Stone

Oval, 
Stone:  St Michael & St Wulfhad
Brit.Lib.:

A few years ago, a seal was discovered in Cobham, Surrey, belonging to Stone Priory, Staffs.  How it ended up in a field in Cobham, no-one knows.  The good people of Stone stumped up £8000 to buy it from a detectorist (ouch), and it's now back in Stone.  And quite right, too.  It's a lovely seal.

You can read a description of it and see more pictures here.

The legend is +S'ECCE SCE MARIE ET SCI W(V)LFADI MARTIRIS DE STANIS.  The BVM appears to be holding a distaff.

No reverse matrix survives, so far as we know; perhaps that would have had the junior saint of the priory's dedication, St Wulfade, on it!
