Episode notes
Liber Pontificalis As Constructed History
- The Liber Pontificalis is a serial papal biography compiled from 6th-century papal archives and earlier lists like the Calendar of 354.
- Its authors shaped a continuous narrative that presented Roman bishops as the sole authoritative lineage from St. Peter onward.
Standardized Papal Biographies
- The Liber Pontificalis uses a strict formula: origin, length of pontificate, deeds, ordinations, burial, and vacancy.
- This formula preserves administrative details while leaving room for variable narrative length.
Gaps And Selectivity In The Record
- The Liber Pontificalis often omits context and specifics, especially about martyrdoms and internal disputes.
- Historians must fill gaps with archaeology and other early sources to reconstruct likely realities.
