The old guidebooks to the tombs of the Roman martyrs make mention, in connection with the catacomb of Saints Peter and Marcellinus on the Via Labicana, of the Four Crowned Martyrs (Quatuor Coronati), at whose grave the pilgrims were wont to worship. One of these itineraries, the “Epitome libri de locis sanctorum martyrum”, adds the names of the four martyrs (in reality five): “IV Coronati, id est Claudius, Nicostratus, Simpronianus, Castorius, Simplicitus”. These are the names of five martyrs, sculptors in the quarries of Pannonia (now a part of Austria-Hungary, south-west of the Danube), who gave up their lives for their Faith in the reign of Diocletian. The Acts of these martyrs, written by a revenue officer named Porphyrius probably in the fourth century, relates of the five sculptors that, although they raised no objections to executing such profane images as Victoria, Cupid, and the Chariot of the Sun, they refused to make a statue of Æsculapius for a heathen temple. For this they were condemned to death as Christians. They were put into leaden caskets and drowned in the River Save. This happened towards the end of 305. The foregoing account of the martyrdom of the five sculptors of Pannonia is substantially authentic; but later on a legend sprang up at Rome concerning the Quatuor Coronati, according to which four Christian soldiers (cornicularii) suffered martyrdom at Rome during the reign of Diocletian, two years after the death of the five sculptors. Their offence consisted in refusing to offer sacrifice to the image of Æsculapius. The bodies of the martyrs were interred at Saint Sebastian and Pope Melchiades at the third milestone on the Via Labicana, in a sandpit where rested the remains of others who had perished for the Faith. Since the names of the four martyred soldiers could not be authentically established, Pope Melchiades commanded that, the date of their death (8 November) being the same as that of the Pannonian sculptors, their anniversary should be celebrated on that day, under the names of Saints Claudius, Nicostratus, Symphorianus, Castor, and Simplicius. This report has no historic foundation. It is merely a tentative explanation of the name Quatuor Coronati, a name given to a group of really authenticated martyrs who were buried and venerated in the catacomb of Saints Peter and Marcellinus, the real origin of which, however, is not known. They were classed with the five martyrs of Pannonia in a purely external relationship. Numerous manuscripts on the legend as well as the Roman Martyrology give the names of the Four Crowned Martyrs, supposed to have been revealed at a later date, as Secundus, Severianus, Carpoforus, and Victorius. But these four martyrs were not buried in Rome, but in the catacomb of Albano; their feast was celebrated on 7 August, under which date it is cited in the Roman Calender of Feasts of 354. These martyrs of Albano have no connection with the Roman martyrs described above. Of the four Crowned Martyrs we know only that they suffered death for the Faith and the place where they were buried. They evidently were held in great veneration at Rome, since in the fourth and fifth century a basilica was erected and dedicated in the Caelian Hill, probably in the neighbourhood of spot where tradition located their execution. This became one of the titular churches of Rome, was restored several times and still stands. It is first mentioned among the signatures of a Roman council in 595. Pope Leo IV ordered the relics removed, about 850, from the Via Labicana to the church dedicated to their memory, together with the relics of the five Pannonian martyrs, which had been brought to Rome at some period now unknown. Both group of martyrs are commemorated on 8 November.
