Experts at the British Library have matched a bronze seal matrix, dating to the 13th century, with a 19th century sulphur cast of a seal belonging to the Augustinian canons of Stone Priory in Staffordshire. The matrix was discovered recently in a Surrey field. (photos)

Experts are still puzzled over how the seal matrix from Staffordshire ended up in Surrey, theorizing that the matrix was lost during the dissolution of the monasteries during the reign of Henry VIII.
