Ibn Zafir
Ibn Zafir was an Egyptian chancery secretary and man of letterswho was born in Cairo in 1171 CE and died there in 1216 or 1226 CE (Encyclopedia of Islam v. 3, 1991:970-971). Roughly a dozen works are attributed to him of which several have survived. His most notable work may be Kitab al-Duwal al-munkati'a
of which Akhbar muluk al-dawla al-saldjukiyya may form a part(Encyclopedia of Islam v. 3, 1991:970-971). Inside is apparently some Fatimid history.
