For Saint George himself, festivities can range from the civic to national to professional observances for the many places and vocations (including blacksmiths, butchers, farmers, miners and beer-barrel makers) he covers. The historical personage was an accomplished and respected leader of the imperial guard in Roman Palestine, and although a favourite of the Emperor, was martyred for making a spectacle of his refusal to recognize the pagan household gods. Apparently, his faith inspired a revolt among the people and military ranks, overturning the ban against Christianity. Where the bit about the dragon comes in is not so clear. I always felt kind of sorry for the dragon, but it was more than just a nuisance, demanding livestock- or maiden-sacrifices from villagers in exchange for access to their oasis and water supply. Then, instead of taking the act, George slaying the dragon (symbolizing Rome, perhaps) to save the life of the chieftain’s daughter who drew the bad lot after all the sheep and goats had been devoured, as a fait accompli, I prefer to think of it as a continuous battle, a tumbling and constant struggle like the eternal standoffs seen in the constellations.
This fiery perseverance is something internalized, perhaps, as the choices that confront us all the time and the sometimes delayed realization that choices and acts have consequences. I like how this imagery has been propagated and the hero is acknowledged in his homelands and far beyond, and his icons and devotions are spread from the Middle East to the nation of Georgia, to the flag of England and the Arab world because of widespread miraculous acts and visions of the Saint on the eve of battle.
