ENTh e article presents the life of nobleman Jan Kunowski, a three times director of the Lithuanian Evangelical Reformed Provincial Synod in the Grand Duchy of Lithuania. There are various forms of his activity described - as a poet, condotierre, cartographer, diplomat, offi cial, royal secretary, and landowner. His career was not as successful as it had been indicated by both his intellectual potential and patronage of his patron Aleksander Gosiewski.
