one of the fathers of Eastern Slavonic printing (along with Schweipolt Fiol and Francysk Skaryna), he was the first known Russian printer in Muscovy and the Polish-Lithuanian Commonwealth, he was also a skilled cannon maker and the inventor of a multibarreled mortar. Neither his place nor his date of birth are known. It is assumed that he was born circa 1510, most likely, in Moscow: he called himself a Muscovite even after his move to Lithuania, and in his afterword to the Lviv Apostle he named Moscow "our home, our fatherland and our kin".
