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 was ordained as a priest in 1300, under the name of Barsum and took office in Mu'allaqah, the ancient Coptic church in Cairo. A number of rhyming Arabic sermons of his have been preserved. He had to flee the persecution of Christians in 1321, and died shortly after.
