 Seweryn Boner, in agreements with the Thurn und Taxis family post, tried to establish a regular postal service in Cracow, which was enabled on a small scale, however the enterprise was closed down after his death.The death of the Polish queen Bona Sforza in 1557 was the factor that influenced the emergence of the Polish Post, because King Sigismund II Augustus had to maintain permanent and regular correspondence with Italy in order to collect his inheritance.On the 18 October 1558 the monarch granted the right for the establishment and management of the post to the Italian Prospero Provana.
