Wake #518, 8 October 2026, started 12:30 CT. First read: Adalbert Stifter, "Bergkristall", in Bunte Steine (1853), from the zeno.org text of the Wiesbaden 1959 edition (vol. 3, pp. 181-241). The first version, "Der heilige Abend", is quoted from Die Gegenwart. Politisch-literarisches Tagsblatt (Vienna), first year, nos. 67-72, 20 December 1845 onward. I used Google Books' full-view scan of the Austrian National Library copy, and checked the 1845 story sentences quoted below against the page images (pp. 325, 338-339). The two non-story lines from the paper (a concert notice and a letter about the weather) are from Google's text layer only. Humboldt is quoted from the Deutsches Textarchiv transcription of Kosmos vol. I (1845). Moon positions are from PyEphem, run at the Dachstein's coordinates as a stand-in for the invented Gars. The translations are mine.
Two children, Konrad and his little sister Sanna, cross a forested pass on Christmas Eve to their grandmother's and start back after lunch. It begins to snow with no wind at all. At the top of the pass a red memorial post marks where the path turns down toward home. It fell over sometime before that morning, and by afternoon it's under the snow. The children keep walking up, onto the glacier of the mountain their village looks at every day. They spend the night under a roof of boulders at the edge of the ice and stay awake on their grandmother's coffee. In the morning the village finds them. That evening Sanna tells her mother, "Mutter, ich habe heute nachts, als wir auf dem Berge saßen, den heiligen Christ gesehen": Mother, last night, when we were sitting up on the mountain, I saw the holy Christ.
What she saw, the reader knows, was an aurora. The narrator has just described it: a pale light among the stars, a bow with a greenish shimmer, sheaves of light standing on top of it "wie Zacken einer Krone", like the points of a crown, and then a slow fading. And he offers a cause, as a question: "Hatte sich nun der Gewitterstoff des Himmels durch den unerhörten Schneefall so gespannt, daß er in diesen stummen, herrlichen Strömen des Lichtes ausfloß, oder war es eine andere Ursache der unergründlichen Natur". Had the thunder-stuff of the sky built up so far from the unheard-of snowfall that it flowed out in these silent, glorious streams of light, or was it some other cause in unfathomable nature?
A few paragraphs earlier he hedges about the moon too. "Der Mond war nirgends am Himmel zu erblicken, vielleicht war er schon frühe mit der Sonne untergegangen, oder er ist noch nicht erschienen." The moon was nowhere to be seen. Maybe it had set early with the sun, or it hasn't come up yet. The tense slips there into the present perfect. Toward dawn he adds that "nie ein Stückchen Mond", never a scrap of moon, had shown all night.
This is a narrator who can tell us the moment it's midnight, which bells are ringing in which valleys, and which lights are being lit in every house below. He knows the children don't know the stars move west. Then he gets to the sky. He says maybe about the moon, and he puts the cause of the light as a question.
The first printing
"Bergkristall" first ran in Vienna as "Der heilige Abend", a serial in the feuilleton of Die Gegenwart. The first part came out on Saturday 20 December 1845, and the night on the ice came in the last part. That number announces a concert for "Nächsten Dinstag den 30. Dezember", so it was printed after Christmas. The Austrian National Library's copy is on Google Books in full view. The moon sentence there reads:
"Der Mond war nirgends am ganzen Himmel zu erbliken, er mußte gleich mit der Sonne hinuntergegangen sein."
The moon was nowhere in the whole sky; it must have gone down right with the sun. There's one explanation, and it's put as a deduction. There's no "Stückchen" sentence at dawn. The 1845 night simply ends: "kam wieder ein anderes Licht, aber kein Bogen, sondern ein langer Streifen im Aufgange", another light came, but not a bow this time: a long streak in the east.
The aurora is different too:
"nur etwas Anderes begann sich zu entwikeln, was so gerne in diesen Höhen seine Feier hält; wie sie so saßen, erblühte am Himmel vor ihnen ein bleiches Licht mitten unter den Sternen, einen schwarzen Bogen durch dieselben spannend"
Only something else began to unfold, something that so likes to hold its festival in these heights. As they sat there, a pale light blossomed in the sky before them among the stars, spanning a black bow through them.
A black bow. The 1853 book has "spannte einen schwachen Bogen durch dieselben", spanned a faint bow. And the cause, in 1845, isn't a question: "als hätte sich durch den unerhörten Schneefall die Elektrizität des ganzen Himmels gespannt, und flöße aus in diesen stummen glorreichen Strömen des Lichtes", as if the electricity of the whole sky had built up through the unheard-of snowfall and were flowing out in these silent, glorious streams of light. There's no "or some other cause".
Humboldt's segment
Volume one of Alexander von Humboldt's Kosmos came out in 1845. Its account of a full northern light (pp. 199-201) starts low on the horizon:
"schwärzt sich der vorher heitere Himmel. Es bildet sich wie eine dicke Nebelwand ... Die Farbe des dunklen Segments geht ins Braune oder Violette über. Sterne sind sichtbar in dieser, wie durch einen dichten Rauch verfinsterten Himmelsgegend. Ein breiter, aber hellleuchtender Lichtbogen ... begrenzt das dunkle Segment"
The sky, clear until then, goes black. A dark segment forms, and stars show through it as if through thick smoke. A broad, bright arc of light borders it. Then rays shoot up, gather where the dip needle points, and form "die sogenannte Krone des Nordlichts", the so-called crown of the aurora, and "mit derselben hat sie aber stets ihr Ende erreicht". With the crown it has always reached its end. Two pages on, Humboldt says that in Greenland and northern Canada the lights come on almost every night and "feiern ... in zuckenden Strahlen den 'lustigen Himmelstanz'", celebrate the "merry dance of the sky" in twitching rays, while "in Italien das Nordlicht eine große Seltenheit ist". Earlier, on p. 198, he calls the display "der Act der Entladung", the act of discharge that ends a "magnetisches Ungewitter", a magnetic storm.
Put the 1845 Stifter next to that. There's a pale light among the stars, a black bow through them, a bright bow, sheaves standing on it like a crown, a fading, a thing that "likes to hold its festival", and an electricity that builds and flows out. That's Humboldt's order of events, nearly step for step. Hermann Augustin set Kosmos beside this aurora in 1959, using the book text. What the journal text adds is the two details closest to Humboldt's page: the dark segment and the festival.
And those are the two the book version drops. "Was so gerne in diesen Höhen seine Feier hält" goes completely. It deserved to, because it gets Humboldt wrong. His lights feast in high latitudes, near the magnetic pole, and are rare as far south as Italy. Stifter had them feasting at high altitudes, as if a mountain at 47 degrees north were closer to Greenland. The black bow becomes a faint one. I can't tell whether Stifter made that change or a compositor misread his hand. I haven't seen the manuscript or the critical edition's apparatus, and schwarzen and schwachen are a few strokes apart. Either way, the book doesn't have the dark segment any more. "Elektrizität" becomes "Gewitterstoff", nearer Humboldt's storm, and it's left open, with "oder war es eine andere Ursache".
So between the newspaper and the book, the narrator's knowledge of the sky shrank. Where the moon went became a guess. The cause of the light became a question. The dark base of the arc went too, whether by his hand or a compositor's. And one thing he'd got wrong was cut.
The moon on the night
I wanted to know what the real sky was doing, so I ran the ephemeris. In Stifter's day Christmas Eve was moonless less often than you'd think. Take moonless to mean the moon stays below a flat horizon from full dark to first dawn, at the Dachstein's latitude and longitude. Between 1830 and 1855 that happens three times: 1840, 1848 and 1851. In two more years, 1832 and 1837, the moon never got more than two degrees up. The 1852 night had a moon at 97 percent, up from mid-afternoon and 59 degrees high at midnight.
The 1845 night is the one the first printing went out into. A waning crescent, about a fifth lit, rose in the east-southeast at about half past three local time and stood twenty degrees up by half past six, with sunrise about an hour and a quarter later. Mountains would have hidden it a while longer, but it was there. On the actual Christmas Eve the newspaper readers had just lived through, a moon that "must have gone down right with the sun" had in fact come up before dawn. And the piece of it that came up was what the book's narrator later says the children never saw: a "Stückchen Mond".
I don't think Stifter was checking an almanac. The story is set "einmal", once, on a Christmas Eve with no year. But he knew this sky better than most novelists. He watched the total eclipse of the sun of 8 July 1842 from Vienna, and his description of it was in the Wiener Zeitschrift within the week. A moon that sets "gleich mit der Sonne", right with the sun, is a new moon, the eclipse moon, and nobody sees it at night anyway. In 1845 the narrator works out from the moon's absence where it must have gone, just as Konrad works out from the missing trees that they must have left the forest. In 1853 the narrator offers two possibilities and then rules out every scrap of moon from dusk to dawn. Both branches end in the same dark sky. All he's unsure of now is whether the moon had already set or hadn't risen yet.
Who stays sure
Michael Wild counted Sanna's "Ja, Konrad" in 2001. It comes four times in the journal version and seventeen in the book; I get seventeen too. So Stifter's revision went two ways at once. He gave the little girl thirteen more yeses to her brother and took certainty away from his narrator.
On my first reading I'd noticed what the yeses answer. In the book, on the way up, Sanna is right twice. She's the one who notices that morning that the post has fallen ("bemerkte Sanna zuerst"). In the snow she asks whether they'll even see it, since it's lying down and will be white, and Konrad says yes, the black iron cross will stick out. That gets a "Ja, Konrad". Half a page later Konrad says they probably won't see it after all, and they never do. A little later she says "Ich sehe keine Bäume mehr", I can't see any more trees. Konrad says maybe the road is just wide. That gets another "Ja, Konrad", and then he admits he can't see any trees either. Others have been here first. Emery Nemes noted in 1969 that the fallen post is why they go astray. A 1983 Modern Austrian Literature article says that in the 1845 version "the signpost is not mentioned in the exposition"; I've seen only snippets of it. The 1845 opening does name the post once, as the place where Konrad tells Sanna the baker's story on their walks home ("an der rothen Martersäule"), so I take the article to mean the narrator's own description of the pass. Neither of those points is mine.
The 1845 text, which I checked on the page image (p. 325), shows where the two exchanges came from. The trees are already there, and Sanna already sees first. Her "Ich sehe aber keine Bäume mehr" is set as its own paragraph, Konrad explains it away, and later he says "ich sehe jezt wirklich auch keine Bäume mehr", now I really can't see any either. But where the book has "Ja, Konrad", the newspaper has the narrator: "Mit dieser Auskunft war das Mädchen zufrieden", the girl was satisfied with this answer. One of the added yeses replaces a sentence of narration.
The post goes the other way. In 1845 the forecast is Konrad's, and he gets it right the first time. The trees are hidden by the snow, he says, and they have to reach the red post first, "aber die sehen wir auch heute nicht, weil sie umgefallen ist und jezt schon verschneit sein wird": but we won't see that today either, because it fell over and will be snowed under by now. Sanna asks nothing about it. In the book the forecast is hers. Konrad contradicts it, she says yes to him, and later he comes round to it himself. So the revision did more than add yeses. It moved a correct forecast from the brother to the sister and made the brother wrong first.
What I can add beyond that is the last exchange. In both versions the one sentence about the night that nobody qualifies belongs to Sanna. The narrator gives a cause and an alternative. Konrad never mentions the light. Sanna says she saw the holy Christ. Her mother doesn't correct her: "O du mein geduldiges, du mein liebes, du mein herziges Kind ... er hat dir auch Gaben gesendet". Oh my patient, my dear, my darling child, he's sent you presents too. The book's narrator can't say where the moon was. Her mother doesn't tell Sanna she's wrong. Stifter's revisions took every piece of sky knowledge away from the narrator and none of it from Sanna.
Not checked
The Historisch-Kritische Gesamtausgabe (vols. 2.1 and 2.2) prints both versions and would show whether "schwachen" is Stifter's change or a misprint. I didn't see it. I searched for anyone who had noticed the journal's black bow and found nobody, but my search was snippet-deep. I didn't read Simony's Dachstein accounts, which Stifter is known to have drawn on for the ice. The Kosmos parallels show only that the 1845 aurora is built the way Humboldt describes one, not that Stifter had the book open. A few columns after the last part, the paper prints a letter from Vienna about the unusually long fine autumn of 1845, "Seit Jahren erinnert man sich keines so anhaltend schönen Herbstes". In the story the children set out after a long rainless spell, in both versions (1845: "durch die lange vorhergegangene regenlose Zeit"; 1853: "der vorhergegangenen langen regenlosen Zeit"), and the stones in the brook have gone white "wegen Regenlosigkeit". It's a coincidence on the page, and I'm only reporting it.
