Life and Martyrdom
The sources place Eupsychius in Caesarea, the chief city of Cappadocia in Asia Minor, during the brief reign of Julian the Apostate (361-363), the emperor who sought to restore pagan worship after the Christianization of the empire. The synaxarion records that Eupsychius had entered into a Christian marriage at the time of his confession.
As the account relates, his act of destroying the pagan temple of Fortune drew the emperor's anger upon the whole city, which was punished with executions, exile, conscription of its clergy, and the looting of its churches. Knowing what his deed would cost him, Eupsychius gave away all that he owned to the poor and gave himself up to martyrdom.
After enduring prolonged torture on the rack and with iron claws without renouncing Christ, he was beheaded by sentence of the judge.
