The legend of Owen and King Arthur

This legend tells the story of Owen, a poor man from Wales, and King Arthur. One day Owen was in the fields with his sheep. Suddenly:

'Hello, Owen. That's a nice stick!' A little old man with the face of a boy stood in front of him.

'You know my name! Who are you?' asked Owen.

'I'm Loomis,' said the little man. 'And under the place where you found that stick, there's gold! Take me there and the gold is yours.'
