Mystic Lamb altarpiece unveiled in Belgium after four-year restoration

A Catholic altarpiece which has been called "the most influential painting ever" has been restored after four years of work.

Today, the altarpiece, also known as The Adoration of the Mystic Lamb, was unveiled in St Bavo’s Cathedral, Ghent.

The altarpiece is thought to have been begun by Hubert van Eyck, who died in 1426, and subsequently completed by his brother Jan.

Its features 100 figures with various Biblical scenes, including the Annunciation. Its central panel shows a sacrificial lamb, representing Christ, on an altar bleeding into a grail.
