Sawirus (Severus) ibn-al Muqaffa

Severus ibn al-Muqaffa was a Monk who became a Coptic Bishop. He is regarded as the redactor of an earlier series of biographies written in Coptic which he translated into Arabic in the 10th century CE (Coptic Encyclopedia). This collection of biographies is known as the History of the Patriarchs of Alexandria (aka History of the Patriarchs of the Egyptian Church). A mid 8th century CE earthquake is mentioned in the biography of Michael I (aka Kha 'il I) who was the Coptic Pope and Patriarch of Alexandria from 744-767 CE. The biography is written in the first person and was ostensibly written by a companion of Michael I.
