Pope from July to Dec. 1294. He became a Benedictine at the age of 17, but retired to Monte Morrone, where the many disciples who gathered round him became the nucleus of the Celestine Order. Elected Pope when he was nearly 80, he was naïve and ignorant of procedure and became a tool of Charles II of Naples; he abdicated. He is often known as St Peter Celestine from his baptismal name of Peter. Feast day, 19 May, no longer in the calendar of the universal Church.
