Prozess gegen die Juden von Trient
The Prozess gegen die Juden von Trient, or Trial against the Jews of Trent, was an unpublished manuscript describing the trial and execution of 18 Jews from Trent, Italy, for the claimed murder of Simon of Trent in 1475. Commissioned in the 1470s, it came into the possession of a convent in Vienna in the 17th century and remained there until 1937, when it was purchased at auction by Lessing J. Rosenwald in order to avoid the document falling into the hands of the Nazis and being used to justify anti-semitism.
