Friday’s vandalism of the famous painting of Ilya Repin, “Ivan the Terrible and His Son Ivan, 16 November 1581” was a shocking incident, but not an isolated case. That particular painting had been both banished and slashed in the past. And other works of Russian art have been destroyed or damaged for political and religious reasons. Most of the cases were heinous. A few were perhaps less vengeful – but not less expensive to repair.
