Nereus Achilleus Domitilla and Pancras Saint
Nereus, Achilleus, Domitilla, and Pancras are venerated as martyrs of the Roman Catholic Church.In the present General Roman Calendar, revised in 1969, Saints Nereus and Achilleus (together) and Saint Pancras have distinct celebrations (optional memorials) on 12 May. Saint Domitilla is not included in the revised calendar, because the liturgical honours once paid to her "have no basis in tradition".The Tridentine Calendar had on 12 May a joint feast (semidouble rank) of Nereus, Achilleus and Pancras. The name of Domitilla was added in 1595. The joint celebration of Nereus, Achilleus, Domitilla and Pancras continued with that ranking (see General Roman Calendar of 1954) until the revision of 1960, when it was reclassified as a third-class feast (see General Roman Calendar of 1960).
