THE HAUNTING OF LLANIDLOES
There was once a lady who died but could not rest in her grave because of her misdeeds, and she haunted the locals until they could stand it no more. Somehow they enticed her to shrink and enter into a bottle, after appearing in a good many hideous forms; but when she got into the bottle, they corked it down securely, and the bottle was cast into the pool underneath the Short bridge at Llanidloes, There the lady was to remain until the ivy that grow up the buttresses should overgrow the sides of the bridge, and reach the parapet. In the year 1848, the old bridge was blown up, and a new one built instead of it. So for all anyone knows, she is still trapped in her bottle!
The farmer then sent for Griffiths, an Independent minister at Llanarmon, who enticed the ghost to the barn. The ghost then changed its appearance to the form of a lion, but could not touch Griffiths, because he stood in the centre of a circle, over which the lion could not pass. Griffiths tricked the ghost into appearing in a less formidable shape, and it changed into a mastiff, but Griffiths demanded that it change to something smaller. At last, the ghost appeared as a fly, which was captured by Griffiths and secured in his tobacco box, This box he buried under a large stone in the river, just below the bridge, near the Llandegla Mills, and there the spirit is forced to remain until a certain tree, which grows by the bridge, reaches the height of the parapet. When this takes place, the spirit will have power to regain his liberty. To prevent this tree from growing, the school children, even to this day, nip the upper branches to limit its upward growth.
The next day, the exciseman got up early and went away, but, before long, he returned to Ty Felin accompanied by a policeman, whom he requested to dig in the place where his mark was. This was done and underneath a superficial covering, a deep well was discovered, and in it a corpse.
Under interrogation, the occupier of the house confessed that a travelling Jew, selling jewelry and such items, once lodged with him, and that he had murdered him and cast his body in the well.
The Cŵn Annwn also came to be regarded as the escorts of souls on their journey to the Otherworld.
The hounds are sometimes accompanied by a fearsome hag called Mallt-y-Nos, "Matilda of the Night". An alternative name in Welsh folklore is Cŵn Mamau ("Hounds of the Mothers").
Hunting grounds for the Cŵn Annwn are said to include the mountain of Cadair Idris, where it is believed "the howling of these huge dogs foretold death to anyone who heard them.The locals claim that the mountain is haunted, and that anyone who spends the night on top of Cadair Idris will wake up either a madman or a poet. Different legends surround the mountain and one of the earliest claims that the giant Idris lived there. Three large stones rest at the foot of the mountain, and legend says that Idris got angry once and kicked them, sending them rolling down the mountainside.
Other Welsh legends state, however, that Arthur made his kingdom there, hence the name Cadair Idris: or the Seat of Idris.
In 1852, on a cold winter's morning, John Roberts a farm labourer was setting out to work when he found a youth blocking his path. With a harmless gesture he made to pass the youth but all of a sudden a force propelled him through the air. He landed face down above Pwll-y-Wrach, and the force held him there despite John's best efforts to free himself. He struggled until at the sound of a cock crow he was released. The ellyll, still disguised as a youth, stood astride him and warned. " When the cuckoo sings its first note on Flint Mountain I shall come again to fetch you". John got to his feet and stumbled back home, shaken but otherwise unhurt.
The following May, John Roberts died. He had been repairing a wall at Pen-y-glyn on Flint Mountain when it collapsed and crushed him. A lady who witnessed the accident said a cuckoo had come to land on a nearby tree just as it happened. And as the body of John Roberts was being returned to his home the cuckoo followed, singing from tree to tree all the way to the front door.
