The Holy Prince Gleb of Vladimir, in Holy Baptism George, was the youngest son of the Holy Prince Andrew Bogolyubsky (Comm. July 4). Under the influence of pious parents, he grew up deeply religious and from the age of twelve led a secluded spiritual life. The parents did not hinder their son and even helped him in his spiritual growth. The Holy Prince was especially fond of reading holy books, revered the clergy, and was merciful to everyone. Despite his young age, he chose for himself the feat of strict fasting and prayer vigil. The blessed Prince Gleb died in 1174, at the age of nineteen.
His incorruptible relics were preserved and became famous for miracles. In 1238, during Batu's invasion of the Russian land, the Tatars set fire to the cathedral in Vladimir. Bishop Mitrofan, Grand Duchess Agafia, wife of Grand Duke George Vsevolodovich (+ 1238), and many residents of Vladimir, who had closed themselves in the cathedral church, were burned down in this fire. However, the fire did not even touch the tomb of the blessed Prince Gleb. In July 1410, Vladimir was attacked by the Tatars. Having plundered the city, they began to plunder the church treasures of the cathedral, killing the cathedral sacristan Patrikios. Believing that there were treasures hidden in the tomb, they wanted to break it up. As soon as the Tatars touched the stone coffin of the holy Prince Gleb, flames came out of it, and the Tatars left the city in fear.
Through the prayers of the holy Prince, the city was saved from the invasion of the Polish-Lithuanian invaders in 1613.
The celebration of the blessed Prince Gleb was established in 1702, in the same year a service was written, and a little later a life. The relics rest in the Assumption Cathedral in Vladimir. In 1774, the south aisle of the cathedral was consecrated in honor of his name. The blessed Prince Gleb is revered as a special patron and defender of the city of Vladimir.
