 The 15th and 16th centuries were known as Poland's "Złoty Wiek" or Golden Age.Many works of Polish Renaissance art and architecture were created, including ancient synagogues in Kraków's Jewish quarter located in the north-eastern part of Kazimierz, such as the Old Synagogue.During the reign of Casimir IV, various artists came to work and live in Kraków, and Johann Haller established a printing press in the city after Kasper Straube had printed the Calendarium Cracoviense, the first work printed in Poland, in 1473.
