The story of
The Dream of Rhonabwy in the 12th century
Red Book of Hergest is a prose literary tale where the main character travels to the time of
King Arthur in a dream. There he sees famous men from many historical eras. In a passage where 24 knights arrive to seek a truce with the famous Arthur, Arthur considers the request by assembling his counselors where "a tall, auburn, curly-headed man" was standing. Rhonabwy asks who he is, and is told that he is
Rhun ap Maelgwn Gwynedd, a man who may join in counsel with anyone, because there was none in Britain better skilled in counsel than he. Marwnad Rhun (English: Elegy of Rhun), once believed to be the work of
Taliesin but no longer accepted as such, laments Rhun's death in battle during that war with the North.
Rhun, son of Maelgwn, appears in two of the medieval
Welsh Triads, as one of the 'Fair Princes of the Isle of Britain', and as one of the 'Golden-banded Ones of the Isle of Britain'.
Rhûn also appears as a realm in the East of the map in
J. R. R. Tolkien's
The Hobbit and
The Lord of the Rings ==List of bearers==
