trying to find a conscript

Hi, I'm looking for information on a conscript, but all I can remember
is that it looks like intertwined celtic knots, that it is ornamental
and that it is made to be carved into stone.
I don't remember how or where I found it, who made it or what language
it was for.

If this rings a bell for anyone, or for everyone, please post a link.

thanks,
