"an icon of the Venerable Sergius"

 The Venerable Sergius of Radonezh was a medieval Russian monk, a spiritual leader who became one of Russia's most venerated saints. He was an ascetic who taught his followers to live simple lives, supported by their own labour. He died on 25th September (now his feast day) in 1392 and was canonised in 1452. The Roman Catholic Church also recognises him as a saint.
