These poems are derived from those published in the Bulletin of the Board of Celtic Studies iii, 1927–1929, pp 4–21;. The first Englyn (number 28) is to Heledd and the second (number 34) is to Llywarch Hen. The verses themselves are a part of the Englynion y Clyweit originating during the late twelfth century as an aide memoire in the recalling of proverbs.
