From shirtless demigod to Greek superhero. A Moscow art exhibition honored Vladimir Putin yesterday on the eve of his 62nd birthday by portraying him as Hercules. The one-day exhibit — organized by a student who heads an online Putin fan club — included paintings of the Russian president completing his own version of the hero’s famous 12 labors. Instead of slaying the nine-headed Lernaean Hydra, for example, Putin raises his shield against Western sanctions. Classicists may find the art comes on a bit strong.
