Julia was a noble virgin of Carthage, who, when the city was taken by Genseric in 439, was sold as a slave to a pagan merchant of Syria named Eusebius. Under the most mortifying employments of her station, by cheerfulness and patience she found a happiness and comfort which the world could not have afforded. All the time she was not employed in her master's business was devoted to prayer and reading books of piety. Her master, who was charmed with her fidelity and other virtues, thought proper to carry her with him on one of his voyages to Gaul.
Having reached the northern part of Corsica, he cast anchor, and went on shore to join the pagans of the place in an idolatrous festival. Julia was left at some distance, because she would not be defiled by the superstitious ceremonies which she openly reviled. Felix, the governor of the island, who was a bigoted pagan, asked who this woman was who dared to insult the gods. Eusebius informed him that she was a Christian, and that all his authority over her was too weak to prevail with her to renounce her religion, but that he found her so diligent and faithful he could not part with her. The governor offered him four of his best female slaves in exchange for her. But the merchant replied, "No; all you are worth will not purchase her; for I would freely lose the most valuable thing I have in the world rather than be deprived of her."
