"St. Agnes (291?–304?), saint and virgin martyr of Rome, one of the most popular and universal of saints whose name is commemorated daily in the canon of the Mass. At the age of 12 or 13 she consecrated her virginity to God. She is noted for her purity, her youthfulness, and her heroism in the face of persecution.

Agnes, whose name means “chaste” in Greek, was a beautiful young girl of wealthy family and therefore had many suitors of high rank. Details of her story are unreliable, but legend holds that the young men, slighted by Agnes' resolute devotion to religious purity, submitted her name to the authorities as a follower of Christianity. The governor, following an edict against Christians issued in 303 by the Roman emperor Diocletian, threatened the young girl with torture. The threats did not intimidate the steadfast Agnes , however, and the enraged official sent her to a house of prostitution. Approaching her, the brothel's patrons would be seized with such awe at the holy sight of the girl that they could not touch her. One brazen young man remained undeterred, but as he neared her he was struck blind and fell to the ground; Agnes later restored his sight with prayer.  The governor, incensed by her youthful defiance, sentenced Agnes to an untimely death. It is not known whether the execution was by beheading or by the piercing of the throat, but the story tells of her ready submission to the sentence by offering herself to receive the death blow. According to St. Ambrose, one of her chroniclers, she “went to the place of execution more cheerfully than others go to their wedding.”

Agnes was buried beside the Via Nomentana in Rome. In about 354 Constantina, the daughter of Constantine, the first Christian Roman emperor, honored her by erecting a basilica over her grave. Remaining inscriptions in the church attest that Agnes was “a virgin” and “victorious.” Her skull was removed before the 9th century and placed in the Sancta Sanctorum of the Lateran Palace. An examination of the skull in 1903 confirmed the girl's age of 12 or 13 at death. Pope Pius X gave the relic to the Church of Santa Agnese in Piazza Navona in Rome.

Because of her innocence and also because the name Agnes closely resembles the Latin word for lamb (agnus) the saint is usually pictured in art with a lamb in her arms or near her feet. Each year on Agnes' feast day (January 21), two white lambs are blessed and their sheared wool woven into the pallia sent to new archbishops throughout the world."
