Martyrdom
The fuller traditional account relates that Stamatius came to Constantinople in or around 1680 as part of a delegation of his countrymen seeking relief from an oppressive tax collected for the Ottoman court. After the delegation was expelled and beaten, Turkish officials detained Stamatius and brought him before the Vizier, slandering him with the claim that he had earlier accepted Islam and was now openly living as a Christian — in Ottoman law an apostasy from Islam punishable by death.
Stamatius rejected the accusation and steadfastly confessed his Christian faith. The synaxarion relates that he endured torture and repeated questioning without yielding, and that the Vizier finally ordered his execution. He was beheaded, by tradition near Hagia Sophia, on August 15, 1680.
