This miraculous appearance of the Mother of God occurred in the mid-tenth century in Constantinople, in the Blachernae church where her robe, veil, and part of her belt were preserved after being transferred from Palestine in the fifth century.

On Sunday, October 1, during the All Night Vigil, when the church was overflowing with those at prayer, the Fool-for-Christ Saint Andrew (October 2), at the fourth hour, lifted up his eyes towards the heavens and beheld our most Holy Lady Theotokos coming through the air, resplendent with heavenly light and surrounded by an assembly of the Saints. Saint John the Baptist and the holy Apostle John the Theologian accompanied the Queen of Heaven. On bended knees the Most Holy Virgin tearfully prayed for Christians for a long time. Then, coming near the Bishop’s Throne, she continued her prayer.
