Last month, when Vladimir Putin ordered that the Black Madonna of Kazan, the holiest icon of the Russian Orthodox Church, be flown over the Black Sea, many believed he wished to secure blessings for the Winter Olympics in Sochi.
It was the first time the icon, or rather a copy of it, since the original was stolen and possibly destroyed in 1904, was deployed to bless a peaceful enterprise. Over the centuries, the “Black Virgin” has been taken to battlefields to bless Russian armies fighting Swedish, Polish, Turkish, Persian, French and German invaders. Stalin sent it to Stalingrad in 1943 to ensure victory over the German invaders under Field Marshal Friedrich Paulus.
