At-Tabarī
Muhammad ibn Jarir al-Tabari and the Khuzistan Chronicle both report that the search for fragments of the true cross involved torturing clergymen. The Opusculum de Persica captivitate is a document attributed to Modestos. It gives a death toll of 65,000. This number may give an idea of the total Christian population in and around Jerusalem. The Chronicon Paschale is notable because it does not accuse the Jews of Anti-Christian violence or sedition during the fall of Jerusalem in 614. It is loosely dated to June 614. Another important document is Modestos' Letter.
