Hans Krell is credited by Dieter Koepplin as the author of a painting long associated with Lucas Cranach the Elder or his workshop - "Battle of Orsha", painted around 1524-1530. The painting, today displayed in the National Museum in Warsaw, depicts the battle which was fought on 8 September 1514 between the allied forces of the Grand Duchy of Lithuania and Kingdom of Poland and the army of Grand Duchy of Moscow. According to the specialists, the author must have taken part in the battle himself due to high knowledge of the subject. Krell's connections with the Jagiellonian dynasty patrons (including King of Hungary) and rulers of Prussia makes this attribution highly probable. The author of the painting portraited himself in the painting observing the battle and gazing upwards through intertwined fingers.
