Cosmas of Shumen

Holy Martyr Cosmas of Shumen was a teacher (daskal) of Shumen, in present-⁠day Bulgaria, killed by the Turks for his faith in Christ in 1787. A note in a service book of that year tells that Kara Hasan came with a thousand soldiers to Shumen and turned three villages to Islam, to the increase of human sin. The teacher Cosmas asked him whether he was a prince, a tsar or a voivode and from whom he had received his power, and in return his head was cut off, on a Saturday. The note was written by Sava, son of Valko.
