The Armatia Icon of the Mother of God was in Constantinople at the Armatian monastery. The place where the monastery was located, was called “Armation” or “of the Armatians” and received its name from the military magister Armatias, nephew of the tyrant Basiliscus, and a contemporary of the emperor Zeno (474-491).
The celebration of the wonderworking icon was established to commemorate deliverance from the Iconoclast heresy. The Seventh Ecumenical Council of 787 drew up dogmatic definitions about icon veneration based on Holy Scripture and Church Tradition.
The Armatia Icon of the Most Holy Theotokos is commemorated twice during the year, on July 21 and August 17.
