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.
