The Vatican is hosting an unprecedented exhibition of Russian fine art, bringing treasures from Moscow’s famed Tretyakov Gallery to Rome following a sold-out exhibit of Vatican works at the state museum two years ago.

The Tretyakov is loaning some of its most important paintings and religious icons for “Pilgrimage of Russian Art: From Dionysius to Malevich.” Many of them are leaving the gallery for the first time.

According to the curator, the exhibition looks into the diversity of Russian perception of art and points out the succession of spiritual traditions, an inner and deep connection between icon-painting and Russian realism of the 19th century.
