"At Palestrina (the old Praeneste, near Rome), the birth unto heaven of St. Agapitus, who, when only fifteen years old, was put to death after several torments by the stroke of the sword, thus winning the crown of immortality (275)" (Roman Martyrology).
Laetábitur justus in Dómino, et sperábit in eo: et laudabúntur omnes recti corde. * Exáudi, Deus, oratiónem meam, cum déprecor: a timóre inimíci éripe ánimam meam.
The just shall rejoice in the Lord, and shall hope in Him: and all the upright of heart shall be praised. * Hear, O God, my prayer when I make supplications to Thee: deliver my sould from the fear of the enemy.
(Psalm 63:11,2 from the Introit of Mass)
Laetetur Ecclesia tua, Deus, beati Agapiti Martyris tui confisa suffragiis: atque ejus precibus gloriosis, et devota permaneat, et secura consistat.
Let Thy Church rejoice, O God, in the intercession of the holy martyr Agapitus, in whose prayers she trusts; and through them may she ever devoutly serve Thee and abide in peace and safety.
