(Saints) Martyrs (June 28) (3rd century) Martyrs of Alexandria in Egypt in the persecution under Septimius Severus (A.D. 202). Eusebius describes them as being disciples of Origen, then at the beginning of his career. They were variously tortured before execution, and most of them burned alive. Among those who thus perished the best known is Saint Potamioena, a maiden who was tied to the same stake and died in the same Are with her mother, Saint Marcella.
