Agathangelus was from Thrace. His secular name was Athanasius. Serving the Turks, he was forcibly converted to Islam in Smyrna. As a penitent, he was tonsured a monk on the Holy Mountain [Athos] in the Monastery of Esfigmenu. Tortured by his conscience, he desired to wash away his sin with his own blood. He departed for Smyrna where he exhibited a cross and an icon of the resurrection of Christ before the Turks. He was beheaded on April 19, 1819 in his nineteenth year. Following his death, he appeared alive to Herman, his spiritual father.
