Amaethon

In Insular Brythonic mythology, Amaethon was a god of agriculture, a son of Don and Beli.

He stole a dog, lapwing and roebuck[?] from Arawn, leading to the Battle of Cath Godeau[?] between the underworld gods and monsters and the children of Don. In this battle, Amaethon's brother, Gwydion, turned trees into warriors that helped the children of Don win.
