Newly Converted Bulgaria Meets the Heresies on the Verge of the 10th Century

The paper explores the sources, from which the newly converted Bulgarians could obtain information about the deviations from Orthodoxy and the most famous heresiarchs. It seems that most of the notices are contained in the translations dated to the first decades of the 10th c. during the reign of Simeon the Great. The fact should not surprise us given the role this ruler played in the cultural and literary policy of the new Christian state. Could we however speak about a conscious policy in this regard, or is this a mere coincidence?
