Holy Prince Gleb of Vladimir, named George in holy Baptism, was a younger son of the holy Prince Andrew Bogoliubsky (July 4). Under the influence of his pious parents he grew up with a deep faith, and from twelve years of age he led a solitary spiritual life. The parents did not hinder their son and even assisted him in spiritual growth. The prince especially loved the reading of holy books, he esteemed the clergy and he was charitable to all. Despite his young age, he chose for himself the exploit of strict fasting and prayerful vigilance. Prince Gleb died in the year 1174, at age nineteen.
His incorrupt relics were preserved and glorified by miracles. In the year 1238, during the time of the incursion of Batu upon the Russian Land, the Tatars burned the cathedral at Vladimir. In this conflagration perished Bishop Metrophanes, Great-princess Agatha, wife of Great-prince George Vsevolodovich (+ 1238), and many inhabitants of the city of Vladimir, who were locked in the cathedral church. The fire, however, did not even touch the tomb of Saint Gleb. Years later, in July 1410, Tatars again descended upon Vladimir. In plundering the city, they began to sack the cathedral church treasury, having murdered the door-keeper Patrick. Supposing that treasure was hidden in the saint’s tomb, they set about to break it open. Just as the Tatars touched the stone crypt of Saint Gleb, flames shot forth from it, and the Tatars fled the city in terror.
Through the prayers of the holy prince the city was saved from an incursion of Polish-Lithuanian plunderers in 1613.
The celebration of Saint Gleb was established in the year 1702, and then also a service was written to him, and somewhat later, a Life. His relics rest in the Dormition cathedral in Vladimir. In the year 1774 the south chapel of the cathedral was dedicated to him. Prince Gleb is revered as the special patron and defender of the city of Vladimir.
