The 9th-century version of Englynion y Beddau (The Stanzas of the Graves) gives Bedwyr's final resting place on Tryfan. In the hagiography of Cadoc, Bedwyr is alongside Arthur and Cei in dealing with King Gwynllyw of Gwynllwg's abduction of Gwladys from her father's court in Brycheiniog. A possible allusion to Bedwyr could be found in the reference to Bedwyr's well in the 9th-century Marwnad Cadwallon ap Cadfan. The Welsh Triads name Bedwyr as Battle-Diademed, and a superior to Drystan, Hueil mab Caw and even Cei. A catchphrase often quipped by Cei, by the hand of my friend is likely a reference to Bedwyr's disability.
