That's "Reply of the Zaporozhian Cossacks" by Repin, hanging in the State Russian Museum, St. Petersburg.
As the story goes, in 1676 the Turkish Sultan, despite being beaten by the Cossacks when he tried to invade what is now southern Ukraine, demanded these guys surrender and submit to Turkish rule.
As can be seen, the Cossacks thought this was the funniest thing they had ever heard and wrote a letter in response.
A very profane, very defiant, very vulgar, very contemptuous letter.
These old boys just cracked themselves up with their letter.
And that's what I think of when I think of Russians and Turks.
After Turkey’s downing of a Russian jet along the Syrian border on Nov. 24, 2015, Russian President Vladimir Putin warned of “serious consequences for Russia's relationship with Turkey.” He described the incident as a “stab in the back,” sending a message to Turkish President Recep Tayyip Erdogan that he saw the downing of the plane as a betrayal. Russia soon slapped economic sanctions on Turkey, and the $38 billion trade volume between the two countries began to shrink. Turkey was seriously hurt, as many sectors of its economy ran into a wall.Also at al-Monitor:
