Liber Pontificalis
Because of the use of the "vestiarium", the records of the papal treasury, some have hypothesized that the author of the early "Liber Pontificalis" was a clerk of the papal treasury. Edward Gibbon's "Decline and Fall of the Roman Empire" (1788) summarised the scholarly consensus as being that the "Liber Pontificalis" was composed by "apostolic librarians and notaries of the viiith and ixth centuries" with only the most recent portion being composed by Anastasius.
