Clodvis, Codo
First king of Cornwall in the Prose Tristan, apparently based on Clovis, the first Christian king of the Franks.
Tristan makes him the ancestor of Tristan. He had a son named Anzilere and a daughter named Cressille. His son killed King Appollo of Lyoness, for which Clodoveus executed him.
King Clodoveus adopted King Apollo’s orphaned son, Candaces. When Candaces came of age, Clodoveus married him to his daughter and made him heir to Cornwall.
