Potamiæna, one of the most celebrated of the martyrs that suffered under Severus, is made by Rufinus a disciple of Origen, but Eusebius does not say that she was, and indeed, in making Basilides the seventh of Origen’s disciples to suffer, he evidently excludes Potamiæna from the number. Quite a full account of her martyrdom is given by Palladius in his Historia Lausiaca, chap. 3 (Migne’s Patr. Gr. XXXIV. 1014), which contains some characteristic details not mentioned by Eusebius. It appears from that account that she was a slave, and that her master, not being able to induce her to yield to his passion, accused her before the judge as a Christian, bribing him, if possible, to break her resolution by tortures and then return her to him, or, if that was not possible, to put her to death as a Christian. We cannot judge as to the exact truth of this and other details related by Palladius, but his history (which was written early in the fifth century) is, in the main at least, reliable, except where it deals with miracles and prodigies (cf. the article on Palladius of Helenopolis, in the Dict. of Christ. Biog.).
