The myth of St George and the Dragon is embedded in the history of not only England but also many other parts of the world. In the most recorded version of the story, an evil dragon demands a sheep from a kingdom every day to feed. Once all the sheep have been killed, the dragon demands the sacrifice of a child every day, drawn by lot from all the households of the kingdom. One day, the princess is chosen to be the victim. By chance, St George arrives and bravely subdues the dragon before killing it and saving the kingdom from this evil. In many versions of the story, he also falls in love with, and marries, the princess.
