Little is known about the life of St. Philomena. However, it is believed she was a Greek princess who became a virgin martyr and died at 13-years-old.
Remains of a young lady were discovered in May 1802 at the Catacombs of Priscilla on the Via Salaria Nova with three tiles reading "Peace be to you, Philomena."
All that is known about St. Philomena's life comes from a Neapolitan nun's vision. Sister Maria Luisa di Gesu claims St. Philomena came to her and told her she was the daughter of a Greek king who converted to Christianity. When Philomena was 13-years-old, she took a vow of consecrated virginity.
After her father took his family to Rome to make peace, Emperor Diocletian fell in love with Philomena. When she refused to marry him, she was subjected to torture.
St. Philomena was scourged, drowned with an anchor attached to her, and shot with arrows. Each time she was attacked angels took to her side and healed her through prayer.
Finally, the Emperor had Philomena decapitated. According to the story, her death came on a Friday at three in the afternoon, the same as Jesus.
Two anchors, three arrows, a palm symbol of martyrdom, and a flower were found on the tiles in her tomb, interpreted as symbols of her martyrdom.
The nun's account states Philomena was born on January 10 and was killed on August 10.
Devotion for Philomena began to spread once her bones were exhumed and miracles began to occur. Canon Francesco De Lucia of Mugnano del Cardinale received relics of St. Philomena and had them placed in the Church of Our Lady of Grace in Mugnano, Italy.
Soon after her relics were enshrined, cancers were cured, wounds were healed and the Miracle of Mugnano, when Venerable Pauline Jaricot was cured of a severe heart issue overnight, were all attributed to St. Philomena.
Other Saints began to venerate Philomena and attributing miracles in their lives to the young martyr, including St. John Marie Vianney and St. Peter Louis Marie Chanel.
Although controversy sometimes surrounds the truth behind St. Philomena's life and sainthood, many believers all around the world continue to see her as a miraculous saint, canonized in 1837.
St. Philomena is the patron saint of infants, babies, and youth. She is often depicted in her youth with a flower crown, a palm of martyrdom, arrows, or an anchor.
Her feast day is celebrated on August 11.

Saint Philomena revealed Her story to three people who did not know one another and who resided in different parts of Italy. These private revelations unveiled the story of Saint Philomena’s life in great detail and were amazingly identical accounts.
    One of the most well-known recipients of this revelation was the Foundress of the Oblates of Our Lady of Sorrows, Mother Maria Luisa di Gesù, a Dominican Tertiary.
    On August 3, 1833, after having received the Eucharist, the nun Maria was praying before Saint Philomena’s statue and at that moment felt a strong desire to know the true date of the Saint’s martyrdom. August 10 was the day St. Philomena’s relics had arrived in Mugnano, Italy. This date was significant to the people of Mugnano, but not to those who lived elsewhere. As Maria contemplated this, she closed her eyes and suddenly a gracious and gentle voice came from the direction of the statue, saying:
    "Dear Sister, August the tenth was the day of my rest, my triumph, my birth into Heaven, my entering into the possession of such eternal goods as the human mind cannot possibly imagine. That is why my Heavenly Spouse disposed, by His most high decrees that my coming to Mugnano should be on the day which had seen my coming to Heaven! He prepared so many circuмstances which should make my arrival at Mugnano glorious and triumphant; giving joy to all the people, even though the priest who brought me had absolutely decided that my translation should take place on the fifth of the month very quietly in his own house. My omnipotent Spouse impeded him with so many obstacles that the priest, although he did all he could to carry out his plan, could not do so. And so it came about that the said translation was made on the tenth, the day of my feast in Heaven."
    Mother Maria was overwhelmed by this and thought she had fallen as prey to this illusion. She took refuge in the Sacrament of Penance, confessing the whole event to her spiritual director. He was not so hasty in disposing of the matter. He proceeded to write to Don Francesco de Lucia Link Out in Mugnano and inquired about the truth of whether or not he originally intended to have the translation on August 5. Don Francesco’s reply confirmed that he indeed encountered many obstacles which detained him from carrying out his plan to arrive in Mugnano on the fifth.
