Triantaphyllos the Martyr (1663 – August 8, 1680) is a martyr and saint of the Greek Orthodox Church. He was born in Zagora,[1] in then Ottoman-controlled Greece, and was taken captive by the Turks one day while he was working as a fisherman. He was tortured when he refused to renounce his Christian faith and convert to Islam and was eventually beheaded by his captors.[2]
