A chest CT scan taken Tuesday evening showed the “normal evolution” of an infection as it is being treated, the Vatican said in its late update.

Pope Francis, who is being treated in hospital for double pneumonia, slept well overnight and is resting, the Vatican said in a brief statement on Thursday. The 88-year-old pontiff was spending his 14th day in Rome's Gemelli hospital after coming down with a severe respiratory infection that triggered various complications.

Time-honored rituals, drafted and refined over centuries, allow time for mourning and provide order at a dramatic moment of transition.
