In the next few years, Mohyla established a whole network of schools around Ukraine as well as the Slavonic-Greek-Latin Academy in Vinnytsia and collegium in Kremenets. Also, he supplied the prince of Wallachia, Matei Basarab, upon his request, with a printing press and printers. In 1635 the prayer books which were published in Prince Basarab’s monastic residence were widely distributed in Wallachia (later to become Romania) and Ukraine.
