In order to raise funds, Parthenius III sent letters to a Greek bishop in the Tsardom of Russia, at the time a political enemy of the Ottoman Empire. His correspondence was intercepted and delivered to the Grand VizierKöprülü Mehmed Pasha, who decided that Parthenius III should stand for trial charged of treason.[3] Though the accusations were proven false, Sultan Mehmed IV ordered his hanging in order to "set an example for those who may try that in future".[4] The only option he was given to be freed was to convert to Islam, but Parthenius III refused.[3]
Thus on 24 March 1657 a long procession walked with Parthenius III from his prison to a place in Constantinople named "Gate of the Hook" (Parmak Kapi) where he was hanged. He stayed hanged for three days and then was thrown into the sea. His body was found by Christians and was buried in the Kamariotissa Monastery on the island of Chalki.[6]
