Abū Bishr Mattā ibn Yūnus al-Qunnāʾī (Arabic: ﺍﺑﻮ ﺑﺸﺮ ﻣﺘﺎ ﺑﻦ ﻳﻮﻧﺲ القنائي; c. 870-20 June 940) was an Arab Christian philosopher who played an important role in the transmission of the works of Aristotle to the Islamic world.
Abu Bishr was trained at the dayr Qunnā monastery (hence the name "al-Qunnāʾī"), a Nestorian institution not far from Baghdad, which supplied the government of the Abbasid Caliphate with many high-ranking officials.
Abu Bishr is best known for his Arabic translations of Aristotle and of his Greek commentators.
[2][3] Al-Sirafi also managed to confound Abu Bishr with a series of Arabic grammatical riddles.
[3] Abu Bishr's younger colleagues, Al-Farabi and Yahya ibn Adi would later offer additional arguments to support his case.
