Saint George (c. 275/281 – 303) was a Roman soldier from Syria Palaestina and a soldier in the Guard of Diocletian.
According to the wikipedia:
"It is likely that Saint George was born to a Christian noble family in Lod, Syria Palaestina during the late third century between about 275 AD and 285 AD, and he died in Nicomedia. His father, Gerontius, was a Roman army official from Cappadocia and his mother, Polychronia, was from Palestine. They were both Christians and from noble families of Anici, so the child was raised with Christian beliefs. They decided to call him Georgius (Latin) or Geōrgios (Greek), meaning "worker of the land". At the age of 14, George lost his father; a few years later, George's mother, Polychronia, died. Eastern accounts give the names of his parents as Anastasius and Theobaste.
Then George decided to go to Nicomedia, the imperial city of that time, and present himself to Emperor Diocletian to apply for a career as a soldier. Diocletian welcomed him with open arms, as he had known his father, Gerontius — one of his finest soldiers. By his late 20s, George was promoted to the rank of Tribunus and stationed as an imperial guard of the Emperor at Nicomedia.
In the year AD 302, Diocletian (influenced by Galerius) issued an edict that every Christian soldier in the army should be arrested and every other soldier should offer a sacrifice to the Roman gods of the time. However George objected and with the courage of his faith approached the Emperor and ruler. Diocletian was upset, not wanting to lose his best tribune and the son of his best official, Gerontius. George loudly renounced the Emperor's edict, and in front of his fellow soldiers and Tribunes he claimed himself to be a Christian and declared his worship of Jesus Christ. Diocletian attempted to convert George, even offering gifts of land, money and slaves if he made a sacrifice to the Roman gods. The Emperor made many offers, but George never accepted.
Recognizing the futility of his efforts, Diocletian was left with no choice but to have him executed for his refusal. Before the execution George gave his wealth to the poor and prepared himself. After various torture sessions, including laceration on a wheel of swords in which he was resuscitated three times, George was executed by decapitation before Nicomedia's city wall, on April 23, 303. A witness of his suffering convinced Empress Alexandra and Athanasius, a pagan priest, to become Christians as well, and so they joined George in martyrdom. His body was returned to Lydda in Palestine for burial, where Christians soon came to honour him as a martyr.
St George and the dragon
The wiki reports:
"According to the Golden Legend, the narrative episode of Saint George and the Dragon took place in a place he called "Silene", in Libya; the Golden Legend is the first to place this legend in Libya as a sufficiently exotic locale, where a dragon might be imagined. In the tenth-century Georgian narrative, the place is the fictional city of Lasia, and it is the godless Emperor who is Selinus.
The town had a pond, as large as a lake, where a plague-bearing dragon dwelled that envenomed all the countryside. To appease the dragon, the people of Silene used to feed it two sheep every day, and when the sheep failed, they fed it their children, chosen by lottery. It happened that the lot fell on the king's daughter, who is in some versions of the story called Sabra. The king, distraught with grief, told the people they could have all his gold and silver and half of his kingdom if his daughter were spared; the people refused. The daughter was sent out to the lake, decked out as a bride, to be fed to the dragon.
Saint George by chance rode past the lake. The princess, trembling, sought to send him away, but George vowed to remain. The dragon reared out of the lake while they were conversing. Saint George fortified himself with the Sign of the Cross, charged it on horseback with his lance, and gave it a grievous wound. He then called to the princess to throw him her girdle, and he put it around the dragon's neck. When she did so, the dragon followed the girl like a meek beast on a leash.
The princess and Saint George led the dragon back to the city of Silene, where it terrified the people at its approach. But Saint George called out to them, saying that if they consented to become Christians and be baptised, he would slay the dragon before them. The king and the people of Silene converted to Christianity, George slew the dragon, and the body was carted out of the city on four ox-carts. "Fifteen thousand men baptized, without women and children." On the site where the dragon died, the king built a church to the Blessed Virgin Mary and Saint George, and from its altar a spring arose whose waters cured all disease.
Traditionally, the sword with which St. George slew the dragon was called Ascalon, a name recalling the city of Ashkelon, Israel. From this tradition, the name Ascalon was used by Winston Churchill for his personal aircraft during World War II (records at Bletchley Park), since St. George is the Patron Saint of England."
