Potamiana, or Potamiaena (d. ca. 205 AD), is venerated as a Christian saint and martyr. According to her legend, she, along with her mother Marcella, had been condemned to be sunk by degrees in a cauldron of boiling pitch at Alexandria, Egypt. She was also threatened with being handed over to gladiators to be raped.
After Potamiana had been sentenced to death, Basilides, an officer of the court, led her to execution; on the way, he protected her against the insults of the mob. In return for his kindness Potamiana promised him not to forget him with her Lord when she reached her destination.
Soon after Potamiana's death Basilides was asked by his fellow-soldiers to take a certain oath; on answering that he could not do it, as he was a Christian, at first they thought he was jesting, but seeing he was in earnest they denounced him and he was condemned to be beheaded.
While waiting in jail for his sentence to be carried out some Christians (Origen being possibly one of them) visited Basilides and asked him how he happened to be converted; he answered that three days after her death, Potamiana had appeared to him by night and placed a crown on his head as a pledge that the Lord would soon receive him into his glory. Basilides was then baptized and the next day he was beheaded.
Potamiana appeared to many other persons at that time, calling them to faith and martyrdom (Eusebius, Church History VI, iii-v). To these conversions, Origen, an eyewitness, testifies in his Contra Celsum (I, 46; P. G., XI, 746). The description of the episode of intercession of Potamiana on behalf of Basilides, narrated in Eusebius’ text, constitutes one of first documents that concerns the intercession of saints.
Six Christians, students of Origen, were martyred at the same time. Eusebius describes the martyrdom of this group:
The first of thee was Plutarch... After Plutarch, the second martyr among the pupils of Origen was Serenus, who gave through fire a proof of the faith which he had received. The third martyr from the same school was Heraclides, and after him the fourth was Hero. The former of these was as yet a catechumen, and the latter had but recently been baptized. Both of them were beheaded. After them, the fifth from the same school proclaimed as an athlete of piety was another Serenus, who, it is reported, was beheaded, after a long endurance of tortures. And of women, Herais died while yet a catechumen, receiving baptism by fire, as Origen himself somewhere says.

The martyrdoms of Basilides, Potamiana, Marcella and six disciples of Origen are commemorated in the Martyrologium Hieronymianum on June 28. The Roman Martyrology commemorates only Basilides on June 30.
