Basque Shadows: Dersail and the Sabbat’s Treasury in Labourd (1610)
Dersail, also occasionally referred to as Detsail, is a minor figure in the history of demonology and witchcraft trials, documented primarily through French occult literature of the 19th century. His notoriety stems from accusations made during the intense witch-hunt that swept through the Labourd region (a historical province of the French Basque Country) around the year 1610. This period was famously marked by the proceedings led by the French judge and demonologist Pierre de Lancre, who documented the confessions and alleged activities of the accused in detail.
Dersail is characterized in the Dictionnaire Infernal, a seminal work of demonography by Jacques Collin de Plancy, as a sorcerer from Labourd who played a ceremonial role in the witches’ Sabbath. Specifically, he was alleged to have carried the offering basin during the rites. This duty placed him in a position comparable to a sub-deacon or official within the supposed infernal hierarchy of the Sabbat.
Confessions extracted from several accused witches during the 1610 Labourd trials claimed they had witnessed Dersail at the Sabbath, where he reportedly collected the offerings during the parody of the Catholic Mass known as the Black Mass. Furthermore, these testimonies asserted that the funds collected by Dersail were used to support the activities and affairs of both the sorcerers in the region and his own personal interests.
