EXCALIBUR
A long time ago, so the story goes, a young boy called Arthur became the King of England after he
pulled a sword out of a stone.
The sword was Excalibur. It had a lot of power. The Lady of the Lake gave it to King Uther but
asked him to give her his firstborn child. Uther became powerful. When his first child was born, Merlin,
the magician came to take the baby. Uther tried to stop him, but thieves attacked him. Before he died, he
put Excalibur into a stone and asked Merlin to make his son a king. Merlin promised that only someone
with a pure heart could pull it out and become the next King of England.
When Arthur pulled the sword out, people were surprised. Merlin explained that Arthur as Uther’s
son and the people were happy.
Arthur was a good king. He built a big castle, Camelot, and ruled over England with his knights. He
called-them the Knights of the Round Table. Together they made England a strong country.
