Sometime between receiving news of the accession of King Louis the Child on 8 December 899 and the death of
Pope John IX in 900, Dietmar wrote a letter to the pope complaining that the latter had sent an archbishop, John, and two bishops, Benedict and Daniel, to Moravia, which was properly under the jurisdiction of the bishop of Passau. The letter is evidence that the papacy still recognized the
archbishopric of Moravia. Dietmar had a low opinion of the Moravian Slavs, describing them as clinging to pagan customs like swearing oaths on dogs. He claims they shaved their heads in alliance with the pagan Hungarians. He compares
Mojmir II's pagan ancestry unfavourable with Louis the Child's Christian ancestry. He notes that because the Bavarians could not secure a peace treaty with the Moravians, they were unable to come to Italy's aid when it was invaded by the Hungarians. As a result, he is unable to send his dues to the pope. The original of Dietmar's letter does not survive, but there are several copies. As the earliest copy is found in a manuscript alongside the
Lorcher forgeries of
Pilgrim of Passau, the authenticity of the letter has been disputed. Fritz Lošek, its most recent editor, accepts it as genuine. Since it asserts the authority of Salzburg over Passau, it is completely at odds with Pilgrim's forgeries. An English translation has been published. == Footnotes ==
