Note 89b — THE GODODIN.

Deivyr and Bryneich, (Deira and Bernicia) are situated on the eastern coast of the island, the river Humber, as we learn from the Triads, (Myv. Arch. vol. ii. p. 68) flowing through a portion thereof. In a document which has been published in the Iolo MSS. Argoed Derwennydd, (Derwent wood probably) and the river Trenn or Trent, are mentioned as the extreme boundaries of the region. The triads moreover speak of the three sons of Dysgyvedawg, (or Dysgyvyndawd) viz. Gall, Difedel, and Ysgavnell, under the appellation of the “three monarchs of Deivyr and Bryneich,” (Ibid. p. 64) about the period, as it would appear, of our Poem.
