Dy alwad glywir hanner dydd
Fel ffiwt hyfrydlais uwch y rhos
Fel shwiban bugail a fo gudd
Dy alwad glywir hanner nos;
Nes clywir, pan ddwys a dy swn
Cyfarth dy anweledig gwn 
Dy braidd yw`r moel gymylau maith,
A`th basrod gwn yw`r pedwar gwynt
Gorlanna`th ddiadelloedd llaith
I`w gwasgar eilwaith ar eu hynt
Yn yrr ddiorffwys, laes ddifref
Hyd lynfnion hafodllasau`r nef.


Translation

--------------------------------------------------------------------------------
Your call is heard at high noon-day
A wistful flute across the mere;
As herdsman`s whistle far away
You call is heard at midnight clear.
Then hear we, as you swell your keen,
Barking afar, your hounds unseen. 
Your flocks the massice clouds of grey,
And all four winds, your eager hounds,
Awhile do pen then ere they stray
And scatter once more out of bounds,
A mute and restless drove on high
Amid the shielings of the sky.
