Marvelous

1. Marvelous Ball

   A hill in Britain.

   It had a brass ball on top that appeared - depending on the distance from which it was viewed - as a horse, a mule, a hound, a fox, or just a ball.

   Lancelot used the Marvelous Ball as the launching point for his expedition to recapture his homeland Genewis.

   
   

2. Marvelous Stone

   The enchanted stone on which Yvain poured water, summoning the lord of the fountain and beginning the events related in the various versions of Owain or Yvain.

   Wolfram von Eschenbach gives this name to the stone but does not tell the story.
