Marhaus

"Sir Marhaus looked upon the great sword, begotten in the dragon's breath and found it passing good."

- Geoffrey of Monmouth

Sir Marhaus was a knight who was recorded in The Chronicles of Beltane. It was said that he witnessed a dragon breathing on a sword (Excalibur).

In the legend
Sir Marhaus is better known under the name of Morholt (sometime "The Morholt"). In Thomas Malory's Le Morte d'Arthur he is a Knight of the Round Table before he is slain by Sir Tristan.
