Saints Primus and Felician were brothers who suffered martyrdom about the year 297 during the Diocletian persecution. The "Martyrologium Hieronymianum" gives under June 9 the names of Primus and Felician who were buried at the fourteenth milestone of the Via Nomentana. They were evidently from Nomentum. This notice comes from the catalogue of Roman martyrs of the fourth century.
Their feast day is 9 June. In the past they were also included in the General Roman Calendar, but because of the limited worldwide interest in them, it was decided in 1969 to leave to individual dioceses the decision whether to include them in their local calendars.
A Bavarian tradition holds that Sts Primus and Felician were Roman legionaries who became missionaries in the region of Chiemgau, where Primus found in a forest a fountain with curative properties. The two brothers preached the Gospel there and cured the sick by virtue of their prayers and the virtue of the source. When they returned to Italy, they were martyred under Diocletian. The fountain, known as the Fountain of Saint Primus, can still be seen at Adelholzen, an area of hot springs where a chapel constructed in 1615 can be found, dedicated to these saints, who are much venerated in the area.
During the 9th century, the cult of Saint Faith was fused with that of Caprasius of Agen and Alberta of Agen, also associated with Agen. Caprasius' cult in turn was fused with that of Primus and Felician, who are called Caprasius' brothers. One legend states that during the persecutions of Christians by the prefect Dacian, Caprasius fled to Mont-Saint-Vincent, near Agen. He witnessed the execution of Faith from atop the hill. Caprasius was condemned to death, and was joined on his way to execution by Alberta, Faith’s sister, and two brothers, named Primus and Felician. All four were beheaded.
Acts
Their "Acts" relate that Sts Felician and Primus were brothers and patricians who had converted to Christianity and devoted themselves to caring for the poor and visiting prisoners. Arrested, they both refused to sacrifice to the public gods. They were imprisoned and scourged. They were brought separately before the judge Promotus, who tortured them together and endeavored to deceive them that the other had apostatized by offering sacrifice. This had no effect on the brothers, and the two were subsequently beheaded under the Emperor Diocletian at Nomentum. St Primus was eighty years old at the time of his death. A church was built over their tombs on the Via Nomentana.
