From Dom Guéranger's The Liturgical Year.
Beneventum offers to our homage twelve brothers martyrs, natives of Africa, who suffered in divers places, but whose bodies she glories in possessing. Let us unite in the prayer which the Church offers to God, in honour of this admirable group of heroes.
Collect
Fraterna nos, Domine, martyrum tuorum corona lætificet: quæ et fidei nostræ præbeat incrementa virtutum, et multiplici nos suffragio consoletur. Per Dominum.
May the fraternal crown of thy martyrs rejoice us, O Lord, and may it procure for our faith increase of virtue, and console us with multiplied intercession. Through our Lord, etc.
