A very rare tractate of the first Talmud edition of the Isaac b. Aaron of Prostitz (Prossnitz) printing press. Isaac who was trained in Italy and received a 50 years' licence from Sigismund II Augustus to set up a Hebrew press in 1569. He acquired his equipment from the Venetian printers Cavalli and Grypho and also brought with him from Italy the scholarly proofreader Samuel Boehm. In the next 60 years Isaac and his successors (sons and nephews) produced some 200 books, of which 73 were in Yiddish. The Babylonian Talmud was printed twice, this edition 1602–08 and again in 1616–20.
