CORRECTION A learned reader emails to say that “it’s the original stone, not a replacement. But it looks quite different in its restored state and, especially, with the lettering picked out in black. An exhaustive account of the restoration can be found here“.
I’ve also discovered that I didn’t know the difference between a gravestone and a ledger stone :-( It’s such a salutary thing to have smart readers.
