The Vision of the Protection of the Theotokos
Andrew's defining spiritual encounter took place in the Blachernae church of Constantinople while the city was surrounded by enemy troops, identified in some sources as Muslim Arabs. By Sacred Tradition the apparition occurred on Sunday at dawn, October 1, when Andrew saw the dome of the church open and the Virgin Mary enter, moving in the air above him, glowing and surrounded by angels and saints.
The Virgin Mary prayed fervently for all faithful Christians throughout the world, petitioning her Son Jesus Christ to accept the prayers of those seeking her protection, and spread her veil (omophorion) over the people in the church as a sign of divine intercession. Andrew turned to his disciple Epiphanius and asked, in effect, whether he too saw the Holy Theotokos praying for all the world; Epiphanius confirmed the vision with amazement.
After the vision, Constantinople was saved when its attackers retreated. The deliverance attributed to this event inspired the feast of the Protection of the Theotokos.
Historical Context and Legacy
The Primary Chronicle of St. Nestor the Chronicler records that the inhabitants of Constantinople invoked the Theotokos's intercession during an attack by a large Rus' army (the Rus' Khaganate, still pagan at the time). The feast commemorates the subsequent destruction of this fleet, though alternative traditions hold that the outcome was the conversion of the Rus' to Christianity rather than a military defeat.
Veneration of the Intercession (Pokrov) became firmly established in Rus', Belarus, Russia, and Ukraine by the 12th century, and grew into a feast of profound significance within Slavic Orthodox traditions.
Dating and Sources
Scholars debate when Andrew actually lived. According to the Life of Andrew the Fool, he lived in the fifth century during the reign of the Byzantine emperor Leo I (457-474). Some historians, however, place him in the ninth to tenth centuries during the reign of Leo VI the Wise, citing anachronisms in the text.
More than 110 complete and fragmentary Greek manuscripts containing various editions of the Life of Andrew the Fool have survived. The oldest is a fragment of a manuscript dating to the second half of the 10th century.
