He was a deacon in Catana, Sicily. When Emperor Diocletian sent Duke Pentagure to Sicily to kill Christians, he did not find anyone because the few that were there were hiding. Then someone accused Euples of going with a book to secret Christians and reading it to them. When they brought him to court, they hung that book, the Holy Gospel, around his neck and threw him into prison. After 7 days of starvation, they handed him over to torture. They beat him heavily with iron rods, and he mocked them: "These torments are like cobwebs for me, find something worse." Then he opened the Gospel and read to the people from it. Then many converted to the faith of Christ. Saint Euplo was beheaded in 304. His miraculous relics are in the village of Vico della Batonia, near Naples.
