Sefer Nizzahon Yashan

Sefer Nizzahon Yashan (ספר ניצחון) "The (old) Book of Victory" is an anonymous 13th Century Jewish apologetic text originating in Germany. The name "old" (Hebrew yashan, Latin vetus) is attached to distinguish the work from Yom-Tov Lipmann-Muhlhausen of Prague's work of the same name, Sefer Nizzahon, written between 1401-1405. A modern edition was published by Mordechai Breuer in 1978, and a critical edition by David Berger (professor) in 2008 (1st ed.: Philadelphia, Jewish Publication Society, 1979). The work was known and responded to by Protestant Hebraists and polemicists, including Johann Reuchlin, Sebastian Münster, Wolfgang Capito, Immanuel Tremellius, Jean Calvin, and Martin Luther.
