The Holy Mountain (Mount Athos • GREECE)

Bob Simon steps back in time when he gets rare access to monks in ancient monasteries on a remote Greek peninsula who have lived a Spartan life of prayer in a tradition virtually unchanged for a thousand years.  
"60 Minutes" cameras capture the monastic life, including chanting, prayers, rituals, and the priceless relics and icons from the Byzantine Empire stored on "The Holy Mountain," Mt. Athos. Bob Simon reports.
