Well, the Feast of St. Philomena is traditionally August 11. Before anyone debates, it is still observed liturgically in those places where special veneration is present or in places where she is still a patron. The rector of the Shrine in Italy made this clarification. So, although it is late, here is a Novena for St. Philomena.
NOVENA IN HONOR OF ST. PHILOMENA VIRGIN & MARTYR
O St. Philomena, behold me before the bright throne whereon the August Trinity hath set thee, wearing thy double crown of virginity and martyrdom; behold, I lift suppliant hands to thee. Even the most cruel sufferings could not diminish the devotion of thy generous heart to the Celestial Lover Who was thy joy. And now thy Lord, to recompense those sufferings, wills to glorify thee by the mightiness of thine intercession.
Therefore it is to thee, O illustrious Martyr, that I lift my suppliant hands. Ah! from the heights of the heavenly country, deign to cast a glance upon me, thy humble client. O pure Virgin, O Holy Martyr, solace me in suffering and temptation, sustain me in trial and persecution, assist me in danger, and above all at the awful hour of death, when I shall have to combat all the powers of Hell, pray for me in that final moment upon which my eternity hangs. Amen
Jesu, coróna Vírginum
(Anon. Hymn from the Vespers of a Virgin Martyr)
Jesu, coróna Vírginum,
Quem Mater illa cóncipit
Quæ sola Virgo párturit,
Hæc vota clemens áccipe :
Qui pergis inter lília
Septus choréis Vírginum,
Sponsus decórus glória
Sponsísque reddens præmia.
Quocúmque tendis, Vírgines
Sequúntur, atque láudibus
Post te canéntes cúrsitant,
Hymnósque dulces pérsonant ;
Te deprecámur súpplices,
Nostris ut addas sénsibus
Nescíre prorsus ómnia
Corruptiónis vúlnera.
Virtus, honor, laus, glória
Deo Patri cum Fílio,
Sancto simul Paráclito,
In sæculórum sæcula. Amen.
Oremus: Deus, qui inter cétera poténtiæ tuæ mirácula, etiam in sexu frágili victóriam martýrii contulísti: concéde propítius: ut, qui beátæ Philuménæ Vírginis et Mártyris tuæ natalítia cólimus, per ejus ad te exémpla gradiámur. Per Dóminum nostrum, Jesum Christum, Fílium tuum, qui tecum vivit et regnat, in unitáte Spíritus Sancti Deus, per ómnia sæcula sæculórum. Amen.
