[Radzyń Teutonic Castle] Seal stamp of Radzyń Chełmiński Castle.

brass; diameter of seal field 3.1 cm; height 3.5 cm; in seal field: figure in robes with a key (to the castle gate), below a wheel with eight spokes; in the rim an inscription: SIGILLUM CASTELLI MONERENSIS.
Poland, first half of the 18th century.
There is a Teutonic castle in Radzyń near Grudziądz, which fell to the Republic of Poland after the Peace of Torun in 1466. In the 18th century, the non-golden starosty of Chelm was held by two magnates, the Czapskis, and from their period comes this seal.
The inscription in the rim means "SEAL OF THE CASTLE IN ..."; monere - from Latin means "to advise", it is a Latinized form of the name of the town of Radzyn. This locality is also evidenced by a wheel with eight spokes - the coat of arms of the city of Radzyn. Other cities in Europe that have a coat of arms with a wheel do not have castles, or their names do not match that of the seal.
A unique type of seal of a castle ruler. Attention is drawn to the artistic workmanship, probably of an atelier in Gdansk.
Provenance: seal acquired in the 1980s in Gdansk, together with two seals with the Leliwa Czapski coat of arms.
