This special Christmas edition of 60 Minutes features two segments from previous programs. From April 10, 2011, Morley Safer tours the Vatican Library, which holds some of the oldest and most precious works of art and treasure known to man. From April 24, 2011, Bob Simon presents a two-part feature in which he steps back in time getting rare access to monks in ancient monasteries on a remote Greek peninsula, whose lives and routines have remained constant for a thousand years. Bob sees many aspects of the monastic life including chanting, prayers, rituals and priceless relics and icons from the Byzantine Empire.
