St. Nicholas the Wonderworker was the Archbishop of the city of Myra in the Roman province of Lycia in the 3rd century A.D. Then the Roman Emperor Diocletian violently persecuted Christians, but in the year 324, Constantine the Great became the Roman Emperor. He made Christianity the main religion in the Empire and ordered to release all captive Christians from prison.
St. Nicholas distinguished himself with his wonders: he healed the sick ones; appeared in the dream of the Emperor and convinced him not to execute the erroneously convicted; on one occasion he raised from the dead a drowned sailor, after which St. Nicholas was considered to be a patron of seamen.
The cult of this Saint emerged way back in the 4th century, soon after his death, and spread over Russia in the Middle Ages. The earliest icon of St. Nicholas in the territory of Russia appeared in Kiev in the 11th century, and is now kept in the St. Sophia Cathedral.
