really fascinating - we can rule out roman? i think the clue lies in the style of the lettering which is a bit Gothic? GOt to be medieval? says he a medieval enthusiast. if we could have better close ups of the letter etc. there must a website or university library with an archive on stonemasons cut lettering etc. its the stone equivalent of typeset! are you sure its water feature? it looks a bit grave like or at least a memorial to someone who has died? but then again i could be totally wrong. fascinating.
Looks a bit Victorian gothic to me - reminds me of the Houses of Parliament and similar work by Pugin. But I can't read it - I'd have expected it to be in either English or Latin, and it doesn't look like either.
Have you got a clearer picture of some more of the text lechef?
Hmmm - I've had another look, and I still can't read it. It doesn't look like French, either modern or archaic, both of which I can read (or thought I could! bit rusty on the older stuff as I last did it in the 1970s), or Breton, which I can sort of puzzle my way through as it's related to Welsh.
Thankyou guys for your interest in my query. Next time I am in France I will take some better pictures for your consideration, perhaps you may be able to help me out then. Many thanks. Le chef
