A city in Logres in the Vulgate Merlin.

The Archbishop of Brice presided at Uther’s funeral and supported the young Arthur’s claim to the throne by excommunicating the rebellious leaders who opposed Arthur, and by validating the sword-in-the-stone-test.

The author of Merlin probably misinterpreted Archbishop de Brice from Wace’s Archbishop Dubric.
