Oct. 3 (Sept. 20 old calendar).

Faithful prince Oleg Romanovich, baptized Leontius, was the prince of the Briansk area and the grandson of prince Michael of Chernigov, killed by Tatars in the Horde (see above). Saint Oleg was disinterested in wealth and worldly glory; he was drawn to monastic life. So he gave up the throne to his brother and took monastic vows and was given the church name of Basil. Saint Oleg became renown for the asceticism of his life. He ended his days peacefully at his monastery in 1289. His relics are preserved in the Peter and Paul monastery built by him in Briansk.
