"George, this truly great and glorious Martyr of Christ, was born of a father from Cappadocia and a mother from Palestine. Being a military tribune, or chiliarch (that is, a commander of a thousand troops), he was illustrious in battle and highly honored for his courage. When he learned that the Emperor Diocletian was preparing a persecution of the Christians, Saint George presented himself publicly before the Emperor and denounced him. When threats and promises could not move him from his steadfast confession, he was put to unheard-of tortures, which he endured with great bravery, overcoming them by his faith and love towards Christ. By the wondrous signs that took place in his contest, he guided many to the knowledge of the truth, including Queen Alexandra, wife of Diocletion, and was finally beheaded in 296 in Nicomedia." (Great Horologion) The Empress Alexandra, along with a pagan priest who confessed Christ due to George's witness, were executed together with the Great Martyr. St Alexandra is commemorated on April 21/May 4.

Neither the Great Horologion nor the Prologue, nor the Church's services to St George, mention the most popular story of St George, his slaying of a dragon. Though many icons of the Saint show him mounted on horseback, slaying a dragon with a spear, the story is thought by many to be legendary, and the dragon in the icon symbolic.
