This was possibly a gift from King Matthias I Corvinus of Hungary to Johannes von Kranichberg, the owner of Petronell. Engraved with a diamond, the inscription refers to the visit of Emperor Matthias and Empress Anna to Petronell Palace on 12 April 1613, an occasion on which the Emperor confirmed the privileges of the lord of the castle, Hans Christoph von Unverzagt.
