This article discusses how to perceive developments in the prosecution of written pacts with the Devil in Denmark-Norway between 1634 and 1754. While existing scholarship interprets the prosecution within the framework of an Enlightenment narrative by presenting the cases as evidence of an incomplete rejection of magical beliefs, such as the possibility of making a pact with the Devil, this article investigates the cases with regard to the early absolutist sovereigns’ endeavours to deal with blasphemy offences. The medley of punishments imposed in the cases – including public confession, executions, and imprisonment with hard labour – calls for a more complex evaluation of both ruptures and continuity in the prosecution of this type of crime during the period. Through selected cases representing varying approaches of the respective sovereigns, this article analyses how the understanding and administration of the offence developed in the legal practice of the emerging absolutist state.
