was appointed bishop of Antioch after his predecessor Paul of Samosata was deposed by two Antiochene synods (264 and 268 ce). His episcopate was probably brief (268–271?). Since Paul was unwilling to step down, Domnus was able to occupy the church building only after Emperor Aurelian, who had been asked for a ruling, decreed that those who were in epistolary contact with the bishops in Rome and Italy were legally entitled to it (Eus. Hist. eccl. VII 30.18–19).
