Anyone who has studied the history of the early church has likely heard of Perpetua and Felicity and perhaps has read the classic text, The Passion of St. Perpetua, St. Felicitas, and their Companions. I think I read that account in college and then again in seminary.
The saints, martyred in 203, are honored today of Roman Catholic and Protestant calendars and on February 1 on the Orthodox calendar. The Orthodox site has this account:
"Perpetua, Felicity, Saturus, Saturninus, Secundus and Revocatus were all young catechumens living near Carthage. Perpetua was of noble birth; Felicity (Felicitas) was her slave. All were arrested under Emperor Valerian's persecution and sent to Carthage. Perpetua had a young child still at the breast, which she asked to take with her.
"The holy martyrs appeared before the tribunal and joyfully received their sentence of condemnation to be thrown to the wild beasts in the arena. Felicity, who was eight months pregnant, was concerned that her martyrdom might be postponed because of her pregnancy, but at the prayers of her friends, she went into labor three days before the games. As she groaned in labor, a jailer mocked her, telling her that the pain she felt was nothing to the pain that she would feel in the arena. The Saint replied, 'Here I suffer for myself; then there will be Another with me, who will suffer with me; and my sufferings will be for Him!' When she gave birth, she entrusted her newborn child to the care of a Christian couple and prepared for her end.
"On the day of the games, the brothers and sisters in Christ entered the arena together. The men were soon killed by the beasts, but Perpetua and Felicity, though mauled, remained alive. The impatient persecutors ordered that they be beheaded. Walking to the center of the arena, the two spiritual sisters exchanged the kiss of peace and gave up their souls to God."
