Amaethon

In Welsh mythology, Amaethon (Amaethon fab Dôn, meaning "Amaethon son of Dôn") was the god of agriculture, and the son of the goddess Dôn. His name means "labourer" or "ploughman", and he is cited as being responsible for the Cad Goddeu, or "Battle of Trees", between the lord of the otherworld, Arawn, and the Children of Dôn (the Welsh version of the Tuatha Dé Danann).

Etymology
This theonym is derived from Proto-Celtic *Ambaxtonos meaning great follower, servant or ploughman, an augmentative form of ambactos (ultimately from *ambhi-ag-to- ).
