Martyr Evilasius (died 311) was a pagan priest who tortured a 13-year-old girl who later became Saint Fausta. Realizing her courage, he himself converted to Christianity, an act punishable by death since the people of Cyzicus did not want even one of their people to convert to any religion other than their own.[1]
