Later fifteenth-century poem to Cynog, surviving in a number of manuscripts.

The text describes how Cynog, having ruled as a king in Ireland, renounces his throne for an eremitical life, comes to Wales, and battles giants and monsters on behalf of the local population. He triumphs with the aid of a heaven-sent weapon, a marvellous torque. Ultimately, however, he is martyred by decapitation, though he survives for a time with his head attached by a cord.
