Amhar (also called Amr, Amir, or Anir) is a son of King Arthur mentioned in an appendix to the Historia Britonum, killed by his own father in an unrecorded conflict and buried in Ercing. His grave is one of the "Marvels of Britain":
- There is another wonder in the region which is called Ercing. A tomb is located there next to a spring which is called Licat Amr; and the name of the man who is buried in the tomb was called thus: Amr. He was the son of Arthur the soldier, and Arthur himself killed and buried him in that very place. And men come to measure the grave and find it sometimes six feet in length, sometimes nine, sometimes twelve, sometimes fifteen. At whatever length you might measure it at one time, a second time you will not find it to have the same length--and I myself have put this to the test.
A page called Amhar, son of Arthur, likely identical with the Amr of the Historia Britonum guards the king's bedchamber in the Welsh Gereint and Enid . That his significance is insufficient for Amhar to appear more than once (or even first in the list of Arthur's pages) points to illegitimacy.
