Feast of St. George, April 23

St. George and the Dragon, by Paolo Uccello, 1456

St. George existed, all right (he died around 303 A.D.), but that 's pretty much all we know about him. We always seem to see hims laying a dragon with a damsel in distress in the background. Catholic On-Line suggests the dragon represents various vices; or maybe  it's the Roman Empire (St. George was martyred by the Emperor Diocletian). Or how about the devil (Revelations 12:2-9) :

^* A great sign appeared in the sky, a woman^* clothed with the sun, with the moon under her feet, and on her head a crown of twelve stars.^a 2She was with child and wailed aloud in pain as she labored to give birth.^* 3Then another sign appeared in the sky; it was a huge red dragon,^* with seven heads and ten horns, and on its heads were seven diadems.^b 4Its tail swept away a third of the stars in the sky and hurled them down to the earth. Then the dragon stood before the woman about to give birth, to devour her child when she gave birth.^c 5She gave birth to a son, a male child, destined to rule all the nations with an iron rod.^* Her child was caught up to God and his throne.^d 6The woman herself fled into the desert where she had a place prepared by God, that there she might be taken care of for twelve hundred and sixty days.^* 7^* Then war broke out in heaven; Michael^* and his angels battled against the dragon. The dragon and its angels fought back, 8but they did not prevail and there was no longer any place for them in heaven. 9The huge dragon, the ancient serpent,^* who is called the Devil and Satan, who deceived the whole world, was thrown down to earth, and its angels were thrown down with it.^e
