The Earlier Martyrs Beneath the Crypt
Beneath the chamber holding the four named martyrs, excavators found the bone fragments of two further men, aged roughly forty-five to fifty. These are thought to have died in an earlier wave of persecution, that of the Emperor Decius (249-251), and to have been reinterred at the site around 370-380, when the upper martyrion was built above them.
The find situated the four named martyrs within a longer history of Christian witness in Scythia Minor. An inscribed piece of sandstone recovered at the site bore the words 'here and there the blood of the martyrs', and an extended Greek synaxarion tradition associates the wider region of Old Noviodunum with additional Christians who died there, though only the four are documented at this particular burial.
