beg. Es ryfedaf kann wyf bard

Middle Welsh poem in englyn form, possibly of the 12th century, cast as a dialogue between Arthur and an eagle, who later reveals himself to be the spirit of Arthur’s late nephew, Eliwlad son of Madoc ap Uthyr. The conversation serves as a vehicle for religious instruction, touching on themes such as God’s omnipotence and the significance of prayer.

Ymddiddan Melwas a Gwenhwyfar
verse

Medieval Welsh dialogue poem set during a royal feast at which Gwenhwyfar taunts and converses with a stranger, who identifies himself as Melwas of an Otherworldly island (Isle of Glass). The narrative background to the poem is thought to be a tale of Arthur’s expedition to the Otherworld, in which he rescues Gwenhwyfar from an enchanted prison presided over by Melwas. Extant copies of the poem are late, dating from the 16th and 17th centuries, and show a degree of textual corruption, but scholars have argued for an older core, possibly going back to the mid-12th century.
