Michaelmas Day was formerly regarded with suspicion in Wales. It was credited with uncanny power. There was an old superstition that on this night the Cistfaens, or warriors' graves, in all parts of the Principality were illuminated by spectral lights, and it was very unlucky to walk near those places on Michaelmas Eve or Night; for on those two occasions the ghosts of ancient warmen were engaged in deadly fray around their lonely resting-places.

One of the seven wonders of Glamorgan is the tumulus near the Bodvoc Stone on Margam Mountain. It is called the "Twmpath Diwlith" - the dewless mound. Tradition tells us that no dew ever falls on this mound.

Folklore of the District. (By Martin Phillips.)

Camden, in his "Britannia" (1610) remarks: 'In the very top of an hill called Mynyd Margan, there is erected of exceeding hard grit, a monument or gravestone, four foot long, and one foot broad with an inscription, which whosoever shall happen to read, the ignorant common people dwelling there about, give it out upon a credulous error, that he shall be sure to die within a little while after. Let the reader therefore look to himself, if any dare read it, for, let him assure himself that he shall for certain die after it.'

Writing in 1722, Daniel Defoe ('Tour through England and Wales') makes the following comment: 'In this neighbourhood, near Mynydd Margam, we saw the famous monument mentioned by Mr Camden, on a hill, with the inscription which the people are so terrified at, that nobody will care to read it; for they have a tradition from father to son, that whoever ventures to read it, will die within a month. We did not scruple the adventure at all, but when we came to try, the letters were so defaced by time, that we were effectually secured from the danger, the inscription not being anything near so legible as it seems it was in Camden's time.'

The inscription is still perfectly legible, and presumably the mountain climb did not appeal to Defoe who frequently expressed his abhorrence of Welsh antiquities and Welsh mountains, and apparently, he had no desire to risk the deciphering of the 'terrifying' inscription. Incidentally he has been described by a recent writer as 'one of the world's greatest liars, with a peculiar art for making fictitious narrative sound like the truth'. Defoe's description of other Welsh antiquities confirms the statement.

The Bodvoc stone was believed to cover buried treasure, and about sixty years ago a wide hole about five feet deep was dug around it at night. The stone was overthrown, and for a long period was covered with water. It was subsequently set up in an upright position, and the erection of an iron railing protected it from further harm. Guarding the alleged treasure was the inevitable ghost, which was said to be that of the departed Bodvoc.

Near the stone is the huge mound known as 'Y Twmpath Diwllith' (the Dewless Mound), which was erroneously considered to be always immune from dew. The word 'Diwllith' became translated to 'Dewless', but apparently it is a corruption of "Duw-lith" (God's Lesson). The mound is situated on the boundary line between Llangynvyd and Margam parishes, and in former times, during the yearly perambulation of the boundary, the customary lesson was read by the priest when the mound was reached.
