St. Photini, the Samaritan woman. You may know the story from the Bible, but Orthodoxy tells us what happened next. Her son, Victor, was a Roman general who defied Nero. She and her daughters traveled to Rome and spoke with Nero, trying to convert him to Christianity. Instead, he launched a persecution, during which she and her children were executed. Here, she is show with her eight children, all of them also saints.
This is St. Theodora, the wife of the Emperor Theophilus. She was an iconodule while her husband was an avowed iconoclast. After his death, she held a council that ended the iconoclast controversy once and for all. She also came up with the idea of the Sunday of Orthodoxy held every 2d Sunday of Great Lent.
