Overview
Erbin of Dumnonia (Latin: Urbanus; c. 427 – c. 480) was a 5th-century King of Dumnonia (now Cornwall and Devon) and saint of Wales.
Monarch
Traditionally, Erbin was a King of Dumnonia, the son of Constantine Corneu and the father of Geraint. He was the brother of Saint Digain, founder of the church at Llangernyw. Erbin succeeded his father as King of Dumnonia around 443.
Erbin chiefly appears in Geraint and Enid, one of the Three Welsh Romances of the Mabinogion. In the romance of Culhwch and Olwen he is the father of Gereint, Dywel, and Ermid, the latter two knights at Arthur's court at Celliwig. According to the Bonedd y Saint, Saint Cybi is Erbin's great-grandson through Cybi's father Salomon of Cornwall.
In the Mabinogion he appears as an old king whose realm is subject to attacks from his enemies. He recalls his son from the court of King Artu to aid him in the war and restores the Dumnonian power, then abdicates in his son's favour. About 480 Erbin dies.
