Note 123c — THE GODODIN.
John Williams translation
“O barth deheu.” “Deheu,” literally means the right, and as the mid-day sun is to the right of a person looking eastward, the word is also taken to signify the south; hence we say “deheudir” for South Wales. The “parth deheu” in this place must accordingly mean some district south of the scene of action, such as Wales, where Gwyddno and his family resided, would be.
