According to legend, Eugenia came with her parents from Rome to Alexandria around 185, at the time of Emperor Commodus, her father Philip became the Roman prefect there. She was scientifically educated and came to the Christian faith by reading the letters of the Apostle Paul. Supported by the eunuchs Protus and Hyacinthus, she entered a men’s monastery in men’s clothes and became abbot there at a young age. When a woman wanted to seduce the abbot, she was rebuked by him, whereupon Eugenius was accused of fornication by the rejected and sued the prefect. To him – her father – she revealed her true identity and then won her parents for Christianity. She could no longer stay in the monastery, so she went back to Rome with her family and was beheaded in the persecution of Christians by the emperor Valerian and Gallienus, with her her father and the two eunuchs died.
