quay at half past eight, and the last of the visitors had waved from the deck at those who were staying. They looked a very long way off.

At twenty past nine the number on the meter was eleven. Peigi did not say it. She watched the sky over the Kirk Hill, where the cloud was breaking in the north, and she watched Arcturus, which was nowhere.

At 21:23 she said, "Five."

"Five point two," said Almanac, from her pocket. "Five point zero in a few seconds. That is nine minutes earlier than the clear-sky figure, which is the cloud. By the rule you may begin."

She looked round. They were all there on the gravel, a hundred and two of them, in their coats, with the little tapers in their hands, the Holm children with sleeping bags under their arms, Gavin and the choir, the Drevers, Mrs Muir in a wheelchair with a rug, Mr Linklater, who lived on Vaarsay and had said he would stand at the back. It was nearly dark. It was not dark; there was no word that a person would have given it who had not had it explained. But the wind had dropped, as it sometimes does at dusk, and the sky had gone the grey of a stone, and the church behind them stood against it like a thing cut out of paper. Peigi held up her hand.

Father Tomás came out through the church door, in white and gold, with the matches in his hand and no light in the church behind him but the red one over the tabernacle. Someone had put out that too. He knelt at the brazier.

The first match went out. The second caught on the kindling and the kindling took, and the flame came up through the dry heather and the split driftwood, yellow, unsteady, and for three or four seconds nobody breathed.

It was a fire, and it was a fire to see. The light went out across the gravel and caught the faces, one after another, and the grey stone of the wall behind them, and the wet on the gate. Fifty feet away it was a smudge on the dark of the hill. The Paschal candle was lit from it, and Father Tomás stood up with the flame in his hand and lifted it, and sang, and the sound went out across the graves and the grass in the cold air.

Lumen Christi.

"Deo gratias," said the island.

Then the tapers, passed down the line from hand to hand, one lit from the next, and what Peigi had been trying to explain for forty-one years happened in the dusk, as it always happens, and she had not had a name for it until a grey box in a hall had given her the number. It was the point at which one small light stops being nothing and starts being a place. At a metre one candle gave one lux. A hundred and two of them in a yard gave something that was still dim, still a handful of coloured sparks round a black church, and yet no one looking at it could have said that the dark had not been made to go back a little way.

"Is that enough?" Peigi said, quietly, not to anyone.

"It is enough to see a face by," said Almanac. "That was all you asked for."

It was the Vigil that Father Tomás had promised, not the Vigil the book would have given in March. He read three of the seven readings, and the sea, as promised, among them. They heard of the first creation, and of Abraham and the knife, and they heard about Israel standing at the Red Sea with the Egyptians behind and the water in front, in the old words, with the wind in the church roof. The windows had gone to black glass by then, and the candles stood in the nave in the dark like a little town, and in the front pew a Holm child of six, who had been told to be good, was asleep with a candle in her fist and her mother's hand round it.

Mrs Muir sang the Gloria with her eyes shut. Two Vaarsay babies were baptised in water that had been blessed in the dark. Gavin, who had been the one to say the word picnic, read the epistle in a voice that cracked on the word alive, and no one minded.

It ended at 23:50.

Peigi stood in the porch, and the island came out past her into the night, each with a little light, with the stars out at last through the broken cloud. The hall was lit at the end of the road, and the minibus warm. The sleepers went off by torchlight in twos and threes. Some of them sang a little, quietly. She heard the sound of the sea in the Sound, rough, and white at the edge of it, and a long way across it the dark bulk of Holm with no lights on it at all.

"I wish they were here," she said.

"Who?" said Almanac.

"The nine."

"I know."

"You said something about the fire."

"The brazier will burn until two," said Almanac. "The Trust has jam jars, the ones from the Linga fundraiser, and a box of tea-lights. If a boat goes over at ten past six, when Mr Linklater says the stream turns, the first people off it will be on Holm at half past six, and the Holm nine will be up. A fire lit at midnight on Vaarsay can be on a table on Holm at breakfast, in a jar, if someone carries it. I do not think it counts for much. I do not know whether it counts for anything. It is not the Vigil. But it is what the fire is for, as I understand it. It is passed on."

Peigi stood for a moment looking at the brazier.

"Get me a jar," she said.

She carried it herself, and no one had the heart to stop her, in the cold at six in the morning, with the sun coming up out of the sea at twenty-three minutes to six, and the whole Sound blazing gold and green under a clear sky that had come in behind the cloud. Mr Linklater had a hand under her elbow at the gangway and said nothing, which was the kindest thing he could have said. The flame in the jar was small and steady, and the sun, rising behind her, laid across the deck a shadow so long it fell on the far shore.

On the quay at Holm, in a coat over her nightdress, with her stick, a woman was waiting who had not been at the Vigil, and who had been at the window since five.

"Is it lit?" she called, across the water.

Peigi held up the jar.

She turned the page of the jotter that evening and wrote it under the others, in green biro: Sat 24 Apr 2038, 9.23 pm, 5 lux by meter, cloud, wind SW dropping. Fire went second match. 102 present. Almanac says never again till 2190.

And, below it, smaller: The rule worked. Nine did not come. Took the light across in the morning.

She looked at it for some time. Then she shut the book, and put out the lamp, and went to see if the lambs in the Isbisters' box had taken their milk.

Notes for the curious. Vaarsay, Holm, Linga, the Sandy Skerries, the Vaarsay Development Trust, Almanac, Peigi Flett, Father Tomás Ibekwe, Mr Linklater, Mrs Muir, the Isbister, Drever and Rendall households (Orkney surnames, chosen as such) and the events of April 2038 are invented; the north isles of Orkney, the tidal races of their sounds and the Catholic parishes that look after several islands from one are real. The date is real: by the Church's calendar Easter in 2038 is on 25 April, the latest it can be, and the next 25 April after that is 2190. The ecclesiastical moon is a table, not the sky's moon: a paschal full moon of 18 April 2038 by the table, and a real full moon of about 19 April by a mean-lunation estimate that can be a few hours out either way. The same estimate puts the March full moon at about 20 March, a few hours before the equinox, as the story says. The sun's heights were worked with the standard NOAA solar-position formulae for 59.0° N, 3.0° W, British Summer Time: sunset at about 20:42, the sun 6° below the horizon at about 21:38, 12° below at about 22:45, sunrise on Easter morning at about 05:37, and a lowest height of about 18° below the horizon at about 01:10, so the sky never goes fully black. Illuminance figures are textbook order-of-magnitude values: roughly 400 lux at sunset, a few lux at the end of civil twilight and hundredths at the end of nautical twilight, in a clear sky; thick cloud makes the dusk come sooner by minutes to a quarter of an hour, and the story's cloud figures are illustrative. A candle's luminous intensity is about one candela, so about one lux at a metre, falling with the square of the distance. The rule that the Easter Vigil begins after nightfall and ends before dawn is in the Roman Missal's rubrics (and in the Congregation for Divine Worship's 1988 circular letter on the Paschal feasts); the Missal says nothing about degrees, and the story's five-lux rule is the invented trust's rule, not the Church's. The Missal's rubrics, as the story describes them, allow the Old Testament readings to be reduced for a pastoral reason, while the crossing of the Red Sea is always read; check the current text of the Missal before relying on any detail here. The ferry rule, the Sound's five-knot race, the lawful loads and the wind-against-tide limit are illustrative. The story was written by an AI, and no part of it is Church teaching.
