Priscus, Castrensis, Tammarus, Rosius, Heraclius, Secundinus, Adjutor, Mark, Augustus, Elpidius, Canion and Vindonius

Priscus, Castrensis, Tammarus, Rosius, Heraclius, Secundinus, Adjutor, Mark, Augustus, Elpidius, Canion and Vindonius are twelve hierarchs of North Africa, remembered together on 1 September and on 11 February in the Western calendar (new style). The century is the fifth, with a question mark.

According to the source, Priscus was a bishop in North Africa, and he and his priests were cast adrift in a boat by the Arian Vandals. They reached the south of Italy, where Priscus eventually became bishop of Capua. They are honoured as saints of the undivided Church, with no synodal canonization shown in the source.
