The history of criminal law deserves more attention here. However, dealing with witchcraft makes me uneasy in view of the prejudices coming into view and the need to correct the bias of popular views of witches and sorcerers. A few days after spotting a newly digitized archival series with acts concerning witchcraft trials in Early Modern Switzerland I saw an installment of a National Geographic tv series on witchcraft which convinced me a sober but telling representation of this subject is indeed possible. Coping with biases and prejudices is perhaps inevitable for this subject! Studying the impact of legal and illegal violence and injustice is certainly a part of doing legal history.
Recently the Archives de l’Ancien Év6eché de Bâle (AAEB) in Porrentruy launched the project Crimes et châtiments for the digitization and transcription of trial records. Thanks to detailed repertories the dossiers and trials have become very much accessible. The project contains some 160,000 digitized pages from 1491 to 1797, occupying 25 meters in the holdings of the AAEB. No wonder the sheer scale of this project led to the use of computerized transcription with Transkribus. In this post I will look at various aspects of this Swiss project, and I will look how it can contribute to more insight into witchcraft in Early Modern Europe. Of course I will also look at some of the latest developments around Transkribus.
An archive on the move

Let’s start with a look at the AAEB itself. The history of its holdings is decidedly interesting. The website of the AAEB is accessible in German and French. The German version for the digitized records at Transkribus alerted me to the nature of the old diocese Basel, and the main website gives much further information in the form of a general sketch, a timeline for the diocese, a timeline for the locations of the diocesan archive and references to scholarly literature. The diocese Basel was a prince-bishopric (Fürstbistum, principauté épiscopale), meaning the bishop exercised both ecclesiastical and secular power. To complicate things, some territories were part of the Holy Roman Empire. In the wake of the Reformation which started quite early in Basel the bishop moved to Porrentruy in the Jura region near the French border. Interestingly, the cathedral chapter went to Freiburg im Breisgau, and later on it came to Arlesheim. This peculiar geographic and legal position led to impact coming from two directions. The French Revolution hit a part of the prince-bishopric, as did the secularisation of German ecclesiastical territories in 1803 for the other parts. For the part of the diocese closest to France you can even distinguish three periods between 1792 and 1815. In 1815 the Congress of Vienna added further changes to the geographic extent and status of the diocese Basel.
In 1792 the bishop had to flee from Porrentruy when French troops occupied the town. A substantial part of the diocesan archive was transferred to Vienna. The canton Bern asked the Austrian government to return these records, and in 1817 they were stored at the town hall of Bern. In 1842 these records were reunited with the parts that had remained at Porrentruy. Between 1898 and 1963 the archival collections – archival collections of some former religious institutions in the old diocese Basel had meanwhile been added – were kept again at Bern; from 1940 they were kept at the state archives of Bern. In 1979 the Francophone canton Jura was newly formed which agreed in 1985 with the canton Bern to the foundation of a private institution for the AAEB to prevent a splitup of materials. The cantons Basel Land (1997) and Basel Stadt (2008) joined its governing body, too.
To say the least, I was genuinely surprised about the present location of the old diocesan archive of Basel. It would take much space here to refer here in any detail to institutions in Basel where you might find more materials, such as the university library in Basel, with digitized manuscripts at the portals e-manuscripta and e-codices, and also some relevant digitized records for the diocese Basel at SwissCollections, the state archives of the canton Basel Land in Liestal, and the city archives of Basel, a bit confusingly named the Staatsarchiv Basel Stadt. Luckily there is an online repertory Kirchliche Bestände in schweizerischen Archiven for finding ecclesiastical archival collections in Swiss holdings. At Porrentruy you can find also the Archives cantonales jurassiennes (ArCJ).
Focus on sorcery in Switzerland

Faithful readers here are used to my generous sprinkling wih links to online references, but the short notice about the project of the AAEB in September 2024 at the Swiss history portal infoclio contains a fair number of links, too, and its enumeration of subjects for which the digitized records and transcriptions contain important information can scarcely be bettered. The AAEB is home to some 1,300 meter archival records in its holdings. The 25 meters included in the project Crimes et châtiments is a relatively small part of it. The inventories of the AAEB can be searched online on a separate platform with a search interface in German, French and English. The AAEB provides you also with a concise overview of its holdings (État des fonds, 2024 (PDF, French), but you can also use the dynamic tree overview at the inventories platform. You may want to search for literature in the online catalog of the AAEB´s library with some 15,000 items, accessible as part of the RBNJ portal for the Réseau des bibliothèques neuchâteloises et jurassiennes. This catalog can easily filter for digitized publications, for example for the edition by Joseph Trouillat of the Monuments de l’histoire de l’ancien évêché de Bâle (5 vol., Porrentruy 1852-1867).

The État des fonds makes it clear the digitized trial records stem from the main série B created in the eighteenth century for the socalled temporalia, the secular records of the old diocese Basel, the principauté. The inventory numbers B 168/14 to B 168/19 of the subseries Sorcellerie – Criminalia in sortilegiis, veneficiis et maleficiis have been digitized and (partially) transcribed. These six blocks cover the period 1546 to 1670, with a clearly higher frequency of cases between 1602 and 1621. With 42 cases in 1611 and 1612 this period had the highest number of cases (B 168/16).
The second digitized series are the procédures criminelles (AAEB, Principauté / Justice / PCrim) which covers the period 1461-1797, however, with only a few records from the fifteenth century. With 22 meters this is the most voluminous part of the project. The finding aid points you to some relevant records in other series, too, which have not (yet) been included in the digital project. The third series brings you the sentences in criminal trials, preserved in the Criminal-Bücher – Registres des sentences en matière criminelle, 1656-1792 (AAEB, Principauté / Codices / sous-série 205A to 205F). Five volumes with sentences remain; volume 205E covering the years 1767 to 1788 has been lost. For the record I would mention here Cod. 207 to 297, a series of protocols with appeals in civil cases from the sixteenth and seventeenth centuries. It pays off to read the notes for each series and subseries of this project, and to check also other parts of the section for Justice.
In my view it is important not to jump without much ado to the digitized archival records of the AAEB, but to see and acknowledge first of all their archival context, the limits in time and space and possible lacunae in the record series. The clearest gaps are the absence of trial records after 1670, and the lack of sentences in criminal trials before 1656. At its Transkribus subdomain the AAEB gives a most useful general overview of the records included in the project and how to navigate to them. Not every record has already been transcribed. The AAEB created a list for the nearly one thousand persons – mainly women (92 percent) – put to trial. The database with more information than displayed in the list view can be downloaded in the Excel format, too. A useful tool, too, is the word list (abécédaire) of (legal) terms occurring in the witchcraft trials, but surely more terms deserve explanation. The AAEB presents a page with some examples of phenomena associated with witchcraft and particular steps in trials with links to the records. The German version of this page is more detailed and refers to different cases. Both the French and the German version of a concise PDF offer a summary view by Jean-Claude Rebetez of witch hunts in Swizerland from the fifteenth century onwards.
Tracing and judging sorcery
Before discussing the merits of his summary we should finally look at the digitized archival records and the accompanying transcriptions. By now you might still detect my hesitation in dealing with witchcraft. Frankly the very tv documentary series Witches: Truth behind the trials, seemingly separating the interpretations of what happened in six countries entirely from the historical records, is to blame for my awareness. No trial records come into view. To five European countries (England, Ireland, France, Germany and Sweden) the Salem witch hunt in Massachusetts of 1692 has been added. The Dutch Republic and Switzerland are not dealt with.
Each installment of this series gives ample space to comments by scholars as a kind of running commentary on re-enacted scenes shown in slow motion with almost no sound. Quite often only darkly looming forests are shown, thus adding gloom to stories already themselves sufficiently sad and tragic. It distracts attention from the often most sensible views of the contributing scholars. For me personally a revealing aspect is the role of church ministers in the Salem and Sweden episodes. The very authority of the persecutors in the English episode – with the infamous selfstyled witchfinders Matthew Hopkins and John Stearne – was most questionable. The start of the Salem hunt at the very moment of the absence of the English governor of Massachusetts, away to England to receive a new charter for the state as a foundation of political and legal insttutions, is also remarkable. I sorely miss any attempt to show the work done to reach the interpretations offered. For me showing some part of their research, a view of historians at work searching, transcribing and thinking, would make things much more lively and interesting. Apart from repeating some recurring elements of the European witch hunts the most obvious omission is the lack of a sustained attempt at a comparison of events in the various countries.

Surely trial records have their own bias, silences and tacit understandings which need to be detected and explained. Historians as the late Natalie Zemon Davis have taught how important the argumentative power of a narrative is in a legal context. The three digitized series of the AAEB at Transkribus can be approached in two ways; the search interface has three languages. Using the Explore option leads you to either a browsing window (Documents) or to the archival hierarchy where you can navigate the three record series (B 168, Cod. and PCrim). You will need this search way in particular when no transcription is yet provided. With the Search window you can enter a free text search, with as an advanced option the use of fuzzy search at three levels. In my browser the advanced options were even nicely translated into Dutch. The search results can be filtered using the documents list on the left side. You can adjust your view to show only text, only images or both text and image. By clicking on a result with an image you arrive at the image and its transcription. With the View in document button you can start navigating within a document.
It would be strange to single out here any case or record as exceptional or regular without thorough knowledge of these rich resources concerning nearly one thousand cases. Having online access to both trial records and sentences gives substance to the possible reconstruction of events. It is most helpful to have access to both ordinary criminal trials and trials concerning witchcraft and sorcery. This enables a wider approach to events and their context, and it helps to view better the changes in the way courts dealt with specific cases.
In his brief article Jean-Claude Rebetez gives some firm ground for further study. He mentions some seminal documents and works from the fifteenth centiury which prepared minds for the persecution of suspect people. He clearly indicates how the Constitutio Carolina was the main source for procedure in criminal cases. Rebetez mentions the number of 110,000 European witchcraft cases, 10,000 of them from Switzerland. For the cases heard in the prince-bishopric of Basel no modern monograph exists. He points to differences in individual territorial units (Vogteien, bailliages). The religious tensions between Catholics and Protestants could be more marked in politically fragmented regions. The AAEB database of victims helps you very much to spot local differences.
Rebetez mentions also as important factors behind the witch hunts the centralisation of power, the background of wars and civil wars and the impact of the Little Ice Age (1550-1750). Theological views of magic and withcraft, too, changed over the centuries. Only few authors such as Johannes Wier and Balthasar Bekker questioned the belief in witches fundamentally. In the Renaissance period men increasingly marked popular practices as superstitions. Learned works such as the Démonomanie des sorciers of Jean Bodin (1580) prepared their minds to detect sorcery and witches more readily. In particular women with a weaker social position were in danger of being singled out as potential witches which had to go to trial. Judges were eager to frame women’s behaviour using suggestive questions from views biased against women. Added to all these matters were the terror and actual use of torture and the threat of cruel executions. In his most useful nutshell sketch Rebetez could perhaps have stressed the fact the Basel records still have to be studied in their full width and context. On the website the AAED mentions the division between a Catholic and a Protestant part of the Jura as one of the themes open for further research. Rebetez finally notes the variety of disciplines investigating this subject, each with its own qualities and perspectives, yet another reason to stay aloof from monolithic interpretations.
Some closing remarks
In the week I prepared this post news came the foundation for a national Dutch monument to commemorate the Early Modern witch hunts choose the town Roermond in the province Limburg as the location for a monument, to be revealed in 2026. The foundation Nationaal Heksenmonument choose Roermond because of events in 1613 and 1614 which led to the execution of eighty women. Other possible locations were ‘s-Heerenberg where a witch was burnt alive in 1605, and Oudewater, known for its Heksenwaag (weighing house), mentioned here ten years ago in my post Weighing the witches at Oudewater. In my 2015 post Breugel;s bewitching legacy I pointed already to the event in 1605 at ‘s-Heerenberg. Both posts contain more remarks about the difficulties of dealing in a sensible way with witchcraft and its imagery; you will find also references to some scholarly literature and websites.
Among the public transcription models of Transkribus 35 models are marked as German. Only one of them stems from Switzerland, a model for the council notes of the city Zurich in the eighteenth century created by the Staatsarchiv des Kantons Zürich. I could not quickly find information at the AAEB website on the specific use of any public model. By the way, lately a glitch at the Transkribus portal had removed the search function for the more than hundred public models. Luckily things could be repaired rapidly.
For me the importance of this project is the chance to look not only at archival records with transcriptions concerning witch trials, but having at hand also other records of criminal procedures and access to court sentences. The diocese Basel had an interesting location within Europe as a part of the Holy Roman Empire close to France. It invites historians and the general public to look again at the long history of prejudices and violence against women. It calls for caution in pinpointing decisive causes and monocausal explanations. European history is characterized by the multiple interplays of peoples and their views and actions, and it is a mistake to picture Early Modern Europe as a completely unified continent in most aspects.
Perhaps as interesting as the wave of the witchcraft craze is the slow disappearance of witch trials, with again various possible explanations. As long as legal records can contribute to understanding the history of witchcraft and the way women were treated by the law legal historians will have to deal with this part of their field. It will help them to perceive the limits of justice, the powers of injustice and the stories of outright violence. In fact we had better not leave it only to other research fields less closely connected with law and justice.
