The "sede stercoraria", the throne with a hole in the seat, now at St. John Lateran (the formal residence of the popes and center of Catholicism), is to be considered. This and other toilet-like chairs were used in the consecration of Pope Pascal II in 1099. In fact, one is still in the Vatican Museums, another at the Musée du Louvre. The reason for the configuration of the chair is disputed. It has been speculated that they originally were Roman bidets or imperial birthing stools, which because of their age and imperial links were used in ceremonies by Popes intent on highlighting their own imperial claims (as they did also with their Latin title, "Pontifex Maximus").
