AL-THIQA IBN AL-DUHAYRI (?-after 1267)
A Scholar of Coptic.
Whether or not al-Thiqa ibn al-Duhayri is the Ibn al-Duhayri who was consecrated Metropolitan of Damietta with the name Christodoulos by Patriarch Cyril III ibn Laqlaq, he is remembered as a scholar who wrote a highly regarded Bohairic grammar, Muqaddimat al-Duhayri. Al-Thiqa sought to improve on the earlier grammars of Yuhanna, Bishop of Samannud, Ibn Katib Qaysar, and al-Wajih Yuhanna al-Qalyubi, refining Ibn Katib Qaysar’s threefold division of material into nouns, verbs, and particles, and adding many examples. Al-Thiqa corresponded with scholars such as al-Mu’taman ibn al-‘Assal, whose Bohairic-Arabic lexicon he praised; his own grammar was judged to be “good” by Abu al-Barakat ibn Kabar, and by many others, to judge from the large number of manuscripts in which it is preserved.
