Beneath a glass coffin, wearing a pontiff's miter and faded vestments of gold and purple, there lies a tiny man with a wax head.
This represents an Italian priest who, until this month, was the only pope in history to voluntarily resign.
His name is Celestine V.
Celestine became pope at 84, some seven centuries ago, after a long and self-punishing career as a hermit.
Though a celebrated spiritual leader, and founder of a new branch of the Benedictine order, his papacy lasted just over five months. It's widely viewed as an utter disaster.
