'Stańczyk' by Jan Matejko, 1862.

He was a real court jester who served in the court of three Polish kings over the years. The painting shows him sad while we can see a party is going on in the background with people laughing. The document on the table next to him is one announcing that Russian troops have recently conquered Smolensk which is what Stańczyk is reacting too. The party in the background is being held to celebrate a minor Polish victory in their war against Russia, but Stańczyk realizes that the Russian victory at Smolensk is much more crucial and at this point, Russia has basically won the war over Poland.
