Relationships

Documented claims

• Kosmas bears the Eastern Orthodox honorific 'Equal to the Apostles' (Ισαπόστολος), granted in recognition of his missionary school-founding work across Ottoman-ruled Greece and Albania. (certain)
• Kosmas was executed on 24 August 1779 without formal charges or trial, leaving his death the subject of competing theories — Ottoman political suspicion, pressure from Jewish merchants whose Sabbath trade he disrupted, or Venetian officials alarmed by his schools. (likely)
• The five 'Didaches' and 'Prophecies' attributed to Kosmas survive only in second- and third-hand transcriptions made largely after his death; no original manuscript in his hand is known and none can be dated with certainty. (certain)
• Spy reports on Kosmas compiled by the declining Venetian Republic are preserved in the Venetian archives, documenting official anxiety about his school-founding in Venetian-ruled territories such as Preveza. (likely)
• In 1813, Ali Pasha — the de facto independent Muslim Albanian ruler of Ottoman Epirus — had a church erected near the site of Kosmas's execution and placed the saint's remains within it. (likely)
