From Dom Guéranger's The Liturgical Year.
Let us go in spirit to Rome, and direct our steps towards the ancient church on the Coelian Hill, which bears the name of the Four crowned Martyrs. There are few Saints whose Acts have been more disparaged “by a superficial criticism ignorant of archeological science,” such as that of the 16th, 17th, and 18th centuries. But now "the history and traditions relating to the august monument on the Coelian have been restored to honour by learned men and antiquaries, whom no one could accuse of superstition, or of a blind credulity with regard to mediaeval legends.[1] Such is the unanswerable decision of the Commandant de Rossi. Let us, then, with the holy Liturgy, offer our homage and prayers to the titular Saints of this venerable church, who once held offices of trust in the empire; and let us not forget those other Martyrs, the five sculptors, who like the former preferred death to infidelity, and now share the glory of their tomb.
Prayer
Praesta, quaesummus omnipotens Deus: ut, qui gloriosos Martyres fortes in sua confessione cognovimus, pios apud te in nostra intercessione sentiamus. Per Dominum.
Grant we beseech thee, O Almighty God, that we who know thy glorious Martyrs to have been strong in their confession of thee, may experience their compassion by their interceding for us with thee. Through our Lord.
