An Adar Llwch Gwin () is a legendary creature from Welsh tradition depicted as very large and intelligent birds, often considered to be related to the griffin.Rose, Carol: Giants, Monsters and Dragons. Norton 2000.
Lore The Adar Llwch Gwin were given to a warrior named Drudwas ap Tryffin by his fairy wife. The name derives from the Welsh words ("bird"), ("dust"), and ("wine"). These birds were said to understand human speech and to obey whatever command was given to them by their master. However, when Drudwas was about to do battle with the hero Arthur he commanded them to kill the first man to enter the battle. Arthur himself was delayed and the birds ultimately turned on Drudwas when he walked onto the battlefield first, tearing him to pieces. A WELSH CLASSICAL DICTIONARY page 232.. Later, in medieval Welsh poetry, the phrase came to describe all types of raptors including hawks, falcons, and brave men.
Song The story of the Adar Llwch Gwin is associated with a song. A legend states that the song was sung or composed by the birds to mourn the death of their master.
Possible Lyrics The lyrics are atributed to Llywarch Hen.
