 Together with Abraomas Kulvietis, Rapolionis was one of the very first authors to write in the Lithuanian language.While Rapolionis and Kulvietis died early leaving their work unfinished, they laid the foundations for future Lithuanian writers and translators.Very little is known about Rapolionis' life prior to his studies at the University of Wittenberg in 1542 and most of his early biography is a conjecture.
