From Dom Guéranger's The Liturgical Year.
A holy priest named Nicomedes is honoured today. The virgin martyr St. Felicula, whose body he had buried, obtained for him in return the palm of martyrdom. Let us, together with the Church, implore his protection.
Prayer
Adesto, Domine, populo tuo: ut beati Nicomedis martyris tui merita præclara suscipiens, ad impetrandam misericordiam tuam semper ejus patrociniis adjuvetur. Per Dominum.
Attend to thy people, O Lord, that having recourse to the splendid merits of blessed Nicomedes, thy martyr, they may ever be assisted by his patronage for obtaining thy mercy. Through &c.
