Richard
In the Prophécies de Merlin, the son of the King of Jerusalem.
The King of Baghdad invaded his lands. He was sent by the Pope on a diplomatic mission to Arthur’s court to obtain aid for Jerusalem which was menaced by the King of Baudec. A force under Henry the Courtly arrived with British troops to drive the pagans away.
When Richard became King of Jerusalem himself, he attacked Sarras but, as no Crusader was able to defeat the gigantic ruler, Alchendic, a truce ensued.
