A Russian businessman has donated more than 70 icons with an estimated value of Ru 30m (around $1m) to the Russian Orthodox Church. Property mogul Sergei Shmakov has spent over a year tracking down the icons—which were taken out of Russia after the Bolshevik Revolution and during the second world war—at auctions, antique stores and flea markets abroad. The icons include a rare mid-18th-century icon, St John the Theologian in Silence, which depicts the apostle with his fingers over his lips and an angel peering over his shoulder as he contemplates the gospel he is composing.
