LONDON (Reuters) - Pope Benedict XVI gazed out on the crowd packing the piazza of a small Italian town. Below him lay the bones of Celestine V, the last pontiff to choose to retire; above rose sunlit crags where the "hermit pope" took refuge from a troubled mediaeval world.
A few weeks after that visit in July 2010 to Sulmona, in the Abruzzo mountains, the then 83-year-old Benedict told a fellow German he would not hesitate to become the first pope since Celestine in 1294 to resign of his own free will, if he was no longer able - "physically, psychologically and spiritually" - to meet the demands of running the billion-strong Catholic Church.
