Wales - a beautiful country area of England.  Steeped deep in the lore of fairies, King Arthur, and enchantment.  And full of ghostly legend.  In 1904-and early 1905 it was visited by strange lights that made appearances through the area of Egryn.  The first witness was a Christian woman, Mary Jones, who had a vision of Jesus in early December.  Soon afterwards in the area, the "Ghost Lights" started to appear.

On January 2, 1905, 10:40 P.M.: "Hovering above a certain farmhouse ... it appeared to me as three lamps about three yards apart ... very brilliant and dazzling, moving and jumping like a sea-wave under the influence of the sun on a very hot day. The light continued so for ten minutes. All my family saw it the same time......I saw two very bright lights, about half a mile away, one a big white light, the other smaller and red in color. The latter flashed backwards and forwards, and finally seemed in the same place again, but a few minutes after, we saw another light which seemed to be a few yards above the ground. It now looked like one big flame, and all around it seemed like one big glare of light. It flamed up and went out alternately for about ten minutes."  http://www.skygaze.com/content/strange/GhostLights.shtml

The Ghostlights continued to appear in the area, and seemed to confirm the evangalists idea of a visitation of the holy spirit of God.

Ghost lights have appeared in other places as well;  This site currently photographs and documents the current appearance of this phenomenon. http://www.ghostlights.co.uk/.

Another name for them is a will'o the wisp.  http://www.ghosts.org/ghostlights/ghostlights.html.  Willo the Wisps were know to haunt marshes and were seen boppin' along paths in front of travelers.  Some thought they were ghosts of lost travelers that would lead you to your destination.

Science has tried to explain these elusive lights but thus far has been unable to become to a rational explanation.  It's nice to have a little bit of magic and mystery left, and these bit's of floating light enchant and mystify those lucky enough to see them.
