Here, but not all there.... thats me.

I remember something about a branch of the Keppoch clan who lived on one of the islands, I think. They offended the spring and it moved onto the other side of the island, and eventually disappeared altogether. They were moved to new lands near Callandar. Then the whole clan took a short cut across a frozen loch near Callander one day, all together cos they were following the coffin in a funeral procession, and the ice broke and they all fell in and drowned. Lochan na Corps they called it after that. They didn't get on well with the waters that lot, whole branch of that clan dead in one go.

Colin and Janet Bord wrote Sacred Wells, Sacred Waters, which lists an awful lot of wells in it, and the customs and traditions they are famous for.

Piscina symbol as per the chalice well is an obvious evolution of a pagan symbol into a christian one, tjj. I'd like to donate a nicer cast iron well door cover to our local well, but I dunno if they would use it if I did. The one it has is a bit utilitarian looking.

I worked on a very old house once that was only one step up from a wattle and daube affair that had a well in the scullery that had raised sides and a 'lid' on it about 3ft in diameter. It had been in daily use right up until we began work on it when the previous owner snuffed it. As I recall the water level was really quite high only being I would estimate about 10ft down and pretty foul stuff which is probably how the last owner died!!
And my present neighbouring farmer in Cornwall has a brook that actually runs through part of his farmhouse. It's really odd to go in and stand there talking to him in this room with a stream running past you!!
