Next, she was subjected to a long imprisonment by Florius, prefect of Illyria. At last, on the island of Palmaria, she was fastened to posts with her hands and feet stretched apart, and a fire was enkindled about her. Thus she completed her martyrdom.

At Nicomedia, the sufferings of several thousand holy martyrs who on Christmas day were assembled at Mass. The Emperor Diocletian ordered the doors of the church to be shut and a fire to be prepared around the building. A tripod with incense was set before the door. Then a herald proclaimed that they who desired to escape the fire should come out and offer incense to Jupiter. When the Christians unanimously declared they would gladly die for the sake of Christ, the church was set on fire and they were burned alive. Thus, they were held worthy to be born in Heaven on the very day on which Christ was pleased to be born on earth for the salvation of the world.
