Holden, Holdyne, Howeldin

One of Arthur’s nobles, to whom Arthur gave either Flanders (in Geoffrey of Monmouth) or Boulogne (in Wace).

Holdin assisted Arthur in the Roman war. He led a company at the Battle of Soissons, where he and King Alifatima of Spain mortally wounded each other. Arthur had him buried in his city of Thérouanne or Tervanna.

In the Prose Brut, he is Arthur’s chamberlain. Thomas Bek calls him the "King of the Ruteni".
