Editing Lost literary work (section)

===13th century===

* The Quaternuli by [[David of Dinant]]. Which were condemned by a provincial council headed by [[Peter of Corbeil]] in 1210, who ordered for them to be burned for expressing pantheist beliefs. David may have also published another work, entitled De Tomis, seu Divisionibus. Though it is likely this may be another title for the Quaternuli.

* The literary tradition of the [[Nizari Ismailism|Nizari Ismailis]] ("Assassins"), partially destroyed during the reign of [[Hassan III of Alamut]], and eventually lost completely during the [[Mongol campaign against the Nizaris]], in particular during the burning of the Library of [[Alamut Castle]]
** ''Sargudhasht-i Bābā Sayyidinā'' ({{langx|fa|سرگذشت بابا سیدنا}}), Hasan Sabbah's biography. Juvayni "saved" it before burning the library, and used it as a source in his ''[[Tarikh-i Jahangushay]]'', but he claimed that he burned it after reading it.<ref name=Willey2005>{{cite book |last1=Willey |first1=Peter |title=Eagle's Nest: Ismaili Castles in Iran and Syria |date=2005 |publisher=Bloomsbury Academic |isbn=978-1-85043-464-1 |pages=75–85 |url=https://books.google.com/books?id=RTyTn4ErwRIC |language=en}}</ref>
