A prototype of this ring was discovered in Augsburg (Ernst Reiter Platz, Bavaria). It is one of the oldest rings of its kind, and its engraving is executed in a unique Gothic script, commonly found on medieval talismans and amulets. The ring bears only two names.
Archaeologists have discovered prototypes of this ring in Donauwörth (Bavaria, Germany), Florence (Italy), Amiens (France), Britain, and so on. It once belonged to the powerful von Veltheim family, and its magical names were even used by abbots, who engraved them on their personal seals, known as "sigillum secretum," or "secret seals." The purpose of such a ring was to protect its owner. It was worn not only for protection against spells or demons but also to maintain health and prevent seizures.
