As a result of rapid advancements in computer science during recent decades, there has been an increased use of digital tools, methodologies and sources in the field of digital humanities. While opening up new opportunities for scholarship, many digital methods and tools now used for humanities research have nevertheless been developed by computer or data sciences and thus require a critical understanding of their mode of operation and functionality. The novel field of digital hermeneutics is meant to provide such a critical and reflexive frame for digital humanities research by acquiring digital literacy and skills. A new knowledge for the assessment of digital data, research infrastructures, analytical tools, and interpretative methods is needed, providing the humanities scholar with the necessary munition for doing critical research. The Doctoral Training Unit "Digital History and Hermeneutics" at the University of Luxembourg applies this analytical frame to 13 PhD projects. By combining a hermeneutic reflection on the new digital practices of humanities scholarship with hands-on experimentation with digital tools and methods, new approaches and opportunities as well as limitations and flaws can be addressed.

Although seemingly bizarre and barbaric in modern times, trial by ordeal-the subjection of the accused to undergo harsh tests such as walking over hot irons or being bound and cast into water-played an integral, and often staggeringly effective, role in justice systems for centuries.

In "Trial by Fire and Water," Robert Bartlett examines the workings of trial by ordeal from the time of its first appearance in the barbarian law codes, tracing its use by Christian societies down to its last days as a test for witchcraft in modern Europe and America. Bartlett presents a critique of recent theories about the operation and the decline of the practice, and he attempts to make sense of the ordeal as a working institution and to explain its disappearance. Finally, he considers some of the general historical problems of understanding a society in which religious beliefs were so fundamental.

Robert Bartlett is Wardlaw Professor of Medieval History at the University of St. Andrews.
