GLASCURION refers possibly to the Bard Geraint, who presided over an "Eisteddfodd" or music competition and festival in the ninth century. There are several bards named Geraint in Welsh musical history. One Geraint is the subject of a ballad in Percy's Reliques III: 43.1765; he harped in the queen's chamber "till the ladies waxed wood." Thomas Parry points out that many references to the Bard Geraint in the Myvyrian Archaiology of Wales are inventions of Edward Williams (1747-1826), written under the pen name Iolo.

The Dreamer sees the Bret Glascurion in Fame's house among the harpers, who include Chiron and Orion, HF III.1201-1208. [Chiron: Orion]

Glascurion is a compound of Glas Geraint, Geraint the Blue Bard, and appears in final rhyming position, HF III.1208.
