Galaction hesitated before assenting. Learning of this, Episteme assented to become a Christian if it would seal the deal. It did, but once the wedding was complete, she learned that he intended to live chastely. Another woman might have been embittered, or sly, but another woman would not have been canonized. Episteme moved into a community of nuns while Galaction set himself up as a hermit.
When the Emperor Decius ordered a general persecution of Christians, Galaction got gaffled up. Learning of his arrest in a vision, Episteme went to stand by her man. They were confined together as they waited to be tortured and executed. Prisons being what they were, the Roman soldiers thought they'd pass the time by stripping Episteme and... they got no further. The fifty-three soldiers present were all blinded by her exposure. I expect that the subsequent interrogation was excessively brutal before the final beheading. At a minimum, it included vision scourging and the removal of hands and feet before the final decapitations. A monk named Eutolius, formerly a servant of Episteme's parents, buried the bodies and wrote about their joint martyrdom.
November 5 is also Guy Fawkes Day, of course. If you'd like a rant about him, you can find mine here.
