Fresh heresy in 11th-c. Lotharingia?

In 2016, the MGH published Benedikt Marxreiter’s edition and German translation* of a hitherto unknown text – a work on demonic magic by an eleventh-century monk, Bern of Reichenau.

As well as Bern’s treatise, De nigromantia, there also survive two cover letters, which accompanied copies of the work that he sent to people, which are also included in Marxreiter’s edition. One of these letters was addressed to Archbishop Poppo of Trier (d. 1047). Here’s a quick draft translation of a key passage:

“Those people stir up foolish, useless and vain questions, who watch the movement of the stars because they think that every human is born under a constellation, who seek answers from demons, who demand divinations, who foster the magical art, and who destroy themselves. Following the Apostle Paul’s words, they ‘introduce sects of perdition, and denying the Lord who bought them, they bring swift destruction on themselves’. We have heard that these people sprouted forth in Italy in the kingdom of Charles, emerged forth for their own ruin, came to Lotharingia and sowed the poisonous seeds of their lethal teaching, for the destruction of many. Your Authority [Poppo] resisted them according to the wisdom divinely given to you, argued against and contradicted them many times… And recently some news that was not good reached me, which reported that certain seedlings of error have again sprouted in Francia, which strive to contaminate the harvest of the catholic faith…”

What does Bern’s letter mean for students of 11th-century heresy – a long vexed historiographical field? On the one hand, it could represent new evidence for the existence and spread of heretics in post-1000 Europe, moving up from Italy into Lotharingia, and connected moreover with the well-known appearance of heretics in France around this time (e.g. the famous 1022 Orleans burnings).

On the other, it could simply show how what was changing was not the heretics but the church’s classification of people perceived as dissenters. Bern was after all a well-networked ‘reforming’ monk, closely connected with both Fleury and Gorze, and thus perhaps prone to see the devil’s work in any resistance to a programme of reform. His association of heresy with demonic magic and astrology certainly suggests that we are dealing with very thick layers of ecclesiastical interpretation. As Marxreiter points out, it certainly can’t be a coincidence that Archbishop Poppo had accused nuns in his diocese of magic, as a justification for dissolving the convent of Pfazel**.

Either way, it’s exciting to have a new piece of the heresy jigsaw to play with.
