Celestine (Popes), the name of five popes, the most notable of whom was Celestine V. (Pietro Morone), who, after being a hermit for sixty years, and founding the Order of Celestines, was, against his wish, elected Pope, an office for which he felt himself entirely unfitted. In a few months he abdicated, and his successor, Boniface VIII., put him in prison till his death, which happened in the next year.
