According to the hagiography, Saint Martyr Alexandra, the wife of Emperor Diocletian, was a secret Christian. Seeing the steadfastness of Saint George during his sufferings, she decided to openly confess her faith. Alexandra approached Saint George and, falling at his feet, declared her Christian faith. Diocletian, enraged by this, sentenced her to death. Saint Alexandra bravely accepted the sentence and, prayerfully looking up to heaven, went to her execution. On the way, tired, she asked the soldiers to allow her to rest and, leaning against the wall, quietly passed away on May 4, 303. Her memory is celebrated on May 6.
According to historical sources, Diocletian's wife was Prisca, who also professed Christianity. In 303, during the persecutions, she was forced to renounce her faith. After Diocletian's renunciation, Prisca and her daughter Valeria were persecuted and executed in 315. There is a possibility that Prisca could have received the name Alexandra after baptism, but this is not confirmed by ancient hagiographies.
In another hagiography, it is mentioned that after Diocletian's renunciation, power passed to Maximian Galerius, a pagan, who was the husband of Saint Valeria, daughter of Saint Alexandra. Valeria, raised in Christian piety, was exiled to Syria. After the death of Maximin, mother and daughter arrived in Nicomedia, where they hoped for the mercy of Emperor Licinius, who, despite the signed Edict of Milan, remained an enemy of Christianity. Licinius ordered the execution of Saint Alexandra and Valeria, and their bodies were thrown into the sea.
