The battle of Arfderydd is mentioned numerous times in a number of medieval Welsh texts, including the
Welsh Triads (
Trioedd Ynys Prydein) and the
Red Book of Hergest (
Llyfr Coch Hergest). The Welsh Triads name Gwenddoleu's warband as one of the "Three Faithful Warbands of the Island of Britain", going on to say that they "continued to battle for a fortnight and a month after their lord was slain." The retinue of Dreon the Brave "at the Dyke of Arfderydd" is named as one of the "Three Noble Retinues", while a listing of the three "Horse-Burdens" of Britain relates that Gwrgi,
Peredur,
Dunawd the Stout and Cynfelyn Drwsgl were carried by a horse called Corvan, which enabled them to watch the clouds of dust ("battle-fog") coming from Gwenddolau and his (mounted) forces in the battle of Arfderydd.
The Dialogue of Myrddin and Taliesin, the first song of the
Black Book of Carmarthen (
Llyfr Du Caerfyrddin), refers frequently to the battle, and many warriors said to have fought in the conflict are named: Cedfyl, Cadfan, Maelgwn, Erith, Gwrith, Bran, Melgan, Rhys, Cynelyn, Cyndur, the sons of
Eliffer Eliffer Gosgorddfawr, and
Dywel fab Erbin. A further poem
Apple Trees states that Myrddin wore a golden
torque at the battle before fleeing into the
Caledonian Forest, while the poem
The Dialogue of Gwyn ap Nudd and Gwyddno Garanhir states that Gwyn ap Nudd, a mythological
psychopomp, was "at the place where was killed Gwendoleu, the son of Ceidaw, the pillar of songs, where the ravens screamed over blood." == References ==
