Saint Marcian was born in Rome but was educated in Constantinople. After the death of his parents, he used his inheritance to build churches and help the poor. The Patriarch was impressed by his way of life, ordained him, and made him treasurer of the Church of Constantinople. He had no possessions of his own, even an extra set of clothes, and God granted him the gift of wonderworking. He reposed about the year 473. His feast is celebrated on January 10.
