The Martyrs Marcian and Martyrius, Notaries of Constantinople served in a Constantinople cathedral. Marcian was a reader and Martyrius a subdeacon. They both performed in the capacity of notaries, i.e. secretaries, for Patriarch Paul the Confessor (November 6).

Arian heretics expelled and secretly executed the righteous Patriarch Paul. His throne was given to the heretic Macedonius. The heretics attempted to entice Saints Marcian and Martyrius over to their side by flattery. They offered them gold and promised to consecrate them as archbishops, but all the efforts of the Arians were in vain.
