Can you name a great work of art inspired by the Old Testament? Oh, that's easy: Michelangelo's David, Verdi's Nabucco, Cecil B. DeMille's The Ten Commandments. Do you know of any famous work inspired by the New Testament? Piece of cake: Leonardo's Last Supper, Bach's St. Matthew Passion, Monty Python's Life of Brian. Now for the real test: can you list a few masterpieces inspired by the Talmud?Though Jewish communities that studied the Talmud spread over large parts of the world, they did not play an important role in the building of the Chinese empires, in the European voyages of discovery, in the establishment of the democratic system, or in the Industrial Revolution.
