A Treacherous Talisman.
Reading edition
Gübner mentions that a Jew once presented himself before Duke Albrecht, of Saxony, and offered him a charm, engraved with rare signs and characters, which should render him invulnerable. The duke, determined to try it, had the Jew led out in the field, with his charm round his neck; he then drew his sword, and at the first thrust ran the Jew through.
