From "Pa beth yw Dyn" by Waldo Williams

Beth yw canu? Cael o'r creu
Ei hen athrylith.
Beth yw gweithio ond gwneud cân
O'r coed a'r gwenith?

... and Tony Conran's translation, "What is Man"

Singing, what is it? The ancient
Genius of the creation.
What's work but making a song
Of the trees and the wheat?
