Saint Leontius, Patriarch of Jerusalem, according to Saint Gregory Palamas (Nov. 14), he was Patriarch from 1223-1261. His life was similarly described by Theodore, a monk of Constantinople.
This Life was translated from Greek into the Russian language in an abridged form. It was translated a second time more fully by Saint Nicodemus of the Holy Mountain (July 14), who says the death of the Patriarch actually occured in 1175.
