De furtu. Il più antico incantesimo di area tedesca per riconoscere il ladro: eredità e contesto culturale

De furto (Clm. 536 Bayerische Staatsbibliothek München, f. 89v) is written in the same 12th c. manuscript containing the famous Prüller Herbal and Prüller Lapidary, as well as a MHG worm charm. The MHG theft charm can be probably dated 13th c. The text includes directions for performance and the use of a Zaubersieb in order to find out the thief. This mantic tool was later on well attested in German Medieval Folklore and Literature, and this text might be the very first written evidence.
