George, a military leader under Dacian, "king of the Persians," inaugurates his seven years of torture by boldly coming forward to confess his belief in Christ, as Dacian is preparing to persecute Christians in the area. At Dacian's order, George is stretched out on the rack and ripped to shreds with flesh hooks, harnessed to machines that draw him apart, and then beaten, after which salt is poured into his wounds, which are rubbed with a haircloth. He is then pressed into a box pierced with nails, impaled on sharp stakes, plunged into boiling water, and has his head crushed by a hammer. All to no avail.
God comforts George in prison and informs him that he will die three deaths before entering Paradise. Dacian, confounded, summons the magician Athanasius who shows his mettle by splitting an ox in half and having each half return to life whole. Undaunted, George gulps down two portions of the magician's poison, at which point the magician confesses Christ and is summarily executed by the Persian ruler and George is returned to prison. The next day he is lacerated on a wheel of swords, cut into ten pieces, and thrown into a well that is sealed with a stone. God appears with the archangel Michael to resurrect the saint, at which point the officer in charge, Anatholius, is converted with nearly 1,100 soldiers and one woman, all of whom are immediately executed.
Dacian then redoubles his efforts: George is tied to an iron bed, molten lead is poured into his mouth and eyes after which sixty nails are driven into his skull, he is hung upside down over a fire with a stone tied around his neck, and he is shut into the revolving belly of a metal ox which is filled with swords and nails. Yet again at the end of the day the saint goes back to prison. To die his second death, George is sawed in two, boiled to bits, and just before he is buried, God, good to his word, resuscitates him after five days.
In addition to his own resilience, George's miracles include changing thrones into trees, reviving oxen, healing a sick boy, and resurrecting and baptizing men, women, and children who have been dead for centuries.
Despite fastening a glowing iron helmet to the prisoner's head, tearing and burning his body some more, and executing George a third time, Dacian fails to move the saint to sacrifice to Apollo and tries verbal persuasion instead. When George appears to consent, the delighted king invites him to the palace for the night during which the saint surreptitiously converts Dacian's wife Alexandra, who is later executed as a result. George in the meantime goes to the temple of Apollo, whose statue promptly leaves the temple and confesses his fraudulence. The saint stamps his foot, and the ground swallows up the false god. Exasperated, Dacian pronounces George's death sentence yet again. Before his [3rd] execution, though, George prays and intercedes for those who remember his name and feast day. Having survived seven years of torture and three deaths, he is finally decapitated and gratefully ascends to Heaven.
Seems legit.
