Local copy: report.html (the same HTML).

Verdict label: leading candidate. A recruited departure for the new settlements east of the Elbe ranks first of seven explanations at 42 in 100, the other six together carry 58, and a real loss of Hamelin's young people in or close to 1284 is put at 80 in 100.

## What happened, as Hamelin tells it

Hamelin (in German, Hameln) is a small town on the river Weser in northern Germany, some 40 kilometres south-west of Hanover. The story it has told since the fifteenth century: on 26 June 1284, the feast day of Saints John and Paul, a handsome, well-dressed stranger with a silver pipe came in through the gate on the river side, played through the streets, and led 130 of the town's children out through the gate on the far side, towards the hill outside the walls where the town carried out its executions. The children vanished; their mothers went from town to town and found nothing; and the town, the story says, counted its years from that day. The rats, the unpaid fee and the mountain that opened to take the children in first appear in books of the 1550s and 1560s; the lame boy left behind first appears in an English book of 1605, from which Robert Browning took his poem of 1842.

## Why it is a mystery, and what each side says

Nothing written at the time survives. The earliest account is a short Latin note added about 1430–50, some 150 years after the event, to a manuscript now in the town library of Lüneburg, a city about 150 kilometres to the north-east (the Lüneburg note); its writer says he copied it from "an old book". The house inscriptions that give the date and the number begin in 1525, and the first printed accounts date from 1556. Historians therefore argue about whether anything happened at all, and if it did, what. Hans Dobbertin, a local historian who collected the sources in 1970, and Jürgen Udolph, a German specialist in place names, hold that the "children" were young people recruited for the German settlement of the lands east of the river Elbe, which was actively under way in the 1280s, and Hamelin's museum today takes the same view. Others read the story as a religious procession of the young that came to grief; as an accident on the hills outside the town (the folklorist Waltraud Woeller in 1957–61, the local historian Gernot Hüsam since 1990); as a levy of young men for a local war (Fein, a garrison preacher, in 1749; Thomas Küntzel in 2010); or as a crime. Some folklorists doubt that any single event lies behind the tale. The version most often repeated in English, that Udolph proved where the children went by feeding Hamelin's surnames into a computer, rests on a press report of 1998; Udolph published no such study.

## How the case was judged

The evidence is every surviving witness to the story, read in order of date and, wherever possible, from the originals: the Lüneburg note from the library's online facsimile, the inscriptions from the standard edition of 1989, the sixteenth-century prints from digitised copies, and the medieval charters of Hamelin and of Pomerania from the printed charter books. The method is to list what the tradition claims and when each claim is first attested, to score seven explanations against those claims and against the documentary record of the 1280s, and to attach to each explanation a probability expressing an estimate of its likelihood. The result is a ranking of the seven explanations by estimated likelihood; it does not establish which of them is correct. A real loss of young people probably lies behind the tradition (80 in 100, with the caution that no surviving witness is older than about 1430); a recruited departure for the new villages east of the Elbe is the best single explanation at 42 in 100, which ranks it first, with the other six together carrying 58; and the sources cannot say where the group went. Emigration is therefore the leading candidate: several explanations remain possible and are put in order, it stands ahead of each rival, and the order can change when one judgement changes. Two documents not seen used for the legend before came out of the charter books: a bishop's letter of 1502 that fixes the place the inscriptions name, and a Pomeranian charter of 8 July 1284 that puts a count from the next lordship east of Hamelin at the Pomeranian duke's court twelve days after the date of the exodus. Neither document shows what happened in 1284. The counts of Spiegelberg, that family, held Coppenbrügge on the road east from 1281; they show that a channel to the east existed; no evidence shows that a Hamelin group used it. The "surname proof" has no published basis.

## What the sources attest, and when

Who is who in the table: Erich is Samuel Erich, rector of Hamelin's Latin school, whose book of 1654 preserves several lost texts; Fincelius is Jobus Fincelius, a Jena physician whose book of marvels (1556) is the first printed account; Weyer is Johann Weyer, a physician whose book on demons (1566, expanded 1568) is the first Latin print; the Zimmern chronicle is a Swabian family history of about 1560; Backhaus wrote a rhymed chronicle of the town in 1589; the Passionale is a service book of saints' lives from the town's principal church, now lost; DI 28 is Christine Wulf's 1989 edition of Hamelin's inscriptions in the Deutsche Inschriften series.

| Element of the story | Earliest witnesses | Standing |
|---|---|---|
| Year 1284, feast of SS John and Paul | Lüneburg note (c. 1430–50); lost Passionale verses (undated, known from Erich 1654); inscriptions from 1525 | the tradition's stable core, about 150 years after the event |
| 130 "pueri" / "kinder" | the same three witnesses | stable; the word covers unmarried young people, servants and crew |
| "26 June" | a conversion of the feast day; first on the Markt 1 inscription (1525?, text via Erich 1654), then Weyer 1566/68 | derived, not independently attested |
| "Monday" | computed from the feast day (compute.py) | true only if the year and the feast are |
| A piper (or magician) leading the children out of a gate | Lüneburg note; then every witness from 1556 on (Fincelius 1556, Neues Tor 1556 "magus", Weyer 1566/68, window 1572, Backhaus 1589, beam 1602) | the "well dressed" young man with a silver pipe becomes a piper in a coat of many colours from Weyer 1566 |
| Calvary / Koppen | Lüneburg note ("locus Calvarie vel decollacionis"); lost Passionale verses; Weyer 1566/68; window 1572; Backhaus 1589; beam 1602 | stable from the earliest layer; placed by the bishop's letter of 1502 at Klein-Afferde, a village just outside the east gate |
| A search that found nothing | Lüneburg note (the mothers, "from town to town"); Fincelius 1556 in another form (the parents, "on water and land in all places") | two forms, both late |
| Entry by the Weser gate, exit by the east gate, the silver pipe, the mothers running from town to town | Lüneburg note only | single witness, citing "an old book" and the mother of a dean whose will is dated 1378 |
| Rats | Zimmern chronicle (c. 1559–66), Weyer (1566/68) | late accretion; never on a Hamelin inscription |
| Anything surviving from the 13th or 14th century | none | the "window of c. 1300" is Hans Dobbertin's undocumented date, rejected by Christine Wulf (DI 28, no. 76†); the Passionale prayer, sometimes dated to the 14th/15th c., is lost and known only from Erich 1654 |

The page narrates the event only as the tradition tells it, and tests the explanations against the tradition as attested, not against facts of 1284.

## Probabilities

The figures below are my judgements, conditional on the seven hypotheses listed and on the weights I chose; they order the explanations by my estimate of their likelihood and do not count as evidence. Recruited for the new settlements in the east and led away by a locator (the contractor who gathered settlers for a lord) 42 · no single real event, a legend grown around the town's habit of dating years "after the children left" 18 · a religious or Midsummer procession of the young (a "Kinderfahrt") that dispersed or came to grief 13 · an accident near the town 9 · a military levy or ruse (for the siege of the Everstein castles near Hamelin in 1284, or another feud) 8 · something else, an epidemic or an unrecorded calamity 6 · abduction, sect or murder 4.

Sensitivity: one judgement carries the ranking, the 80 for a real loss. Holding the event explanations in the same proportion to each other, at 50 "no single event" rises to about 50 and emigration falls to about 26, still first among the event explanations; at 90, emigration rises to about 46. Only the first digit of each figure carries any information. Four explanations are left off the list because they fail the year given by the Hamelin witnesses, or fail the settlement record: the children's crusade of 1212, the battle of Sedemünder near Hamelin (1259/60), the Black Death (1347 onward) and the German settlement of Transylvania.

## What is new here, and what only agrees

None of the source corrections is new evidence in the sense of an unpublished document; each is a new use or a re-reading of something printed or digitised (Fink's Urkundenbuch of 1903, Prümers's Pommersches Urkundenbuch of 1885, the Wolfenbüttel facsimile of the Lüneburg manuscript, Udolph's article of 1997).

1. New use of a printed source. A letter of 6 July 1502 from the bishop of Minden, whose diocese Hamelin belonged to (printed in the town's charter book, Urkundenbuch des Stiftes und der Stadt Hameln II, no. 663), documents a Calvary with stations "before the east gate … to the boundary of Klein-Afferde, commonly 'beneden den Koppen'". It fixes what the inscriptions of 1525–1602 meant by "Koppen", agrees with Samuel Erich's location of 1654, and rules out Kopahn, a manor on the Baltic coast of Pomerania (Dobbertin's reading), and Coppenbrügge or the Ith ridge thirteen kilometres east of Hamelin (Woeller's and Hüsam's reading) as the meaning of the phrase. It cannot establish anything about 1284: not that the group went that way, not that a Calvary existed there in 1284, not a destination. I have not found it cited in Udolph 1997, Alfred Cammann 1984, Wulf's commentary in DI 28 or the theory literature I could read; Hüsam's 1993 paper on "Calvaria" and volume I of the Urkundenbuch (Meinardus 1882) were not available to me, so the claim of novelty is qualified.
2. Checked against the original. The Pomeranian charter book (Pommersches Urkundenbuch II, no. 1308) shows Count Nicolaus of Spiegelberg with his brothers at Stettin, the duke's seat (today Szczecin in Poland), on 8 July 1284; the "† 1283" of the Wikipedia genealogy, repeated in recent summaries, is wrong (Dobbertin had the right date, as Cammann's summary of him in 1984 shows). The charter therefore supplies a corrected date and shows that a channel to the east existed; it does not show that any transfer of people from Hamelin took place.
3. Checked against the original. The Lüneburg note (Lüneburg town library, Ms. Theol. 2° 25, fol. 268r), re-read from the online facsimile: the text circulating on Wikipedia has no basis for its heading "Fabula exodi Hamelnsis" or its "fere", the scribe wrote "valvam" over a cancelled "portam", and the note contains no Latin verses.
4. Correction. The "surnames fed into a computer" story (1998 press) has no counterpart in Udolph 1997, which is a place-name audit with a short section on medieval bynames; several of the transferred place names are attested before 1284, so the names show that a settlement corridor existed; they do not show that the group of 1284 travelled it.
5. Agrees with Wulf 1989: the window "of about 1300" is Dobbertin's undocumented date, the oldest inscription is 1525, and the "1384: 100 years since our children left" record cannot be traced to any scholarly or early-modern source.
6. Agrees with Dobbertin, Udolph, Norbert Humburg (editor of the 1985 volume of the Hamelin conference on the legend), Wolfgang Mieder (author of the English handbook on the legend, 2007) and Hamelin's museum in ranking emigration first, at lower confidence; the medieval historian Bernd Ulrich Hucker's objection of 1985 (a lawful emigration should have left traces) stands as the counter-case, and the accident, procession and levy readings have advocates of their own.

The reconstruction itself (a recruiter, a departure east, a loss on the road) is an inference from a fifteenth-century tradition; the report ranks it first and does not claim that it is established.

## What would overturn the verdict

A charter, a locator's contract or a town book of about 1284–1295 naming settlers "de Hamelen" in a new village in Pomerania, the Neumark (Brandenburg's lands east of the Oder), Prussia or Brandenburg would, on these weights, push emigration above 70 and fix the destination; the Pomeranian volumes for 1284–1300 contain no such entry, and the Prussian, Brandenburg and Mecklenburg charter books and the earliest burgher books of Riga, Danzig, Elbing, Stettin and Prenzlau have not been searched systematically. A fourteenth-century Hamelin document mentioning the exodus, in the collegiate church's records or in the "old book" the Lüneburg writer used, would settle whether it happened; a full search of the Hamelin records in the Lower Saxony state archive in Hanover finding nothing would push "no single event" up. A mass grave of the 1280s at the Koppen (the Afferde hills) or on the Ith would revive the accident theories; nothing of the kind has appeared in seven centuries of quarrying and building there. The 1941 genealogy of the Spiegelberg counts by Hartmann, which was not obtainable, may record Nicolaus after July 1284; if he reappears in Saxony in 1285, the reading in which he himself led the group to Pomerania fails, though the channel remains possible.

## Where the report fell short

Not available: Dobbertin's Quellensammlung itself, Hartmann 1941, Hüsam 1993 and 2024, Küntzel 2010, Meinardus 1882 (Urkundenbuch I), Wauer 2000, Bichlmeier 2024. The Brandenburg land register of 1375 (the Landbuch) was available only as a scan too poor to search for names. No new document from the thirteenth or fourteenth century was found. There is no statistics or stylometry here; the computation is limited to the calendar and distance checks in compute.py.
