The account of the appearance is to be found in the Life of St. Andrew "the Fool in Christ" (died 956). It is at the church of Blachernes [in Constantinople], where the robe, the veil and part of the girdle of the Holy Virgin are preserved, that the appearance occurred. During the office of the vigil, about four in the morning, St. Andrew and his disciple Epiphanius saw a majestic woman advancing towards the ambo, supported by St. John the Baptist and St. John the Evangelist, and accompanied by several saints. On reaching the center of the church, the Mother of God knelt down and remained long in prayer, her face bathed in tears. When she had prayed yet again before the altar, she took off the shining veil which enveloped her and, holding it above her head, extended it over all the people present in the church. Andrew and Epiphanius alone were able to see the appearance of the Mother of God and her veil which shone like the glory of God, but all who were present felt the grace of her protection. This invisible protection of the Mother of God, interceding with her Son for the whole universe, protection that St. Andrew could contemplate in the form of a veil covering the faithful, constitutes the central idea of the festival of October 1st: "The Virgin is today present in the church: with the choirs of the saints she prays to God invisibly for us. Angels and bishops prostrate themselves, apostles and prophets rejoice: for the Mother of God intercedes for us before the eternal God."
The Mother of God is seen standing on a small cloud, hovering in the air above the faithful. She has both arms outstretched in a gesture of supplication, expressing her prayer of intercession. Two angels hold by either end a great veil which billows in the form of a vault over the Mother of God. The procession of saints which surrounded the Queen of the Heavens at the time of her appearance is represented by two groups of apostles and prophets with St. John the Forerunner. On his scroll: "Repent, for the Kingdom of God is near."
To the right of the ambo, two persons in the foreground are detached from the crowd of the faithful. They are St. Andrew and St. Epiphanius, the witnesses of the appearance of the Mother of God. St. Andrew is turned towards his disciple showing him the appearance with a gesture of the right arm extended towards the Mother of God.
