Note 55 — HISTORY OF CARNARVONSHIRE.

Near this Ferry, on the Anglesey shore, is a Rock known by the name of Carreg Iago, or rather Carreg yr Iacon, or Arch-Iacon; (the Archdeacon’s stone) rendered memorable on account of Archbishop Baldwin having stood up to preach the crusade upon it, at the time of his peregrinations for that purpose through Wales, 1188; and Alexander, Archdeacon of Bangor, is said to have interpreted to the people.
