Catherine, virgin of Alexandria, devoted herself to the pursuit of knowledge; at the age of eighteen, she surpassed all her contemporaries in science. Upon seeing how the Christians were being tortured, she went before Emperor Maximin (311-313), upbraided him for his cruelty, and with convincing reasons demonstrated the need of Christian faith in order to be saved. Astounded by her wisdom, the Emperor ordered her to be kept confined, and having summoned the most learned philosophers, promised them magnificent rewards if they could confound the virgin and turn her from belief in Christ. Far from being successful, a considerable number of the philosophers were inflamed by the sound reasons and persuasiveness of Catherine's speech with such a love for Jesus Christ that they declared themselves willing to offer their lives for the Gospel.
Then the Emperor attempted to win her by flattery and by promises, but his efforts proved equally fruitless. He ordered her whipped with rods, scourged with leaden nodules, and then left to languish eleven days without food in prison. The Emperor's wife and Porphyrius, general of the army, visited Catherine in prison; her words brought both to Christ and later they too proved their love in blood. Catherine's next torture consisted of being placed upon a wheel with sharp and pointed knives; from her lacerated body prayers ascended to heaven and the infernal machine fell to pieces. Many who witnessed the miracle embraced the faith. Finally, on November 25 Christ's servant was beheaded (307 or 312). By the hands of angels her body was carried to Mt. Sinai, where it was interred in the convent which bears her name.
