Note 283 — HISTORY OF THE BRITONS.
Reading edition
These words relate evidently to some cause of dispute between the Romans, Ambrosius, and Vortigern. Vortigern is said to have been sovereign of the Dimetæ, and Ambrosius son to the king of the Dumnonii. The latter was half a Roman by descent, and naturally supported the Roman interest: the former was entirely a Briton, and as naturally seconded by the original Britons. See Whitaker's Manchester, b. ii. c. 2.
