Background
Budic II was born in Cornouaille to a member of its royal family, either Erich or Cybydan.
Budic II was born in Cornouaille to a member of its royal family, either Erich or Cybydan.
He was the father of Hoel Mawr and is probably to be identified with the Emyr Llydaw ("Emperor of Brittany") and King Nentres who appear in Arthurian legend. Upon his death, his kingdom was usurped by Macliau, king of the neighboring Veneti. After the death of his usurping relative, he returned to Cornouaille to claim the Breton throne, later joined by Saint Teilo whom he reputedly persuaded to rid the area of a terrible dragon that had been terrorising the countryside.
Teilo was able to subdue the beast and tied it to a rock in the sea.
Some sources claim he died in 545. However, this contradicts other sources which claim that Saint Teilo had fled to France in 549 to escape the Yellow Plague of Rhos and had spent time in Brittany in Budic"s company.
In Geoffrey of Monmouth"s pseudohistorical History of the Kings of Britain, Budic is said at different places to have married a sister of Aurelius Ambrosius and Uther Pendragon (making him Arthur"s uncle) and to have married Pendragon"s daughter Anna (making him Arthur"s brother-in-law). A fourth son (credited to "Emyr Llydaw" in late Welsh sources) was Hoel I Mawr, whose son Tewdwr eventually succeeded to the kingdom of Cornouaille.
Another was Saint Gwen the Three-Breasted, who married Saint Fragan (also a member of the dynasty in Dumnonia) and bore him Saints Wethoc, Jacut, Winwaloe, and Chreirbia.
