Dumnagual Moilmut, King of Bryneich
(Welsh-Dyfnwal, Latin-Domnovellaunus, English-Donald)
The son of Garbonian, he succeeded to the Bryneich throne upon his father's death, probably in the late 5th century. Little is known of him, but he may have been the prototype for Geoffrey of Monmouth's character of the same name which he transported back in time to a mythical landscape around 450 bc. This man was said to have had to fight many battles to secure his position as King, but later became well established and was a wise and respected law-maker. With the epithet of Moel, he appears at King Arthur's Court in the tale of Culhwch and Olwen. Dumnagual was apparently succeeded by his eldest son, Bran Hen, though the kingdom may have been divided.
