Ibn Kabar

Ibn Kabar (Shams al-Riʾāsa Abū al-Barakāt ibn Kabar, d. 1324) was a Coptic Christian author of an ecclesiastical encyclopedia known as Mișbâḥ al-ẓulma.

He was secretary to the Mamluk minister Baybars al-Manșûrî, presumably editing the latter's work Zubdat al-fikra fi ta'rîkh al-hijra ("quintessence of thought in Muslim history").

He had to flee the persecution of Christians in 1321, and died shortly after.
