"60 MINUTES" LISTINGS FOR SUNDAY, DECEMBER 25, 2011

THE LIBRARY - No one is allowed to borrow a book from the Vatican Library - except the Pope. And no wonder: the archive holds some of the oldest and most precious works of art and treasure known to man. Morley Safer and 60 MINUTES cameras get to see the best of the best. David Browning is the producer.

MOUNT ATHOS - 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. 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. Harry Radliffe and Michael Karzis are the producers. THIS IS A DOUBLE-LENGTH STORY.
