In Greek mythology, Heracles, or Hercules, the son of Zeus, performed 12 labours: a dozen incredibly difficult and highly dangerous tasks.
But slaying the Neamean lion or battling the Lernaean hydra must have been a walk in the park, compared to what Vladimir Putin has had to deal with. At least, that's the impression you get from this bizarre exhibition.
The original 12 Labours of Hercules were acts of penance and toil performed by the Greek hero. To mark Vladimir Putin's 62nd birthday, Hercules' tasks have been given a Russian makeover. Mythical monsters have been replaced by modern monstrosities such as terrorism.
Mr Putin grapples with the multi-headed hydra... of Western sanctions. The EU, US, Canada and Japan imposed sanctions after accusing Russia of supplying separatist rebels in eastern Ukraine with heavy weapons and soldiers - an accusation Russia denies.
Mr Putin is depicted stopping Western intervention in Syria - a reference to Russia's veto at a UN Security Council vote in 2012. The exhibition has been organised by the Vladimir Putin Supporters Group on Facebook. The artists however, are a mystery.
