"The Icon of the Savior Not-Made-By-Hands was depicted on the banners of the Russian army, and His image was placed over the gates of fortresses. Soldiers always saw in it their patron, and civilians—their defender and Savior.”
During the time of the earthly ministry of the Savior, Abgar, ruler in the Syrian city of Edessa, was afflicted with leprosy. Reports of the great miracles performed by the Lord extended throughout Syria (Matt. 4:24) and as far as Arabia at this time. Although not having seen the Lord, Abgar believed in him and wrote a letter requesting Christ to come and heal him. Abgar sent his court painter, Ananias, with this letter to Palestine telling him to paint an image of the Divine Teacher. Ananias was not able go to near Christ because of the great many people listening to his preaching. He attempted to produce an image of the Lord Jesus Christ from afar, but could not. The Lord called Ananias and promised to send his disciple in order to heal Abgar from the leprosy and instruct him in salvation. Then the Lord called for water and a towel. He wiped His face with the towel, and on it was His Divine Image.
The Savior sent the towel and a letter to Edessa back with Ananias. With thanksgiving Abgar received the sacred objects and started healing. He continued healing until the arrival of the disciple Thaddeus, Apostle of the 70. The Apostle preached the Gospel and baptized the Abgar and all living in Edessa.
Having written on the Image Not-Made-By-Hands the words, Christ-God, everyone trusting in Thee will not be put to shame, Abgar adorned it and placing it over gates of the city. For many years it was venerated by those who passed through the gates. Edessa, a great-grandson of Abgar, fell into idolatry and was determined to remove the image. In a vision, the Lord ordered the Bishop of Edessa to conceal the image. The bishop and his clergy at night, blocked up the niche with clay tablets and bricks inclosing with it a lit lampada. Many years passed by and the inhabitants forgot about the Holy Object.
In the year 545, the Persian King Chroses I, besieged Edessa, and all seemed hopeless. But Bishop Evlavios was commanded by a vision of the Theotokos to get from the enclosed niche the image with which to save the city from the adversaries. Dismantling the niche, the Bishop found the Holy Image; before it burned the lampada and on the clay tablets, with which the niche had been enclosed, was a similar image. After preceding with the Cross and the Image Not-Made-By-Hands around the walls of the city, the Persian army miraculously departed. In 630, Edessa was seized by Arabs; but they did not hinder veneration of the Image Not-Made-By-Hands. In 944 the Emperor Constantine Porphyrogenitus (912-59) requested that the Image be brought to the Capital of the Orthodox. With great honor the Image of the Savior Not-Made-By-Hands was brought by the clergy to Constantinople. On August 16 the Image of the Savior was placed in the Pharos Church of the Most-Holy Theotokos.
