Martyrdom
By the account preserved in the Prologue of Ohrid, the three men witnessed a pagan festival at which idols were being worshipped and came forward before the assembled crowd to preach one God in Trinity. Their bold public proclamation enraged Firmilian, the regional governor of Caesarea in Palestine, who immediately ordered them to be beheaded.
The synaxarion records that they suffered martyrdom in the year 308. The Orthodox Church in America's listing summarizes the event plainly: they "were beheaded in Caesarea of Palestine during the reign of Maximian by the ruler Firmilian."
