Martyrdom
According to the synaxarion, the proconsul Priscus of Chalcedon decreed that all inhabitants of the city and surrounding region attend a pagan festival to worship and sacrifice to the idol of Ares, under threat of grave torments. A company of Christians, numbering about fifty and including the young Euphemia, were found worshipping the true God in hiding and refused to take part.
The accounts relate that the martyrs were subjected to various torments over a span of days, and that Euphemia endured a sequence of trials: she was bound to a wheel fitted with knives, cast into fire, and set over a concealed pit, surviving each. She was finally sentenced to be devoured by wild beasts in the arena. The tradition holds that the lions and bears would not attack her, and that she died when a she-bear wounded her foot. The sources place her martyrdom in 303 or 304.
