Hans Krell started his career as court painter of George the Pious, Margrave of Brandenburg-Ansbach in Ansbach.

[2] He then entered into the service of King Louis II of Hungary in Prague and Buda, where he was employed as court portraitist in the years 1522–1526.

[4] 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 the Kingdom of Poland on one side and the army of the Grand Duchy of Moscow on the other.

According to specialists, the author must have taken part in the battle himself due to his high knowledge on the subject.

[4] Krell's connections with the Jagiellonian dynasty patrons (including king of Hungary) and rulers of Prussia makes this attribution probable.
