Cwn Annwn — Hell Hounds
Cwn Annwn were supposed to have been supernatural hounds whose yelling or howling on dark nights foreboded a death. If the howling was faint, it meant that the pack was close at hand, if loud, the hounds were only hunting at a distance. These hounds were supposed to watch for the souls of notoriously wicked men about to die.
An old farmer, named Mr. Thomas Stephens, Llwyncelyn, Llanarth, Cardiganshire, informed me that his brother once heard the bark of these hounds on the road near Bronwen.
