Saint Juliana, a martyr from Nicomedia, is remembered for being the sole Christian in her family during a time when pagan beliefs predominantly shaped society. According to ancient accounts, her father, of African descent, was a devoted worshipper of pagan deities. To cement her family's pagan lineage, he arranged for her to marry a pagan named Evilazius, who held the position of city prefect. Juliana was willing to marry Evilazius only if he would convert to Christianity, which enraged him and led to her being accused and brought to trial for her faith.

Despite facing severe threats and torture, Juliana stood firm in her belief and refused to renounce her Christian faith, which ultimately led to her being sentenced to death by beheading in Nicomedia under the reign of Emperor Maximian in the year 305. This story highlights the trials faced by early Christians who labored under oppressive pagan regimes and illustrates the personal sacrifices made for faith in a time of religious intolerance.

Her remains were initially transported from Nicomedia to Puteoli, then to Guma, and finally in 1207, to Naples, where they are venerated today. Saint Juliana's legacy lives on, especially in Naples and other regions where her story serves as a reminder of the faith's endurance through persecution.
