Of unknown meaning, perhaps from Din Eidyn, the old name for EDINBURGH (which appears in the early medieval Welsh poem 'Y Gododdin'), or possibly an Anglicized form of Dunawd. Sir Dinadan is one of King Arthur's knights of the round table in Arthurian legend. He is the son of Sir Brunor Senior, the 'Good Knight without Fear,' and brother of Sirs Breunor le Noir and Daniel, and is also known as a good friend of Tristan's. As with the characters Palamedes and Lamorak, Dinadan was first named in Prose Tristan, only then to appear later in the Post-Vulgate Cycle and Sir Thomas Malory's Le Morte d'Arthur. Sir Dinadan is known as one of the wittiest and most social of King Arthur's knights.
