The History of the Patriarchs of Alexandria is a major historical work of the Coptic Church. It is written in Arabic, but draws extensively on Greek and Coptic sources. It is a compilation said to have been begun by Severus ibn al-Mukaffa and based on earlier biographical sources. It was continued by others including Michael, bishop of Tinnis (11th century, writing in Coptic, covering 880 to 1046), Mawhub ibn Mansur ibn Mufarrig, deacon of Alexandria., and Pope Mark III of Alexandria (for 1131 to 1167)
